Description

technical field [0001] The invention relates to a device for fluid mass flow, and specifically designs a powder mass flow meter. Background technique [0002] At present, in the domestic food industry, pharmaceutical industry, and building material industry, there are various powder mixing processes according to a certain proportion. The ratio is not high, and the approximate ingredients are used. Taking the beverage industry as an example, it is necessary to mix various powder materials such as milk powder, starch, corn flour, monosodium glutamate, aspartame, etc. in the liquid slurry. Measurement, then water-soluble process, the efficiency needs to be improved. Existing powder mass flowmeters mainly come in several forms such as belt scales, loss-in-weight scales, rotor scales, impact flowmeters, and Coriolis flowmeters. Belt scales and rotor scales have low measurement accuracy; weightlessness scales and impact flowmeters have impact and discontinuity in application; i...
