Power Generation

Coltraco Ultrasonics have been proudly serving the Energy Industry for 30 years. We supply instrumentation and systems, across the Power Generation sector to Power Plants, coal fired power stations, hydro gas plants, nuclear power plants.

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 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 PORTATANK® is a non-invasive ultrasonic liquid level indicator capable of detecting liquid levels in a huge range of applications on virtually all liquid types from small 15 cm diameter AFF mechanical foam extinguishers, clean agent fire suppression systems, oil levels in Transformers and  Ring Main Units (RMU) all the way up to 15 m diameter industrial tanks.  Our most versatile liquid level indicator to date providing advanced diagnostics through a supplementary handheld oscilloscope included with every unit. Portable, durable and hand-held, the Portatank® offers greater flexibility when testing a range of applications, operated by one person with no installation cost.

P/N: 3141184-TANK

The Portalevel® INTRINSICALLY SAFE is an ultrasonic liquid level indicator approved for Zone 1 ATEX hazardous or explosive environments.

P/N: 2290334-IS

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

Ensure customers in the Power Generation, Electricity & Gas Distribution markets are protected from the risk of fire 24/7, and that business continuity is assured.


Ultrasonic tank liquid level indicator, capable of detecting liquid levels from side walls of tanks from 0.5 – 15 metres wide. It works on a wide variety of tank wall materials, wall thicknesses and virtually all liquid types without any installation requirements. By using the Portatank, users can quickly check form the outside of the transformer, if all the oil is at the correct level inside and thus if it is safe to open. Just a few seconds test can drastically reduce the risk to maintenance crews


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.

Customer examples are:

  • Vestas Wind Systems A/S
  • Conoco
  • Total
  • Saudi Aramco
  • Chevron (CVX)
  • CenterPoint Energy Houston Electric, LLC
  • Dungeness B
  • Sellafield

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.
