METHOD OF CALIBRATION AND CHECKING OF GAS FLOWMETER Russian patent published in 1998 - IPC

Abstract RU 2121137 C1

FIELD: measurement technology. SUBSTANCE: method is based on gas passing through flowmeter, on measurement of gas passing time and pressure variation in tank at constant temperature and on determination of flow rate by means of values obtained. Gas after it passes through flowmeter, is delivered to tank. In this case, supercritical differential pressure is maintained between flowmeter and tank. EFFECT: simplified operation. 1 dwg
