Water level monitor device

The utility model provides a water level monitor device, which is suitable for the field of water level control technique. The water level monitor device comprises a high-level and low-level alarm unit; a plurality of water level probes; a first selection switch unit for selecting one of the water level signals detected by the water level probes as the high-level signal, and/or selecting the other one of the water level signals detected by the water level probes as the low-level signal; a high-level and low-level amplification unit for amplifying the high-level signal and/or the low-level signal selected by the first selection switch unit; and a microcontroller for controlling a high-level and low-level alarm unit to send a high-level alarm and/or a low-level alarm according to the amplified high-level signal and/or the amplified low-level signal. The device can bring convenience to the monitoring staff to know whether the water level in the water container is over high or over low. Compared with the conventi
