Abstract

FIELD: physics.
SUBSTANCE: invention generally relates to flow meters, particularly to Coriolis flow meters. Coriolis flow meter has an exciter which causes tube oscillations, a first sensor configured to generate a first sensor signal which characterizes movement of the tube at a first location, and a second sensor configured to generate a second sensor signal which characterizes movement of the tube at the second location. First and second locations are located so that phase shift between the first and second signals, when the tube oscillates by the exciter, is connected to mass flow rate of fluid medium through the flow meter. Digital signal processor includes a plurality of detectors tuned to a plurality of different frequencies. Detectors are made with possibility of parallel analysis of the first sensor signal and generation of output signal characterizing how accurately actual frequency of the first sensor signal coincides with frequency, on which the corresponding detector is set.
EFFECT: technical result is higher accuracy.
