ABSTRACT:
A method for measuring the mass flow rate of liquid flow exiting a two phase (gas/liquid) feed nozzle. The method includes determining the Power Spectral Density from the output of an accelerometer in close proximity to the restriction orifice controlling the gas flow, or determining the Power Spectral Density from the output of a pressure transducer in contact with the gas flow on the down stream side of the restriction orifice. The liquid flow can then be obtained from a predetermined correlation between the RMS Vibrational Signal and the mass or liquid flow rate.
