However, foreign matter contained in various sewage flowing in the sewage pipe was collected in the band supporting and fixing the flow sensor and the flow sensor, which impeded the problem of preventing the flow of sewage through the sewage pipe or accurately measuring the flow of sewage. In addition, it is not only cumbersome to install a belt for supporting and fixing the flow sensor in the sewer pipe, but also when the flow sensor is not fixedly installed, there is a problem that the expensive flow sensor is lost or lost. In addition, to fix and support the flow sensor by fixing bolts on the inner surface of the sewage pipe, the sewage pipe is damaged or lost, and the function of the sewage pipe is reduced, and the sewage penetrates into the soil through the broken gap of the sewage pipe. Problems such as soil pollution were also inherent.
