FIELD: physics.
SUBSTANCE: flow metre includes a drive and measuring sensors connected to a tube. The drive makes the tube vibrate in response to a drive signal. The method involves establishing predetermined voltage of the measuring sensor and measuring temperature of the flow metre. The method further involves generation of temperature-compensated predetermined voltage of the measuring sensor and controlling the drive signal to maintain the temperature-compensated amplitude of vibration of the tube.
EFFECT: ensuring constant amplitude of vibration of the tube at high temperatures.
