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, a piezoelectric transducer is placed on the tube wall and transmits ultrasonic waves into the liquid perpendicularly to the direction of the flow. The frequency shift between the transmitted and received ultrasonic waves is evaluated and the velocity of liquid in a pipe is determined.
Applications
- Piezoceramic transducers produce ultrasonic signals for the measurement of the 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
