THE ULTIMATE ULTRASONIC PORTABLE LIQUID LEVEL INDICATOR FOR LOW AND HIGH PRESSURE CO2 - HALON - FM-200® FIRE EXTINGUISHER SYSTEMS

OVERVIEW

Portalevel® from Coltraco is a dedicated liquid level indicator for fire extinguisher systems. It is the cost effective and environmentally friendly solution for checking the liquid contents of single and multi banked cylinder installations. It will also find the level of liquids in any single skinned metal vessel of less than 1" wall thickness.

Finding a liquid level with Portalevel® is simple. The sensor applicator is placed onto a cylinder above the expected level of the liquid and calibrated. Then a series of readings are taken on the cylinder to identify the level of the liquid. With experience, operators can detect interfaces between different types of liquids.

Portalevel® is a small compact instrument of rugged design with simple to operate push button controls. The liquid level is indicated by two separate displays, a red light LED display and a LCD digital readout.

The unit is supplied with a standard dry sensor incorporating a magnetic applicator to ensure correct positioning on all types of cylinders. A wet sensor for poor condition cylinders is also available.

An optional extension rod is available for monitoring the second and third rows of multibank cylinder installations.

Portalevel® is automatically calibrated to the cylinder under test at the touch of a button.

ANCILLARIES

Multi Bank Extension Kit

Designed for reaching cylinders in the rear rows of multiple cylinder banks. The unique rod design allows a sensor to be passed between tightly packed cylinders in multiple installations, so avoiding the need for moving any of the front row cylinders.

The extension kit contains an integral sensor and is essential for any user who needs to reach inaccessible cylinders or test large multiple cylinder systems.

Wet Sensor

A wet sensor is available for use on pitted or poor condition cylinders. The wet sensor, when used with gel, allows proper sensor contact with cylinders that have a poor condition or uneven surface.

The wet sensor is recommended for any user likely to encounter poor condition externally stored cylinders, in particular, C02 cylinders.

Carrying Case

The Portalevel® is supplied in a waterproof plastic carrying case ideal for transit and storage.

Slimline Infra-Red Thermometer

The physical properties of carbon dioxide are such that it changes from liquid to gas at 31° C Centigrade. Halon and other substitutes are similarly affected at the higher temperatures of 50° C and above. Therefore Portalevel® readings must be taken at a time of day when cylinder wall temperatures are below these levels. A slim line thermometer is available for checking critical cylinder temperatures in hot climates.

The Portatemp thermometer is recommended for any user operating in hot climates who is likely to encounter C02 cylinders stored outside or in temperature affected storage rooms.

MAINTENANCE AND SERVICING FOR THE COLTRACO Portalevel®

Warranty

The Portalevel® carries a three year warranty covering all parts and labour. Warranty is invalidated if any one other than Coltraco technicians opens or works on the equipment. (The sensor is convered by a one year warranty)

Maintenance and Servicing

The Portalevel® is designed to be maintenance free and, with no moving parts, if handled correctly, it will provide reliable service for many years. If damaged the equipment should be returned to Coltraco for repair or replacement.

Spare Parts

Users need not carry spare parts but may wish to keep spare sensors if they are operating many units.

Calibration

Calibration checks can be carried out by testing the equipment on a cylinder with a known level. We recommend that units are returned for annual recalibration, usually a requirement for any ISO 9001 operation using test instrumentation. Units returned for recalibration are generally tested and certified within a 48-hour turnaround period. Customers with a number of units may arrange for a loan unit if necessary.
