FIELD: measuring equipment.
SUBSTANCE: method for determining the mass flow value and a vibration flow meter for implementing such a method are provided. The method for determining the mass flow value includes calibration of the vibration flow meter sensor at the first temperature; passing through at least one flow meter pipeline of a fluid having a second temperature that differs from the first temperature; recording vibrations of at least one flow meter pipeline; entering the fluid density value into the electronic flow meter instrument. The compensated value of the mass flow rate of the fluid is determined using an electronic meter, and the elastic modulus of the flow meter sensor remains unknown and is not used by the electronic meter.
EFFECT: possibility of maintaining the accuracy of the flow meter, calibrated at standard room temperatures, when working with cryogenic liquids.
