Coltraco Introduces 3rd Generation Portagauge

Thickness monitoring is nearly impossible and one comes to know of it only when a hole is visible. Due to corrosion the inner side of metal containers decomposes but looking from the outside it goes unnoticed. Many accidents have happened in the past and they still keep on happening as the staff is unaware of the deteriorating condition of the container and all of a sudden the leaks emerge.

CEO Dr. Carl Stephen Patrick Hunter told the gathering The Portagauge 3 is our low cost Ultrasonic Thickness Gauge. It was developed to remain simple yet provide accurate results and meet modern thickness gauging requirements. He further added Utilizing the single echo technology allows the unit to maintain accuracy even on corroded or challenging surfaces. It is a highly dependable unit for testing corrosion.

The package includes

    • 1 Portagauge III Unit
    • 1 10mm Sensor
    • 1 Peli 1120 Case
    • Calibration Certificate
    • Operating Instructions

Coltraco Unveils Non Invasive Flow Rate Meter

Coltraco UK unveiled yet another amazing hand held device that can now allow industries to monitor their liquid flow in pipes right from the outside of the pipe. Monitoring liquid flow in pipe would not only allow measuring liquid usage but would also allow detecting blockage in pipes so that no unnecessary dismantling is required. Time is of the essence and when you know the exact location of a blockage within seconds, there are no delays in making the right decision.

CEO Dr C.S.P Hunter during the uncovering said “Portasonic consists of a handheld portable clamp-on transit time flow meter device for accurate flow measurement from outside a pipe – especially for fire protection water sprinkler and fire hydrant systems. The unique clamp-on fixture design makes the installation very straightforward and requires no special tools or skills and due to the non-invasive nature of clamp-on transducers, there is no pressure drop, no moving parts, no leaks, and no risk of contamination or corrosion. Ideal for the measurement of flows in clean, non-aerated fluids such as water, water/glycol and oils in full pipes from 1/2 to 180 (12 to 4570 mm) diameter can be measured and the ultrasonic signal penetrates all common metal and plastic pipe materials.

Coltraco is a leading ultrasonic hand held devices manufacturer that enables industries to work with ease and perfection. Being a hand held device the Portasonic stands as tall as:

Height: 204 mm (5.75 inches)
Width: 100 mm (3.50 inches)
Depth: 35 mm (1.00 inches)
Weight: 600 grams (11.5 ounces)

Marine Fire Protection: An Ungoverned Space

Fire protection remains an “ungoverned space” within the maritime industry.There are are too few qualified engineers who may be considered subject matter experts in marinefireengineering, and too often, marinefireprotection is seen as a cost than an investment and something vital to the overall business activity of the customer. A “safety first” culture often remains both un-pursued and unrewarded.

In terms of ships extinguishing systems there exist two broad categories: sprinkler systems and gas systems. The former can suffer leakage, but the latter can cause catastrophic effect given its physical pressures. Overall, the value of the marine assets thatfiresystems protect is increasing rapidly but the competitive nature of the free market in thefireand marine industry places great pressure on it to deliver systems which often only minimally comply with the regulations and deliver the asset protection at the most economical cost.

Our experiences in the shipping industry globally have included wonderful ones of professionalism and care from dedicated former chief engineers, master mariners and fleet managers. Over 25 years we have received technical advice from some of the leaders in the industry both in the UK and the USA but also from Canada, Australia, Germany, Hong Kong, Denmark, Norway and Singapore. Trade and certification organizations such as the Institute of Marine Engineers, Science & Technology,Fire Industry Association, International Marine Purchasing Association, Shipbuilders & Suppliers Association in the UK and the NFPA and UL in the USA have become a part of our fabric.

Set alongside these positive developments, however, are anecdotalexperiences which are highly concerning:

- Systemsportrayed and installed by contractors as NOVEC1230 fire protection fluid but filled with sand or water.

- High pressure gas systems without the means to actuate them.

