Overview
Enviro Testers Ultrasonic Liquid Flow Meter for measuring liquid surface, usually install on the top of liquid level. Firstly, the sensor emits ultrasonic wave to the liquid surface. Secondly, wave reach to the liquid level and is reflected, sensor receive the echo for processing. Thirdly, the microprocessor will calculate difference of time between ultrasonic emission and receiving, then convert to distance between sensors to the liquid.
