FIELD: chemical and petroleum industries. SUBSTANCE: flowmeter designed for metering flowrates of chemically active liquids in large quantities has measuring flow section in the form of large- diameter ceramic pipeline ( 100 mm) that mounts polarizer and analyzer magnets, modulating and recording coils for flowmeter signal, as well as detector, and data processing and display device. Measuring section is assembled of butt-joined annular members not deformed during annealing, their inner diameter corresponding to flow section of delivery pipeline. Alumina ceramic annular members are interconnected at mating points through threaded joint which is sealed with nonmagnetic nonconducting enamel. EFFECT: improved measurement accuracy under high pressure and temperature conditions. 3 cl, 3 dwg
