TRANSDUCER OF CENTRIFUGAL FLOWMETER Russian patent published in 2003 - IPC

FIELD: measurement technology, measurement of flow rates of liquids, especially low flow rates. SUBSTANCE: transducer has case in which bore core with central conduit is made interference fit in bushing. Walls of screw thread on outer surface of core and inner surface of bushing form helical conduit. Measurement holes coupled to differential manometer are made in pairs in walls of bushing and core opposite one another in middle turn of conduit. EFFECT: increased accuracy of measurements thanks to use of collapsible structure ensuring possibility of its cleaning from fouling. 1 dwg
