FIELD: measurement equipment.
SUBSTANCE: invention solves the task of continuous determination of mass flow rate of fluid medium in wide range of densities and speeds. The device for determining mass flow rate of fluid media includes a sensing element with an electric signal sensor and a signal processing unit. As a measuring element of dynamic action of fluid medium there used is an elastically bent blade that oscillates at proper frequency. On the blade there fixed are strain gauges of resistive type, the signals from which are added to a measuring circuit of integral deflection and oscillation frequency of the blade.
EFFECT: higher reliability, easy operation and wider dynamic range of accurate measurement of mass flow rate of flowing media.
