Fire Safety Equipment Servicing

The complete ISO 14520 range for liquid and gaseous fire suppression systems content verification and enclosure integrity monitoring. Benefit from over 30 years’ experience in the fire safety industry. The leading range of instrumentation have been awarded the “Innovation of the Year for Fire”, as well as Safety Initiative Award Finalist.

Portagas® is a world’s first technology for non-invasive, non-destructive monitoring of pressurised, inert gas systems.

P/N: 3107505-GAS

The Portalevel® MAX PLUS is an all-new liquid level indicator with three extended calibration features and a display that will indicate if the sensor is in the GAS or LIQUID phase of a fire suppression cylinder. This portable and battery powered, liquid level indicator designed to non-invasively, accurately, and reliably measure the level of fire suppression agent contained within a cylinder. The UL-Approved Portalevel® MAX PLUS is suitable for CO2, most Liquified Clean Agents and Halons.

The Portagauge® 5 is a multiple echo ultrasonic thickness gauge for measuring thicknesses of various metals and hard plastics, which ignores any coating up to 20mm in thickness.

P/N: 2099382-5

The Permaflow® is a fixed, clamp-on, ultrasonic transit time flow and heat meter that is non-invasive for measuring the flow rates of liquids containing less than 10% of gas/solid contents. It is mains powered, designed for 24/7 monitoring and is accurate to +/- 0.5% of measured value under ideal conditions.

P/N: 3578010-FLOW

Calculate internal pipe pressures using externalnon-invasive and portable flow sensors. To be used alongside the Portasonic 2.FLO® portable ultrasonic flow meter 

P/N: 2618949-CALC


The Portasonic® 2.FL0 is a handheld, clamp on, non-invasive ultrasonic transit-time flowmeter designed to measure flow rates liquids in pipes accurate to +/- 0.5% without requiring any invasive installation. It works on a wide range of liquid types containing less than 10% solid content, and pipes from DN15 – DN2500 made from different metal or plastic materials.

P/N: 2618949-PSO

The Portascanner® AIRTIGHT 520 is Coltraco Ultrasonics’ most advanced ultrasonic room integrity testing tool. It can be used to locate and quantify even minor leak sites quickly, easily, and non-destructively. Records of all of your tests – including images of the test structure with leak sites clearly marked – are stored on the device and can be exported to an external drive at your convenience, all with an intuitive, touchscreen interface.

P/N: 509004-AT520

The Portascanner® 520 is an ultrasonic room integrity testing tool, allowing you to locate even minor leak sites quickly, easily, and non-destructively. The perfect tool for ensuring and maintaining airtight integrity. 

P/N: 509004-520

The most accurate and fast acting constants loss monitoring system of its kind. Capable of detecting a loss of agent mass to within 1% in Inert gas, CO2 and Clean Agent systems, and in addition to weigh loss, will provide accurate percentage pressure loss of Inert gas systems associated with agent contents leakage.

P/N: 2594650-FW

The Portalevel® MINI is a portable and battery powered, liquid level indicator designed to non-invasively, accurately, and reliably measure the level of fire suppression agent contained within a cylinder. The Portalevel® MINI is suitable for most standard size cylinders containing CO2, Liquified Clean Agents and Halons. 

P/N: 2290334-MINI

The Portasteele® CALCULATOR is the perfect partner to any of Coltraco Ultrasonics’ liquid level detectors. It allows you to convert your measured liquid level to an agent weight, precisely and accurately. These readings can then be saved and exported for future reference and traceability. 

Used in partnership with the Portalevel® Ultrasonic Level Indicator range 

P/N: CALC-007

Coltraco Ultrasonics are global leaders in the monitoring of liquefied and non-liquefied gaseous extinguishing systems that protect high-asset value installations and critical national infrastructure.

Comply with ISO 14520:

Portalevel® MAX PLUS
New liquid level indicator for a wide variety of fire suppression agents, such as: CO2, FM200™, NOVEC™ 1230, Halon agents, FE-13™, FE-25™, NAF S III™ and all core Clean Agent systems, accurate to within +/-1.5 mm.

Portasteele® CALCULATOR
Precisely calculate the mass of agent in fire suppression systems to within 1% accuracy using the dimensional data of the cylinder, in combination with the liquid level found using the Portalevel® MAX PLUS.


A unique and innovative contents monitoring solution for pressurised, non-liquified inert gas cylinders such as Inergen™. Portagas® detects marginal changes in the internal cylinder pressure with precision well below 5% demanded by the regulations

Real-time monitoring of agent mass loss and equivalent pressure loss in inert gas, liquified and non-liquified fire suppression systems to 10g, or less than 1% accuracy above 10 kg total cylinder weight.

Portascanner® AIRTIGHT 520
Leak quantification and air flow rate monitoring for compartments containing high-value assets protected by gaseous extinguishing systems. Detect leak sites as small as 0.06mm, with a tolerance of 0.02mm.

The integration of technological solutions offered by the Portalevel® MAX PLUS, Portasteele® CALCULATOR,  PermaMass® FEATHERWEIGHT, Portasonic® 2.FL0 and Portascanner® AIRTIGHT 520 to existing problems application of ISO standards and good global engineering will protect dynamic pressurised systems, the individuals that maintain them, and the structures they are working so hard to guard against fire, delivering our vision of the Safesite™ on land and the Safeship™ at sea.
