The present invention is a method for determining the mass flow rate of liquid from each of the nozzles on a manifold of nozzles. A method is demonstrated to provide an absolute calibration technique.

Method to determine liquid flow rate for manifold feed nozzles

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.

Non-intrusive flow meter for the liquid based on solid, liquid or gas

A on-line method for detecting erosion or plugging for manifolded feed nozzle systems which carry two-phase liquid/gas flow by determining a liquid flow parameter related to liquid flow. The method can determine whether the erosion is at the liquid nozzle or the gas restriction orifice. The amount of erosion or plugging can be quantified.
