Flow Meters

Being the major piezoceramic supplier in Taiwan, Unictron’s piezo elements are the perfect solution for the generation of stable and reliable ultrasonic wave needed in flow meter applications. Our engineering teams have been working in piezo ceramic industry for more than 25 years. We have sound background in materials formulations and ceramic processing technologies as well as advanced characterization and manufacturing facilities for the development and mass production of piezoceramic elements. High performance, high reliability piezoceramic discs and rings with various dimensions are available to meet your demands.

An ultrasonic flow meter can be used to measure the flow rate of a liquid passing a predetermined point in a pipe. As a measuring method that will not disrupt the liquid flow, piezoelectric transducer is placed on the tube wall and transmits ultrasonic wave into the liquid perpendicularly to the direction of the flow. The frequency shift between the transmitted and received ultrasonic waves is evaluated and velocity of liquid in a pipe is determined.

Applications

  • Piezoceramic transducers to produce ultrasonic signal for the measurement of flow rate of liquid in a pipeline where direct contact of the liquid is a concern.

Characteristics

  • Excellent frequency stability
  • Low power consumption
  • High reliability
