Water level detecting device free of contact with water

The utility model provides a water level detecting device free of contact with water. The water level detecting device comprises a water container and water gauges arranged outside the water container. The water level detecting device is characterized in that at least one conductor clamp is arranged outside the water gauges and connected with a circuit board, the lower end of each water gauge is communicated with the container through a guide pipe, and the change of the water level is recognized by detecting the difference value of the quantities of electric chargers in the water gauges; a concave portion is arranged in the middle of each conductor clamp, the conductor clamps clamp the water gauges and are tightly attached to the water gauges, an inserted piece is arranged at the joint between each conductor clamp and the circuit board, and insertion holes are formed at corresponding positions of the circuit board; the conductor clamps are distributed in the vertical direction of the water gauges, and the water level needing to be set can be detected. By the adoption of the water level detecting device, instruments will not be in contact with a water source during detecting the water level, so that pollution to the water quality is avoided; the water level detecting device free of contact with water is accurate in detection, simple and reasonable in structure, convenient to operate, safe and reliable.