- Bathroom weighing scales being chained to the CO2 cylinders in an effort to comply with IMO SOLAS FSS Code regulations.

- Cheap cylinder pressure gauges sticking in position under humidity or mechanical fatigue.

- Safety pins being retained in position in the cylinder valves after installation.

- Marine CO2 systems with an estimated 20% of the CO2 cylinders installed on commercial shipping being empty or partially-filled.

- Over-filled and under-filled cylinders.

- Pipework and cylinders freshlypainted but with severe internal corrosion leading to particulates of rust which block the discharge nozzle mechanism.

- Room integrity testing with questionableresults and with the room integrity remaining un-monitored after testing.

- Liquefied gas extinguishants being confused by installers and customers with Inert gas systems.

- A lack of understanding of the organic compounds of some liquid extinguishants and their corrosive effect on the cylinder in the event of condensate ingress.

- Shipping companies not implementing the FSS code of the IMO SOLAS regulations.

Our Safesite™ and Safeship™ concepts aim to deliver technologies which enhance safety at customer critical infrastructure at sea and on land, putting safety first.


In aerospace, if a fault occurs on an aircraft that information is quickly and openly shared with airline operators, civil aviation authorities and engineering organizations. In contrast, in shipping, unless a fatality occurs it is left un-reported. The number of ships with partially-filled, over-filled or empty cylinders and the number of accidental discharges or slow seepages are occurring are left un-shared and unknown. Serious accidents involving fire protection equipment do occur:

September 2004 – Hong Kong - A routine inspection of the fixedCO2fireextinguishing systemled to the death of four officers (HKSAR, n.d.)

November 2008 - Akula II K-152 Nerpa - At least 20 people died on a Russian nuclear submarine when a Halonfireextinguishing systemwas activated by mistake (BBC News, 2008 and Red Banner Northern Fleet, 2008).

May 2010 – The uncontrolled release offire-extinguishing gas into engine room of the Marsol Pride, at Tui oil and gas field (TAIC, 2011)

August 2011 - Accidental discharge of carbon dioxide on board SD Nimble, resulting in serious injury to a shore-based service engineer at Naval Base Faslane (MAIB, 2011)

July 2014 - Port Hedland, Western Australia –Afirestarted in the engine room of the bulk carrier Marigold. Firefighting by the ship’s crew included activating the Halon gasfixedfiresuppression system for the engine room. However, a full release of Halon gas did not occur, nor was the engine room effectively sealed. (Safety4Sea, 2016)

February 2015 – Twenty-nine Palms, California - 22 U.S.Marines injured when a Halon-filledfireextinguisher went off (Bustle, 2015)

Marine Servicing

Marine servicing companies bid to service a ships CO2 system; this can comprise two hundred to six hundred 45 kilogram CO2 cylinders per ship. These are under 720 psi/ 49 bar of pressure. They can discharge accidentally or be subject to slow seepage. Some marine service companies estimate that at one time 20% of a ships CO2 cylinders have discharged or partially leaked their contents and there are over 55,000 commercial vessels at sea at any time.

Servicing is often done at sea, and the ship may only be available to the contractor for four hours; the winning contractor is often the one who bids lowest. Historically, and as only one component of a CO2 system inspection, these marine service crews shut down the CO2 system, dismantle it and weigh each cylinder.

On average each cylinder will take 40 minutes todismantle, weigh, record and re-install, meaning that it would take 400 man-hours to achieve that on a 600 cylinder marine installation.

Using a type-approved ultrasonic liquid level indicator, a perfect condition cylinder can be checked for contents in 30 seconds; the average time to record and validate readings should take 1-3 minutes per properly-filled cylinder.This still equates to 10 to 30 perfect man-hours for this task alone.Too many times, therefore, good marine servicing companies may not have the minimum amount of time required to perform the inspection.

