The principle and method of controlling the float valve to control water by frequency converter

First, the float ball level controller float ball switch principle is as follows

The liquid has buoyancy, and the float system (generally with corresponding auxiliary equipment) is made according to the buoyancy of the liquid. When the liquid level rises, the float system also rises accordingly.

Similarly, when the liquid level drops, it also drops accordingly. When it rises or falls to the set position, the float system will encounter the travel switch (or other microelectronic device) at the set position.

Thereby, the travel switch emits an electrical signal, and the electronic control device acts immediately upon receiving the electrical signal, and cuts or turns on the power to form an automatic control system.

Second, the inverter controls the float ball valve to control the water

The float switch is actually equivalent to a liquid level measurement switch to judge the water level. When the water level is low, the inverter can be started to control the water supply of the pump; when the water level is higher than a certain value, stopping the inverter means stopping the pump. To put it bluntly, the inverter is equivalent to a soft starter, because the float switch is only a switch, and it is better to connect the switch contacts to the enable of the inverter.
