Abstract

In order to develop a method for determining a measured value of a target measured variable of a multiphase flow, in particular, of a two-phase flow, wherein a value of a pressure of the multiphase flow is measured as a primary measured variable by means of a measuring device, with which a desired target measured variable of a multiphase flow, for example, the total mass flow can be determined in a simple manner from a primary measured variable, it is suggested in accordance with the invention that a time development of the primary measured variable be measured, the measured time development of the primary measured variable be compared with reference time developments of the primary measured variable, with which a respective reference value of the target measured variable is associated, and the measured value of the target measured variable be determined from the reference values of the target measured variable as a function of the result of the comparison of the measured development of the primary measured variable with the reference developments of the primary measured variable.