However, there are other companies who are said to randomly check some cylinders and then place “tested stickers” on the rest.Testing is important: because the normal design concentration of CO2 of 34-72 v/v % is above the nearly immediate acute lethality level, an extremely narrow safety margin exists for these systems.

Given the risk and the difficulties of manual inspection, it seemsunfathomable then that thesesystems are not permanently monitored rather than leaving them to stand alone unsupervised 364 days a yearuntil their annual certification.

UK Technology

High value shipping assets are critical infrastructure to the global economy with widespread effects in the event of their downtime or shutdown. Their asset values requiringfireprotection far exceed the delivery of minimal compliance and the cost or damage to reputation far in excess of the cost of a real-time monitoring system.

Technologies exist right now that can mathematically and far more efficiently test room integrity. They exist to quickly, momentarily and highly accurately identify pipework corrosion. Gases under pressure can be monitored and liquefied gases can be permanently monitored. Contents and pressure can be simultaneously monitored offering remote diagnostics and remote monitoring capabilities and can extend to the delivery of autonomous systems in relation to them.

Technologies are soon to exist to monitor both liquid content and gas pressure of a cylinder safely –from theexternal sidesof the cylinderrather than within it– in bothfixedand portable forms. If we can monitor the contents we can calculate the mass/weight of the liquefied extinguishant.

These technologies offer great opportunity to theindustry. They enable customers to have confidence that afirecompany has installed a gaseous extinguishing system with a semi-autonomous monitoring capability to safeguard it. What CEO of a shipping company today wants to be shown to have installed afiresystem that is left standing and unsupervised over thousands of miles of open seas and often in extreme weather states until its annual certification check?

This is presently an “ungoverned space” in the maritime sector. As the world changes, so must our industry integrate technological solutions to provide a bulwark against minimal - and even occasionally flagrant - disregard to the application of standards and good engineering practices.

Fire outbreak in Data Center causes delays at Ford Corporate Headquarters

Ford is working to recover after a fire broke out at a power sub-station beneath its US corporate headquarters, briefly shutting down data center operations and prevented it from gathering sales data. The automotive giant is reported to have the building completely evacuated in Dearborn MI. As a result the power had to be completely cut off and the servers which had to receive sales data from dealerships all over USA were temporarily cut off from the internet. During the incident no injuries were reported and the fire was brought under control after a few minutes but until it became apparent that every nook and cranny was cleared for every kind of risk the building was opened for the staff to enter again.

Coltraco Provides Devices Used For Monitoring Fire Suppression Systems

Coltraco is an ultrasonic level indicator manufacturer, a family company, with 3 generations of the family working for the business alongside an extremely talented group of individuals, all who share our values and commitment to science and commercial integrity. The company was founded in 1987 by Mr. E C Hunter, a Royal Naval (RN) Submariner 27 year at sea & his son Mr. Carl Stephen Patrick Hunter, the current CEO.

Mr. E C Hunter spent 5 years working for the Admiralty Research Laboratories, specialising in sonar technologies. It became clear to him that marine CO2 suppression systems could benefit from a portable ultrasonic device, able to monitor the contents. Methods at the time involved either weighing cylinders, or using testing devices that included a radioactive source. Identifying a significant market opportunity, with large commercial vessels typically holding up to 600 x 45KG cylinders on-board, Mr. E C Hunter retired and set to work. By 1987 he had produced the world’s first dedicated marine portable liquid level indicator, able to monitor multi-banked rows of cylinders aboard commercial vessels. Whilst the original monitoring device was complex to use, its accuracy was unparalleled, able to read cylinders to within 1/8th of an inch or +/- 1.5 mm. It took another 3-4 years until 1990 to develop a unit which was more user-friendly. Today, Coltraco have equipped over 9000 ships, 25 Navies, 1000 offshore oil & gas platforms, 100 power stations and 5000 fire safety companies. We export our state of the art modern liquid level indicator and other devices under our banner to 105 countries and exports constitute 85% of our output.

