The invention provides a flowmeter detection platform. The flowmeter detection platform comprises a liquid storage tank, a valve bank and a measuring cup; the upper end of the liquid storage tank is provided with an inlet valve; a flowmeter to be detected is arranged between the liquid storage tank and the measuring cup; the liquid storage tank is connected with the flowmeter to be detected through a guide pipe; the guide pipe positioned between the liquid storage tank and the flowmeter to be detected is provided with the valve bank; the flowmeter to be detected is connected with the measuring cup through a guide pipe. The flowmeter detection platform has the beneficial effects that the flowmeter detection accuracy is improved, the accuracy of the flowmeter to be detected under the velocity varying condition can be detected, liquid can be repeatedly utilized, the accuracy of the flowmeter to be detected can be quickly and efficiently detected, the accuracy of the flowmeter to be detected under the vibration condition can be detected, and the flow condition of the liquid in the detection process can be observed.
