There are two main types of ultrasonic flow meters: Doppler and transit time. While they both utilize ultrasound to make measurements and can be non-invasive (measure flow from outside the tube, pipe or vessel). Various kinds of ultrasonic flowmeters have been widely used in industrial production, commercial measurement and hydraulic testing.

Ultrasonic Flow Meter Sensor

Material: PZT-51 (equal to PZT-5A).

PZT-51 is a modified SOFT PZT for general purpose. It is dedicated to low aging rate and extremely stable performance requirement etc. transducers and PZT-51 has high sensitivity, permittivity, and time stability in applications when used as the receiver or generator element in accelerometers, vibration pickups, and hydrophones. Applications.
