What is Ultrasonic Flow Meter?
Ultrasonic flow meter is designed to measure the velocity of liquid within a closed conduit. It uses the well-known transit-time measurement principle, plus our proprietary signal processing and ultrasonic transcribing technologies.
A pair of ultrasonic transducers is mounted on the pipe upstream and down stream respectively. Each transducer serves as both ultrasonic transmitter and receiver. The main unit operates by alternately transmitting and receiving a coded burst of sound energy between the two transducers. The transit-times in the upstream direction as well as in the downstream direction are measured. The difference of the two transit times is directly and exactly related to the velocity and the liquid in the pipe.
