VIKING EMEA and Coltraco Ultrasonics partner on a custom ultrasonic liquid level indicator
Coltraco and Viking EMEA are delighted to provide the firefighting market with the first FM approved Non invasive Ultrasonic Liquid Level Indicator
Portalevel® LITE is Coltraco Ultrasonics’ latest innovation in ultrasonic liquid level measurement, offering high-accuracy performance at an exceptional value. Building on the success of the Portalevel® Original and Portalevel® Mini, it is designed for the non-invasive measurement of fire suppression system contents.

Portalevel® LITE quickly and accurately determines the liquid level in a wide range of liquefied fire suppression agents, including CO2, FM200™, and NOVEC™1230. The device features a high-contrast OLED display that clearly indicates the cylinder contents phase, showing either “GAS” or “LIQUID.”
With over 30 years of experience in developing ultrasonic liquid level indicators, Coltraco Ultrasonics is a leader in this field. Portalevel® LITE uses advanced signal processing techniques to deliver liquid level accuracy to within ±1mm of the true level. Our instruments are crafted to the highest standards in the UK using premium materials, offering superior value and reliability, backed by our unique position in research and development.

The combination of the Portalevel® ADVANCED and Portasteele® CALCULATOR uses our decades of experience in ultrasonic engineering and collaboration with fire suppression system manufacturers to allow a user to clearly determine the agent weight from the liquid level without having to physically weigh the cylinder. The benefits of this are:


Tracebility: The liquid level found is traceable to the agent weight which is the only documented evidence of fire suppression cylinder contents from the manufacturer
Temperature Correction: Any fluctuations in liquid level as a result of temperature changes is automatically accounted for in the calculations, giving you the true agent contents at all times regardless of temperature
All measurements are saved and recorded with time & date stamp, for effectively audit trail and to comply with relevant ISO and NFPA regulations where agent weight is required to be reported
