Abstract
A method for operating a mass flowmeter that employs the Coriolis principle and through which flows a medium, the flowmeter including a measuring tube through which passes a medium, which measuring tube is stimulated into oscillating and the resulting oscillatory response of the measuring tube is measured includes the step of gauging the pressure of the medium flowing through the measuring tube by evaluating the collected oscillatory response on the basis of a physical-mathematical model for the dynamics of the mass flowmeter. Thus, without requiring any additional devices, it is possible for a Coriolis mass flowmeter, apart from measuring the mass flow, to also measure the pressure in the measuring tube.
