High performance

wrapped arround electrode available

 

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.

 

Application: ultrasonic flow meter sensor

 

Material:  PZT-51 (soft PZT, equal to P-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.
