The most common is to measure the water level before and after the coarse grille and the fine grille at
the water inlet of the sewage treatment plant to calculate the height difference between the water
levels. There are also installations before and after the gate, measuring the water level difference
before and after the gate to determine the time to open the gate.
Ultrasonic level difference meter (material level, liquid level) is used to measure the difference
between the liquid level or material level of two different containers.
There is also not to measure the liquid level difference, but to measure the water level of the two pools,
and then output 2 4-20mA.
