In this way, the air between the water level sensor and the control device is communicated, and the cavity 13 of the control device is ventilated up and down, so that the pressure in the water level sensor is balanced with the atmospheric pressure, and the measured value is closer to the actual value.
In this embodiment, the controller is a PCB board. An algorithm is preset in the controller, and the algorithm is subtraction and is a conventional calculation program. The calculated water level result obtained by the final calculation is the difference between the length of the air line 6 and the water level information measured by the water level sensor 2, that is, the water level result is the distance from the water level of the liquid in the water level pipe 4 to the opening of the water level pipe 4.
