The invention relates to a high-precision impingement plate flowmeter which comprises a blanking box, an impingement plate mechanism, a measuring mechanism and a correcting mechanism. A feeding port is arranged in a top of the blanking box, a discharging port is arranged in a bottom, the impingement plate mechanism is arranged in the blanking box, and the impingement plate mechanism is connected with the measuring mechanism and the correcting mechanism. The impingement plate mechanism comprises an impulse plate, a support seat, a platform, a stand column and a first rotating unit. The measuring mechanism comprises a push rod, a second rotating unit, a third rotating unit, a force measuring sensor and a blocking seat. The correction mechanism comprises a laser unit, an angle interference unit and an angle reflection unit. A deflection angle is measured through the correction mechanism and is integrated with a measurement structure of the measurement mechanism, an accurate actual impulseis obtained, measurement precision is greatly improved, and the flowmeter is worthy of vigorous popularization.
Description
technical field [0001] The invention belongs to the technical field of metering equipment, and in particular relates to a high-precision punching plate flowmeter. Background technique [0002] In industrial production, it is often necessary to dynamically and continuously measure the powder or fine bulk materials conveyed in the process, so as to achieve the purpose of precise quantification and control of powder or fine bulk materials. The existing punching plate or sliding plate flowmeter has the characteristics of simple structure and fast response, but due to structural defects in the force measuring mechanism and force sensing method, the measurement results deviate from the actual results. Contents of the invention [0003] The object of the present invention is to provide a high-accuracy and high-precision punching plate flowmeter in order to solve the above problems. [0004] The present invention achieves the above object through the following technical solutions...
