This Paper is an introduction about Liquid level detecting system of tank, Especially, in order to detect liquid level of tank, we install a magnetic float in the pipe for detecting of tank, and the detecting device equipped hall sensor is moving upwards and downwards according to the surface of the pipe, detecting magnetic force of interior of the pipe, and it transformed to current value and transmitted to the PLC. so we can know the level in real time. Afterward, I think this device will be adapted to varies fields.
