PRESSURE TRANSDUCER FOR FLOWMETER Russian patent published in 2000 - IPC

FIELD: measurement of flow rate of polluted fluid media in pipe-lines having large cross-sections. SUBSTANCE: pressure transducer has case with flange for connection to pipe-line and member creating pressure differential that comes in the form of at least one slot-shaped radius conduit with pipe unions for pressure tap. Cross-section of each conduit in longitudinal direction along flow is constant or varies with formation of diffuser and contraction. Member narrowing cross-section of conduit and overlapping width of conduit can be built in each radius conduit. EFFECT: decreased energy losses of flow, enhanced measurement accuracy in fluid media carrying large inclusions of solid particles. 8 cl, 49 dwg
