Morgan Technical Ceramics ElectroCeramics has launched an ultrasonic sensor which gives accurate gas flow measurement.
The sensors are 20 mm in dia. and can be integrated into acoustic anemometry systems and Smart metering systems for measuring natural gas usage. They are also suited for air-coupled level measurement of liquids and solids, and provide accurate information in one, two, or three dimensions.
The ultrasonic sensors use high-performance piezoceramic materials and have no moving parts. They work by calculating the gas flow as a measurement of time of flight of sound wave through the fluid.
