MASS TURBINE FLOWMETER Russian patent published in 2002 - IPC

FIELD: measurement technology. SUBSTANCE: mass turbine flowmeter includes two screw turbines with different pitches of helical l line intercoupled by moment-forming unit located in tight dividing enclosure and two units to pick off signal. Screw turbines are mounted in body for rotation. Momentforming unit comes in the form of at least two link mechanisms, each carrying L- shaped weight put with one end on axle of first turbine eccentric to axis of flowmeter for turn and linked with the aid of tie-rod, fork and flexible coupling to second turbine. EFFECT: increased measurement accuracy of volumetric flow rate and density, raised reliability. 6 dwg
