Overview

Safer and More Efficient Testing

Portamarine® is the ideal low-cost solution for testing marine fire suppression systems. Its tried-and-tested ultrasonic technology allows it to provide reliable test results to ±1.5mm for most CO2, Halon, and Clean Agent fire suppression systems. It is non-invasive and portable, meaning that a single operator with one Portamarine® unit can test an entire bank of cylinders of varying sizes and agents. The quick, easy, and accurate measurement process using Portamarine® allows for greater operational efficiency and a streamlined testing process with no downtime for the fire suppression system. Without the need to weigh and dismantle cylinders, contents can be checked safely and reliably by the crew themselves.

 

Removing Downtime and Risk of Accidental Discharge

Portamarine®’s non-invasive nature also removes any risk of accidental discharge, since it does not need cylinders to be disconnected and dismantled. When used alongside the Portasteele® CALCULATOR, the agent weight can be determined from the liquid level, meaning that an operator can calculate the amount of agent within a system without having to physically weigh cylinders. This allows for a faster, safer, and more efficient way to comply with marine safety standards like IMO SOLAS FSS Code and MSC.1/1318.

 

Tailored to Marine Environments

The Portamarine® is designed specifically for the marine industry:

  • Rugged and survivable construction with backlit LCD for operation in marine environments with poor visibility
  • Compatible with CO2 and Halons or Clean Agents for universal fire suppression monitoring at sea
  • Extension rod for measuring banked cylinders on board without disruption
  • Portable and handheld device powered by off-the-shelf AA batteries for easy transportation and extended use with no recharging
  • RINA Classification Society Accepted

Frequently asked questions

The Portamarine® can measure the level of a wide variety of liquids. The primary application is for checking the liquid level in fire suppression cylinders. These agents commonly include: CO2, FM200™ (standard size cylinders), NOVEC ™ 1230 (standard size cylinders), Halon agents, FE-13™, FE-25™, NAF S III™ and, most core Clean Agent systems.
The Portamarine® can identify the liquid level to ±1.5 mm of the actual liquid level. When using the Portasteele® Calculator to convert the liquid level to agent weight, the results are accurate to within 1%.
The Portamarine® is very versatile and works on a large range of cylinder sizes. We have an extensive range of products that can measure anything from 10 cm to over 15 m diameter, so get in touch to find out which unit is suitable for your application.
No, you can use any ultrasonic gel, available in most pharmacies, as well as petroleum jelly. Water will also work, but in hot environment needs very regular application.
No, unfortunately above this temperature CO2 converts into a supercritical fluid state meaning your cylinder will no longer have a liquid level to measure. We recommend testing CO2 in lower temperatures. Please, get in touch if you need recommendations for hot climate CO2 monitoring.
With the Portamarine®, you also get an extension rod that allows you to measure the liquid level in banked cylinders up to four deep.
Yes, however, these agents are far more stable at higher temperatures that CO2, and although the liquid level will naturally rise with increased temperature it is far less than with CO2 and, therefore, can still be tested.
Yes, this unit is specifically designed to work despite the presence of a siphon tube.