Accident Reports: Seafarers Ignore Safety Management Systems by Maritime Executive

The procedures and safe working systems that lie at the core of all safety management systems are there for a reason, says Steve Clinch, Chief Inspector of Marine Accidents at Marine Accident Investigation Branch (MAIB).[…] MAIB investigators regularly identify a disconnect between the safety culture that shore-based managers believe (or perhaps hope) is in place within their fleet and what is really happening on board. Safety management systems need to evolve over time if they are to remain credible. If the procedures on board your vessel are not working, don't just use convenient work around to get tasks done – flag up the problem and make sure they are changed or amended in a controlled way that ensures the system retains its credibility and continues to reflect the company's best practice requirements. In the digest, Captain John Rose, Director of the Confidential Hazardous Incident Reporting Program (CHIRP) highlights the importance of crew’s ability to deal effectively and safely with the complexity, difficulty, pressures and workload of their daily tasks, not only in emergency situations, but also during routine operations. The report is available here.

Coltraco Is Now Recognized As an Industry Leader

Coltraco is a family owned business with most of our family members working for its success today. But we havent become selfish by not allowing others to become a part of it and we have now many talented young people working for us taking the business to the next level. Our liquid level indicator is by far the most accurate device to measure liquids inside all kinds of containers. Our devices can measure liquids under extreme conditions without fail and this is what makes our devices great. It truly reflects our zeal and

enthusiasm to refine what weve already created and to take our devices to the next level.

We endeavor to give the sea business the best gadgets that can be utilized for identifying spills so they can locate a reasonable arrangement well inside time. Aside from simply concentrating on cable transit areas watertight testing the Portascanner is totally fit for helping with watertight hatch covers testing. Therefore this gadget can be utilized to filter the whole ship and guarantee that when the ship sets out for a voyage there is no possibility of water leaking inside the lodges or freight holds. A dry ship is a protected ship as water not just purposes harm to products or cause freeze inside the lodges, it builds weight which can regularly end up being deadly for the prosperity of the ship and the group that sails with it.

About Coltraco

Coltraco is well known for its Portalevel the ultrasonic level indicator that completely revolutionized the ways of measuring liquids on the industrial scale. In the past measuring liquids was a great hassle and most industries suffered many losses when they couldn’t control the use of liquids in manufacturing and other processes. As the world advanced so its need for a sophisticated liquid measuring device became undeniable.

Coltraco successfully replaced the old liquid level indicator with its powerful devices and with the passage of time they were upgraded to meet the modern industry challenges all over the globe.

3 Ways to Improve Fire Safety in Power Generating Stations

It is common knowledge that power generating facilities are safety critical and extremely high value assets. As a result, there is a great focus on business continuity due to the pressures and costs incurred due to accidents, faults, fires, or other temporary outage disruption. Here are 3 ways we have helped these businesses and will do in the future:

CONTINUOUS MONITORING: Our first ever made-to-order fixed, permanent, continuous monitoring system was for Sellafield Nuclear Power Generation Plant in the UK over 12 years ago.

MORE FREQUENT INSPECTIONS OF FIRE SYSTEMS: Currently there is a major power generation player in the USA keen to Portalevel® MAX an unbeatable ultrasonic level indicator following a recommendation by leading insurers, FM Global. We are in discussions with several leading power generation companies in North America who will be serviced and supported by our American Strategic Partners.

INTEGRATED REAL-TIME MONITORING OF FIRE SYSTEMS: Now we offer this Safesite® smart solution liquid level indicator so the facilities safety manager will be instantly alerted in the case of agent leak, to ensure the system’s integrity.

