FLOWMETER OF PERMANENT PRESSURE DIFFERENTIAL Russian patent published in 1997 - IPC

Abstract RU 2082104 C1

FIELD: chemical, oil refining and other industries, measurement of flow rate of gases and liquids by method of permanent pressure differential. SUBSTANCE: flowmeter of permanent pressure differential is composed of cylindrical case 1 with diaphragm 2 which houses float 3 mounted for vertical movement, rigidly anchored on rod 4 and coupled to system 5 of electric differential-transformer transmission of readings. Side surface of float 3 has curvilinear profile and diameter of horizontal section of float changes in height in agreement with mathematical dependence. EFFECT: high-precision measurement of flow rate in wide range. 1 dwg
