float level controller-Magnetic ball float liquid level transmitters have the magnetic ball float as their measuring element. Through magnetic coupling, the ball makes the resistance inside the transducer changes lineally. Then the transducer converts the resistance change into 4-20mA standard current signal and output it. In this way, the transmitter can fulfil automatically checking, controlling and recording. It is suitable for liquid level measurement for different kinds of atmospheric vessels and pressurized containers in petroleum, chemical, power, light industry and pharmaceutical industrial field. It is ideal liquid level instruments for underground storage tanks. It can be classified into side mounted type and top mounted type.

Structure principleUQZ series magnetic ball float liquid level transmitter is composed of liquid level sensor and current converter the two parts. The ball float moves with liquid level synchronously to control the dry reed pipe to be on or off so as to make the value of the inner resistance change linearly. Then the current converter changes the resistance value changes into 4-20mA standard current signals and transmits them out.
