We have a long history and good experience operating in the USA and Canada. We are proud of our relationships with leading navies worldwide, including the US and Canadian.

More than 20 years ago the US Navy’s Naval Sea Systems Command (NAVSEA) purchased 110 Portalevel™ handheld ultrasonic liquid level indicator units. The US Navy ordered through Ascoa Fire Systems to meet their 1/8” accuracy requirement on testing the agent in High Pressure Halon systems.

More recently, we are delighted to announce that Portalevel™ is now in service with the Royal Canadian Navy. The units operate with their Atlantic and Pacific Naval Bases in Halifax and Vancouver.

We congratulate the team and wish the USN and RCN Fair winds and Calm seas.
