SCREENED ELECTROMECHANICAL DEVICE AND MASS FLOWMETER OF CORIOILIS TYPE (VARIANTS) Russian patent published in 1998 - IPC

FIELD: instrumentation engineering. SUBSTANCE: screened electromechanical device provides for bilateral conversion of mechanical and electrical energy. It has winding assembly coupled to its far end and magnetic assembly coupled to its near end. Magnetic assembly is intended for interaction with winding assembly. Winding and magnetic assemblies are surrounded by screening assembly designed to reduce magnetic field outside the above-indicated screening assembly. Mass flowmeter has support and continuous loop of pipe line secured reliably to support at its inlet and outlet ends. Loop is exposed to effect of drive screened electromagnetic device which oscillates loop near oscillation axis. Sensor is designed to measure values of Coriolis forces arising as a result of oscillatory motion to which mass flow in loop section is subjected. EFFECT: more effective construction. 25 cl, 6 dwg
