Mass flow rate calculation method

A method for calculating the mass flow rate of one or more phases in a multiphase flow comprises; using a Coriolis meter to measure the apparent bulk density of the multiphase flow 60; calculating a first apparent void fraction (VF) using the apparent bulk density 70; using a microwave meter to meas...

Zusammenfassung:	A method for calculating the mass flow rate of one or more phases in a multiphase flow comprises; using a Coriolis meter to measure the apparent bulk density of the multiphase flow 60; calculating a first apparent void fraction (VF) using the apparent bulk density 70; using a microwave meter to measure the permittivity of the multiphase flow 80; calculating a second apparent VF using the permittivity measurement 90; calculating the phase volume fractions of the multiphase flow using the two apparent VFs 100; determining the actual bulk mass flow rate of the multiphase flow 110; calculating the mass flow rate of one or more of the phases using the phase volume fractions and actual bulk mass flow rate 120. Apparatus for implementing the method includes a Coriolis meter, a differential pressure meter and a microwave meter.
