Non-full pipe electromagnetic flowmeter for sewage flow measurement

The invention provides a non-full-pipe electromagnetic flowmeter for sewage flow measurement, which comprises a conduit and electrodes, and further comprises electrode sewage disposal devices, and each electrode is correspondingly provided with one electrode sewage disposal device. The electrode cleaning device comprises a push rod movably inserted in the conduit, a telescopic driving mechanism for driving the cleaning end of the push rod to be close to or far away from the electrode, and a rotary driving mechanism for driving the push rod to rotate to clean the electrode; the mud position detection device comprises sensing probes, the sensing probes are arranged in a fluid flowing area on the inner wall of the guide pipe, the sensing probes are evenly distributed in the circumferential direction of the guide pipe, the conductivity of the corresponding site is detected through the sensing probes, and the mud position site is determined according to the change of the conductivity of each site.
