The flow sensor is located in the measured pipe, and the converter is installed outside the measured pipe. The water flow is detected by the flow sensor, and the internal processor of the converter processes the electrical signal and converts it into a data signal to calculate the water flow. However, when the water flow meter is used to measure kitchen sewage or domestic sewage, large impurities in the sewage can easily block the flow sensor, affecting the water flow through the flow sensor, resulting in large measurement errors.

The sewage then flows into the connecting pipe 1 and is discharged into the external sewage pipe. In the process of the sewage passing through the connecting pipe 1, the water passes through the flow sensor body 2, the flow sensor body 2 detects the water flow, and then processes the signal through the converter 3 to obtain the final water flow data, so that impurities can be removed by filtering. The impurities will not fall on the flow sensor body 2 and be blocked, which is beneficial to the normal operation of the flow sensor body 2 and ensures the detection accuracy of the flow sensor body 2; when cleaning, close the second control valve 8 and the first control valve 4, open the third control valve 11, and make the water pump 13 flow the external water into the flushing pipe 10 through the suction hose 14 and the water inlet hose 12.
