The frequency converter of the water pump automatically supplies water, but the water pump cannot stop. What is going on?

There are two reasons: the first possibility is that the water pump inverter does not have a sleep function; the other is that the water pump inverter itself has a sleep function, but it has not been set properly. As long as the sleep function is set, when the water consumption is low or no water is used, the inverter will automatically stop the water pump, but when water is needed, the pump motor will automatically turn on to realize automatic water supply. This function can also be extended. The service life of the water pump can also save energy and electricity.

Correct wiring method of liquid level sensor

Correct wiring method of liquid level sensor

Liquid level sensor (hydrostatic level gauge/liquid level transmitter/liquid level sensor/water level sensor) is a pressure sensor that measures liquid level. The static pressure input liquid level sensor (liquid level gauge) is based on the principle that the static pressure of the measured liquid is proportional to the height of the liquid. It is an electrical signal, which is then converted into a standard electrical signal (usually 4~20mA/1~5VDC) after temperature compensation and linear correction.

How the liquid level sensor works

How the liquid level sensor works

Using the principle of static pressure measurement: when the liquid level transmitter is put into a certain depth in the measured liquid, the pressure formula on the liquid surface of the sensor is: Ρ=ρ.g.H+Po In the formula: P: transmitter The pressure on the liquid surface ρ: the density of the liquid to be measured g: the local acceleration of gravity Po: the atmospheric pressure on the liquid surface

What types of liquid level sensors are there? In which fields is it applied?

1. Photoelectric liquid level sensor Photoelectric liquid level sensors are divided into: integrated single-point photoelectric liquid level sensor (contact type), integrated multi-point liquid level sensor (contact type), split type liquid level sensor (non-contact type), pipeline photoelectric liquid level sensor, Stainless steel level sensor.
