Applications

Heat pump

Heat Pumps

Ultrasonic flow meters optimize heat pump efficiency with low pressure drop, robust design, and advanced features. Integrated heat energy measurement, gas bubble, and glycol detection ensure safety and efficiency without disrupting fluid flow.

Drinking potable water

Potable Water

Ultrasonic flow meters excel in drinking water applications, offering non-intrusive measurements and high accuracy. Ideal for fresh water and flat stations, building monitoring, hydraulic balancing, and hygiene.

Green hydrogen applications

Fuel Cells & Electrolyzers

Ultrasonic flow sensors excel in fuel cell and electrolyzer applications, measuring de-ionized water in cooling circuits. Their full plastic body ensures compatibility.
