Main Features of Level Control Switch


  • Use the microswitch to make contact output, and the contact capacity of 10A / 250VAC can directly start the motor equipment.

  • The European standard (HAR) rubber cable of cable float level switch has good weather resistance, low price and long service life.

  • The structure is simple, no maintenance is needed, and sewage and clean water can be used.

  • The length of cable ≦ 20 meters can be customized.


In water treatment, a liquid level control switch is often related to the safety, economy, and feasibility of the entire process.


There is also another type of liquid level float switch that uses a mercury switch as a contact output. When the liquid level rises and contacts the float, the float changes with the water level rise angle centered on the weight. When the rising line angle exceeds 10 ° above the water surface, the floating water level indicator will have an ON or OFF contact signal output. We are a float type level switch manufacturer with side mounted float level switch, mini float level switch, and cable float level switch for your choice. Welcome to get a quote!


Level Switch


Liquid Level Switch in A Water Treatment Process


There are generally raw water, intermediate water tank, product water tank, backwash water tank, and even waste liquid tank. The volume is large or small. Generally, the production water tank and the original water tank are relatively large, especially in large production lines. At this time, the float level switch for water tank is often required to control multiple liquid levels in the water tank. Each liquid level corresponds to a different action. Common ones include the start and stop of pumps and the start and stop of produced water. Although some water tanks are large, they do not necessarily require multiple level switches.

FEEJOY is an industrial instrumentation manufacturer that committed to offering all kinds of level switches for volumetric measurement in the industrial process such as water, gas, or other liquid.
