measurement of mass flow rate. SUBSTANCE: flowmeter includes two flow tubes, exciter of vibration of tubes with phase shift of one relative to another, transducers detecting displacement of tubes as result of flow of material through them. Each transducer has pair of magnets put on flow tubes and coil placed near magnets. Coil is kept in fixed position on flow tubes with reference to magnets with the aid of two laminated springs. In agreement with another variant flat coils of transducers are positioned on printed circuit boards. EFFECT: increased measurement accuracy thanks to exclusion of vibration of coils of exciter of vibration and transducers put on flow tubes. 12 cl, 11 dwg
