Summary

UQD Ball Float Level Transmitter consists of measurement part and signal controller part. According to structural features, the measurement part can be divided into 90 type with small angle, 91type with big angle, 92 type with external float. The signal controller part can be divided into analog type (UQD.A) and intelligent type (UQD.Z).They are perfect instruments for liquid level measurement in production process in petroleum, chemical, metallurgy, power industry and so on. 

 

Operation principle

The measuring unit of UQD ball float level transmitter includes floating ball, balance lever, balance weights, these three elements comprise a torque balance device. The floating ball can float up and down freely by level changing. When the level changes, the floating ball position changes correspondingly and drive the shaft to rotate through connecting rod of the floating ball. The angular displacement sensor in the controller couples with the shaft via a pair of gears. In this way, the changes of level can be converted into electric signal that will be turned into standard current signal in direct proportion by the electronic circuit in the case.
