In the embodiment of the present invention, the water level detecting device comprises a pipe 110, a water level detecting ring 120 and a signal processing module 130, wherein the water level detecting ring 120 is arranged around the inner wall of the pipe 110, and the signal processing module 130 is fixedly arranged on the outer wall of the pipe 110; a plurality of detection electrode terminals 121 and an auxiliary electrode terminal 122 are disposed on the water level detection ring 120; the plurality of detection electrode terminals 121 and the auxiliary electrode terminal 122 are respectively connected to the signal processing module 130.

In the embodiment of the present invention, it should be noted that fig. 1 only shows that the water level detection ring is disposed on the inner wall of the pipeline and the signal processing module is disposed on the outer wall of the pipeline, in fact, the water level detection ring may also be disposed on the outer wall of the pipeline, and at this time, the detection electrode end and the auxiliary electrode end need to be adjusted correspondingly, which may be referred to the following description of fig. 2. It is same, the signal processing module also can set up on the inner wall of pipeline equally, however compare in setting up the signal processing module in the pipeline inner wall, set up the signal processing module in the pipeline outer wall, the core structure that can guarantee the device can not receive the corruption of sewage, if set up the signal processing module in the pipeline inner wall, on the one hand need carry out water repellent to the signal processing module, the cost is improved, on the other hand, the signal processing module is relatively bulky, pipeline debris are also more easily because of receiving the hindrance of signal processing module and pile up, influence the circulation ability of pipeline. Therefore, the signal processing module is preferably disposed on the outer wall of the pipeline.
