A method of determining mass flow rate and phase distribution of gas/liquid two-phase flows is disclosed. The method uses a Coriolis-based mass flow meter. Flow streams of known mass flow rate and phase distribution are directed through the meter and correlation factors are obtained using an apparen ...

Kt Liu, Tanh V Nguyen: Gas/liquid flow measurement using coriolis-based flow meters. Chevron Research Co, LU LIYING, August 30, 1989: CN88107262

It discloses a method for determining steam quality and mass flow rate, which adopts Coriolis type instrument. When the flow with known quality and flow rate flows over the instrument, the frequency type output and corner type output of the instrument can be adopted to work out a plurality of releva ...
