Liquid level

Liquid level refers to the level of the liquid in the sealed container (pool) or open container (pool).

The liquid level measurement is divided into two categories: continuous measurement and position measurement.

Continuous measurement: continuously measure the change of liquid level, and the instrument that can realize continuous measurement has liquid level gauge or liquid level transmitter.

Position measurement: A specific position such as detecting whether the liquid level reaches the upper limit or lower limit is called a position measurement. The instrument that can realize the position measurement has a liquid level switch. In the water treatment, the upper, middle and lower liquid levels of the liquid level are used to control the opening or closing of the lift pump and the liquid level alarm.
