Doppler Effect Ultrasonic Flow meter Application:
The Doppler Effect Ultrasonic Flow meter use reflected ultrasonic sound to measure the fluid velocity. By measuring the frequency shift between the ultrasonic frequency source, the receiver, and the fluid carrier, the relative motion are measured.The Doppler flowmeter converts the measured frequency shift into a volumetric flow rate. The velocity of flow in the pipe is calculated using the frequency shift, the original frequency of the ultrasonic signal, the velocity of the sound through the emitter material, and the sine of the angle of the signal into the liquid. Once the velocity is known, the volumetric flow rate can be easily calculated by multiplying the velocity by the area of the pipe.
