200Khz Ultrasonic Gas Flow Sensor
200Khz Ultrasonic Gas Flow Sensor. – What is Gas Flow Meter? A gas meter is a specialized flow meter, used to measure the volume of fuel gases such as …
The principle of the gas flow sensor lies in the fact that when ultrasonic waves propagate in an air/liquid medium and encounter impurities/interfaces, there will be significant reflection, resulting in a reflected echo. The speed is calculated by comparing the time difference of the signal’s propagation in the fluid.
