Ultrasonic Level Meter is non-contact ultrasonic instrument for measuring liquid surface.


ULM usually install on the top of liquid level:

1) The sensor emits ultrasonic wave to the liquid surface.

2) Wave reach to the liquid level and is reflected, sensor receive the echo for processing.

3) The microprocessor will calculate difference of time between ultrasonic emission and receiving, then Convert to distance between sensors to the liquid.

4) Calculate liquid level through height of tank minus the empty distance (Level = tank height – empty distance)


ULM liquid-level meter adopts ultrasonic principle to measure the liquid level. Non-contact measurement, effective anti-interference, easy to install, maintain and use.
