Abstract
The utility model discloses a water level detector which comprises a switch type water level probe, an electric motor, an angle transducer which is connected with the switch type water level probe and used for controlling the lifting of the switch type water level probe, and an RCX program controller which is connected with the electric motor and converts the rotated angle of the gear of the electric motor into digital signals, wherein the input end of the RCX program controller is connected with the switch type water level probe and the angle transducer, and the output end thereof is connected with the electric motor. The RCX program controller judges whether the position of the switch type water level probe needs to be adjusted, leads the switch type water level probe to rise or decline, and judges the rising distance and the declining distance of the switch type water level probe according to the digital signals obtained by conversion of the angle transducer, thereby obtaining the depth of the level of conductive liquid. The water level detector has the beneficial effect of being capable of mastering the rising and declining condition of underground water level in real time.