Here are some extracts from an interesting article on electric generation stations from PowerMag to illustrate. “Occurrences at Thermalito Power Plant (California) in 2012, Detroit Dam (Oregon) in 2007, and Watts Bar Hydroelectric Plant (Tennessee) in 2002 resulted in major electrical fires. In almost all cases, the fires caused forced shutdowns, some for a year or more. The loss of generation as the result of an electrical fire often outweighs the actual fire damage.” [sic]“Even after a relatively small fire, smoke and soot removal can cost several millions of dollars in facilities with large open spaces. For example, cleanup costs at Thermalito were reported at approximately $90 million, with a total cost of the fire around $200 million. SOURCE. Here are further extracts taken from PowerMag: Hydro plants are not without fire risk, and history reminds us that large-loss fires have occurred (see table). SOURCE

Invited to the All-Party Parliamentary Group for Maritime and Ports

With great honour and at the invitation of the All-Party Parliamentary Group for Maritime and Ports, and with thanks to Clare, our amazing Head of Communications & Government Relations, we attended the annual session of the AAPGMP in Select Committee Room 16 at the House of Commons last week.

Chaired by the Rt Hon Jim Fitzpatrick MP the meeting was addressed by the Rt Hon John Hayes MP, Minister for Shipping who, speaking to the worshipful Company of Shipwrights earlier this month in London said something we wholly support, “On your shoulders rests Britain's future as the world’s leading maritime nation. If, 100 years from now, we are still to be famous as the country that builds, repairs and maintains the finest vessels that sail the seas; if we are still to be renowned as the home of shipbuilding genius and skill; and if we are still to be celebrated as the nation that leads the world’s maritime affairs, it will be because those in this room today seized the opportunity to learn, to train, and to excel at everything you do.

We are a leading UK company with state of the art ultrasonic devices that help the maritime industry work without delays. Our world famous Portascanner is the perfect device for immediate and flawless hatch cover maintenance and watertight integrity testing. As ships face a lot of wear and tear during their voyages, many cracks and leaks appear without the crew knowing about them. Most of them appear in hidden places where the human eye cannot see. This proves to be lethal when the next voyage takes place as the goods get water damaged and the sipping company faces a lot of criticism and not to mention losses.

We strive to provide the maritime industry with the best devices that can be used for detecting leaks so they can find a suitable solution well within time. Apart from just focusing on hatch covers integrity testing, the Portascanner is completely capable of assisting in watertight compartment doors testing. Thus this device can be used to scan the en tire ship and ensure that when the ship sets out for a voyage there is no chance of water seeping inside the cabins or cargo holds. A dry ship is a safe ship as water not only causes damage to goods or cause panic inside the cabins, it increases weight which can often prove to be lethal for the well being of the ship and the crew that sails with it.

Coltraco Announces New Agent Fill Weight of a Fire Suppression Cylinder is delighted to announce the Portasteele Calculator, a highly effective agent fill weight of a fire suppression cylinder. The ultra modern device achieves its goal when the operator filling in the liquid level height using the Portalevel unit along with the cylinder proportions and its surrounding temperature reading produces Lbs or KG reading for all fire suppressant gases.

“We are incredibly pleased to be able to provide this unique agent fill weight of a fire suppression cylinder,” says CEO Dr Carl Stephen Patrick Hunter. “Until now the ability to measure agent fill weight wasn’t error free and an error can cause a huge setback to the safety measures taken” Dr Hunter continues to explain.

Coltraco is a leading manufacturer with over 18 products and systems. It strives to design, implement and manufacture the most advanced technology in the field of ultrasonic liquid level indicators. Being a family company, with 3 generations of the family working in the business, many highly talented individuals have also become a part of it who share the same values and commercial integrity.

The Rise of Coltraco

For many years Coltraco only manufactured 2 – 3 ultrasonic products. Out of these limited products, Portalevel and Portascanner gradually became world leaders. The Portalevel became famous for its remarkable results as an ultrasonic level indicator (of fire suppression systems). On the other hand, the Portascanner gained worldwide fame for being a flawless device when used for hatch cover maintenance and watertight integrity testing. Equipped with the latest ultrasonic technology, it became the very object to replace the traditional leak detection methods for ships hatch covers, Naval cable transit areas, offshore oil & gas watertight doors and scuttles respectively.

