Background
In order to calculate the cost of sewage treatment or save water, the amount of water to be discharged needs to be measured frequently. Drainage is often done in two ways: one is gravity drainage, namely a drainage pipe channel is provided with a slope in the horizontal direction, and sewage flows along the slope of the pipe channel by virtue of gravity to be drained; the other is pressure drainage, namely, a pump is used for supplying energy to liquid, and sewage is discharged through pipeline transportation. The gravity drainage has the biggest characteristic that the drainage flow rate is large in change from zero to a normal value to a maximum value and is continuously and repeatedly changed, so that a drainage pipe duct cannot be filled with the cross section frequently, and the measurement principle of a common flowmeter requires that fluid passing through the flowmeter must be filled with the cross section of the flowmeter, so that the accurate measurement is possible.
