Ultrasonic Flowmeters

The ultrasonic gas flow meter uses sound waves to establish the velocity of gas flowing in a pipe. At no-flow conditions, the frequencies of an ultrasonic wave transmitted into a pipe and its reflections are the same. Whereas, when gas flows, the frequency of the reflected wave changes because of the Doppler effect. When gas moves faster, the change in frequency increases linearly. The meter’s transmitter processes the signals from the transmitted waves and their reflections to determine the gas flow rate.
