Problems solved by technology
[0002] The solid flowmeter is used to provide continuous online load-bearing measurement for flowing dry bulk materials such as sand. Its principle is to use the momentum principle to detect the weight of falling solid materials such as block, granular and powder. The meter uses moving parts, and the external vibration has a great influence on the measurement. If the environment is harsh, the material will stick to the detection plate, which will affect the measurement accuracy.

The invention relates to the field of electronic flowmeters, in particular to a plate-type solid electronic flowmeter for on-line measurement of the flow and accumulation of free-falling loose solid materials. It includes a shell, a diversion groove, a detection plate and a force measuring device, wherein the detection plate is placed obliquely in the casing, the upper end of the detection plate is hinged on the rotating shaft, and the lower end is a free end; the diversion groove is set on the upper end of the The plates are connected; the force-measuring device is placed behind the bottom of the test plate, and the force transmission rod of the force-measuring device is perpendicular to the bottom of the test plate. The invention has simple structure, no running parts, adopts beam type force sensor and installs it externally. The detection board has good stability, strong impact resistance, little impact on detection due to vibration, and can work under harsh environmental conditions.
