FIELD: physics.
SUBSTANCE: proposed transducer comprises vibrator, excitation and oscillation picking-up electromagnetic transducers arranged on vibrator and amplifier to make self-oscillatory circuit, as well as converter and recorder Note here that vibrator is arranged inside housing with inlet and outlet holes. Said vibrator is made up of two aligned different-diameter tubes to make closed mechanical oscillatory tonometer-type system. Top and bottom bases of tubes are jointed together by means of top and bottom shaped bushes. Excitation and oscillation picking-up electromagnetic transducers are screwed in vibrator outer tube at equal distance from top and bottom bases of vibrator outer tube. Amplifier input is connected to oscillation picking-up electromagnetic transducer while its output with excitation electromagnetic transducers is connected via electronic gate with converter. Converter output is connected to recorder to display measured medium flow rate.
EFFECT: higher accuracy, operation reliability and resistance to ionising radiation.
