METHOD OF MEASURING LIQUID FLOW RATE Russian patent published in 2019 - IPC G01F1/22

Abstract RU 2690714 C1

FIELD: measuring equipment.

SUBSTANCE: invention relates to measurement equipment, namely to measurement of liquids flow rate, and can be used in automated control systems of technological processes in air separation plants. Method of measuring liquid flow rate is based on comparison of measurement result of liquid level in measuring tank with specified value, in accordance with its deviation, adjusting the cross section area of the outlet nozzle and, when the condition h=h_spec, where h is liquid level in measuring tank, h_spec – specified level of liquid, determination of exit nozzle cross-section area and calculation of liquid flow rate.

EFFECT: wider range of measuring liquid flow rate.
