FIELD: physics, measurement.
SUBSTANCE: flow receiver being part of induction magnetic flowmeter, contains electrononconductive measuring pipe mounted on interior adjoining fluid, two electrodes on measuring pipe for evaluation of electric pressure induced in fluid. Flow receiver magnetic field system on measuring pipe includes two saddle pole coils and two pole ferromagnetic pieces designed as saddle-shaped sheet. To control magnetic field surrounding measuring pipe two ferromagnetic reverse action devices shaped as pipe-covering rings mounted up the flow stream and with flow stream from both pole coils are used. Pole pieces are magnetically connected to reverse action devices with ferromagnetic binders each of which has one sulcate protector covering the first or second winding section of proper pole coil. Receiver is compact in effective axial magnetic insulation.
EFFECT: provided high measurement accuracy for pipes of major diameters(350 mm - 600 mm).
