Abstract
A method for monitoring flow of a medium by means of a pressure difference measuring device and a Coriolis mass flowmeter having two oscillators, which comprise, in each case, a bent measuring tube pair, which are arranged on top of one another and connected for parallel flow between the two pressure measuring points of the pressure difference measuring device, comprising steps as follows: Registering a pressure difference between the first pressure measuring point and the second pressure measuring point; registering a first density measured value based on at least a first oscillation frequency of the first oscillator; registering a second density measured value based on at least a second oscillation frequency of the second oscillator; ascertaining a flow measured value based on the pressure difference, when a difference between the first density measured value and the second density measured value is less than a density difference limit value.
