Gas Metering Without Moving Parts
Replacing a diaphragm with a timing measurement across the duct.
A diaphragm gas meter measures by displacing volume, which means moving parts that wear and a pressure drop that the network pays for. An ultrasonic gas meter times the wave across the channel instead, in both directions, and computes flow from that difference together with the channel length and installation angle.
The result is non-contact measurement, low pressure loss, a wide range ratio and strong corrosion resistance, adapted to gases such as natural gas and air. Industrial gas metering, HVAC fresh air systems and energy monitoring are the named application scenarios for our 200 kHz transducer.