Its primary objective is to engineer, build and provide support to the US Navy Fleet in combat systems. It is one of the prized possessions of the US Navy and has proven to be a great resource in defending the country’s water territory and beyond.

Coltraco A Trusted Liquid Level Indicator Supplier

When there are tons of firearms onboard, you certainly need to keep a check on the fire safety systems. The 110 Portalevel units serving the US Navy have proven their worth in all conditions. However the units must be calibrated regularly to ensure their performance is up to date. When a ship is out in the oceans, there aren’t many options for survival if a fire breaks out. Damage can be reduced or controlled by the timely action of the fire suppression system. Be it a training drill or checking the pressure for a refill, the units provided to the Navy through Ascoa Fire Systems have successfully met their 1/8” accuracy requirement on High Pressure Halon systems.

Using the ultrasonic technology, Coltraco has come forth with the best range of liquid level indicator which not only serves military purposes but is also of great use in industrial sector. Over the years the product has undergone many enhancements to stay in lead in the niche and so far there isn’t any match of the Portalevel. We are proud of the fact that our products have proven their worth wherever they are being used no matter how long the buyer decides to keep them using.

  • 1 Destroyer
  • 12 Frigates
  • 4 Patrol Submarines
  • 12 Coastal Defense Vessels
  • 8 Unarmed Patrol/Training Vessels
  • Several Auxiliary Vessels

To keep its fleet in perfect order and respond to any kind of emergency call, it was essential to maintain the vessels and other machinery under its flag. Using traditional maintenance methods was both time consuming and expensive. It is imperative to keep a constant lookout on the waters surrounding the country. With the addition of the latest ultrasonic level indicator by Coltraco, we are sure the Navy would be able to function more quickly and efficiently. It is a moment of pride for the company to announce their product was chosen among all the others. Choosing it above all others is a clear indication of its reliability and the ability to perform every task that was required by the Navy.

Portalevel is an ultrasonic technology powered handheld device which has the ability to measure huge amounts of liquid. Using its level sensing ability from the outside of the water tank, it is ideal for industries where sensitive liquids are handled or used.

Calibrating your equipment annually or every 5 years? Regulation or recommendation?

We are often asked about calibration, why it is important, how often it should be done and why. The reason we know calibration to be important, and recommend its annual service is because our equipment is designed to improve safety and best practice, so ensuring the equipment used to conduct such inspections is necessary. But don’t just listen to us: our manufacturer’s recommendation is based on clear cut regulations. Under ISO 17025 standards for the calibration of any monitoring or measuring equipment, it must be at least once a year.

At Rolls Royce the test cell for their Trent XWB engines are calibrated every 3 months. In the gas industry, customers are recommended to calibrate their detectors every 6 months, especially if they are using them in confined spaces, in order to sure they are maintaining their accuracy as per technical specifications. There are serious consequences if customers do not value the understanding of their tools or equipment, which unfortunately renders them at risk.

But, what about 5 year calibration certificates? On calibration and as a manufacturer of quality, we are clear that it is unsound, unsafe and unprofessional to compete on calibration as some of our competitors are offering 5 year calibration certificates. We do not wish to contravene ISO 17025. Nor do we wish customers to believe that it is the manufacturer that dictates calibration standards, which is not the case. However, we do not force the customer do anything because it is up to their discretion – the key here is that we will not issue calibration certificates beyond a year.

When you buy from Coltraco, you have confidence in the longevity of your equipment, aided by our Coltraco Customer Care Commitment, including life-time support. In addition, we have set up ODA Service Centres worldwide, with more coming online in 2017, so you can send your equipment for its calibration locally. We always do something “over and above” to enhance the unit for customers and we have a wonderful reputation as a consequence.

For more information: ISO 17025 is an international standard for test and calibration labs. The manual is available online
