In 2023, Coltraco Ultrasonics and Viking EMEA joined forces to develop a non-invasive liquid level indicator utilizing ultrasound. It was essential for Viking EMEA that the finished unit would comply with regulations, such as NFPA 2001 clause 5.1.4.5: Where a liquid-level indicator (LLI) is provided as a component of the container assembly, the LLI and method of measuring the agent quantity shall be listed.<\/em><\/p>\n\n\n\nTo ensure that Viking EMEA can offer their customers an ultrasonic liquid level indicator that meets the accuracy requirements of the notified bodies, across the system temperature range, Coltraco and Viking EMEA conducted a test and development series.

This approval also includes a marking done by factory or authorized first fill companies offering VSN 1230 and VSN 200 systems. Copies of the certificates are available from Viking EMEA.<\/p>\n\n\n\n
Coltraco and Viking EMEA are delighted to provide the firefighting market with the first FM approved Non-invasive Ultrasonic Liquid Level Indicator and want to emphasize that only ultrasonic units approved with the firefighting system are eligible substitutes for Mechanical Liquid Level Indicators.<\/p>\n\n\n\n
