The invention relates to the field of flowmeter verification, discloses a dynamic grid-based self-circulation trough body experiment platform for acoustic flow measurement, and aims at solving the problem that the flows cannot be effectively detected in the prior art. The platform comprises a constant-level water tank, a current plate group, a trough body, a pumping water tank, a circulating waterpump and a dynamic grid-based flow measurement system, wherein the flow measurement system comprises an ultrasonic transducer group, a microcontroller, a water level monitoring device and an automatic lifting device; ultrasonic transducers are arranged on the automatic lifting device; and the ultrasonic transducer group, the water level monitoring device and the automatic lifting device are respectively connected with the microcontroller. Based on the prior part, the platform is provided with the dynamic grid-based flow measurement system, so that the flow speeds in the grids are reconstructed through dynamically adj
