Abstract (en)
[origin: WO2021121970A1] The invention relates to a method (100) measuring the flow of a liquid medium having variable gas content, on the basis of a differential-pressure measurement by means of a differential-pressure-generating primary element, through which the medium flows, which method comprises: ascertaining a differential-pressure measurement value (110) between two measurement points of the differential-pressure-generating primary element; ascertaining a flow regime (120); ascertaining a flow rate measurement value according to the differential-pressure measurement value and the flow regime (140), the flow rate measurement value being ascertained by ascertaining a provisional flow rate measurement value on the basis of the differential-pressure measurement value under the assumption of a first flow region, which provisional flow rate measurement value is corrected if a second flow regime different from the first flow regime is determined.
