The float liquid level gauge is mainly composed of magnetic float ball, sensor and transmitter. When the magnetic levitation ball floats up and down along the conduit with the change of liquid level, the magnetic steel in the floating ball attracts the dry reed at the corresponding position in the sensor to change the total resistance (or voltage) of the sensor, and then the transmitter converts the changed resistance (or voltage) signal into 4-20mA current signal for output
