C61F-GP liquid level controller working mode and principle: match with water level switch. Put one water level switch in high water level A position and another water level switch in low water level B position. When the water reaches the B position, the relay closes, at this time you can control the start of the pump or solenoid valve, start to feed the water;
When the water rises to reach the high water level A position, the relay breaks, the pump or solenoid valve is disconnected. Then the water goes to the low water level B position, and the cycle keeps repeating.
Expanded Information:
Liquid level controllers are mainly used to monitor the level of the tanks to realize the upper and lower limits. Alarm or monitor the presence of liquid in the pipeline, the tank material can be various types of metal, metal or non-foaming plastic.
This way is not affected by medium density, dielectric constant, electrical conductivity, reflection coefficient, pressure, temperature, precipitation and other factors, so it is suitable for pharmaceutical, petroleum, chemical, electric power, food and other industries of all kinds of liquid level engineering control, for toxic, strong corrosion of hazardous liquid detection, the product is the ideal choice. Belong to the high-grade products, the price is not expensive.
The float of the level controller is susceptible to external debris affecting its stability, especially fibrous debris entanglement and errors, the same small tank should not be used more than one, otherwise it will phase entanglement.
Relatively short service life, and most of the direct connection to 220V, there are certain security risks, one day because of broken wires and leakage electrician. So the power cord of the float switch is a complete part of the device, once the wire is found to be damaged, the device should be replaced, not allowed to repair the wire.
