If the water inlet pressure is high, the partial pressure overflow valve increases the flow rate so as to realize the pressure reduction of the water inlet flow rate; if the inlet water pressure is smaller, the partial pressure overflow valve reduces the flow rate so as to realize the supercharging of the outlet water flow rate. The device is convenient to operate, simple in structure, capable of effectively improving flow detection efficiency, improving flow detection precision, and having great practical value, and solves the technical problems that the minimum lift of a booster pump in the prior art is large, and the booster pump cannot perform low-pressure test flow detection.
