METHOD FOR PERIODIC MEASUREMENT OF CONTINUOUS FLOW OF LOOSE MATERIALS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2019 - IPC G01F1/76 

FIELD: technological processes.

SUBSTANCE: invention relates to measurement of bulk materials consumption and can be used in technological processes of chemical, metallurgical, food and pharmaceutical industries, as well as in industry of construction materials and agricultural industry. Invention consists in fact that from constant volume of constant volume built into vertical section of pipeline, along which loose material continuously passes, air is periodically evacuated, as a result of which rarefaction is created in reservoir and it is filled with material. Consumption of material is determined from the value of time interval from the moment of beginning of filling to its end, at that moment of filling completion is determined by abrupt increase of rarefaction in air duct above filter, through which air is pumped.

EFFECT: increased reliability, increased accuracy of measurement of loose materials consumption, including those having increased moisture content.
