Ball Float Type Level Switch

The Ball Float Type Level Switch is a contact type level switch independently developed by our company, which is more cost-effective than the tuning fork switch. Liquid level float switches are usually threaded or flanged, it can be installed on water tanks , fuel and other oil tanks .

What’s the working principle of ball float type level switch?

Magnetic float ball level switch consists of three parts: magnetic float ball, sensor and transmitter. When the magnetic float ball changes with the liquid level and floats up and down along the conduit, the magnetic steel in the float ball attracts the reed switch at the corresponding position in the sensor, thus the total resistance (or voltage) of the sensor changes, and then the stainless steel float level controller makes the changed resistance (or voltage) signal to convert into a current signal output of 4-20mA. The upper and lower limit alarms can be set on the display instrument to realize the position control of the liquid level too .

What are the advantages of WEpower’s float ball level switches?

  The ball float type level switch has good reliability and high precision; in addition to the on-site indication, it can also be equipped with a remote transmitter, an alarm switch. The measurement accuracy of the ball float level switch can reach ±5mm, and the maximum temperature can reach 200°C.
