FIELD: test-and-measurement technology. SUBSTANCE: flowmeter has a non-magnetic housing, sensitive element, electromagnetic displacement sensor located on the surface of the housing and composed of an exciting winding and two measuring windings disposed on opposite sides relative to the exciting one; permanent magnet. The accelerometer is characterized in that a layer of magnetic liquid is used as a sensitive element located on the inner surface of the housing where field of permanent ring magnet disposed over the exciting winding acts. EFFECT: enhanced accuracy. 1 dwg
