MULTIPHASE FLOW METERING Subsea Multiphase Flow Meter The subsea Flowatch multiphase flow meter has been developed with the same tried and tested internal technology supplied in the Flowatch HS and run on the same software platform. It utilizes a patented high-speed gamma detector and a combination of DP measurement from a venturi, impedance measurement (capacitance/conductance of the oil/water mixture) and bulk velocity measurement via sensor cross-correlation. Built-in redundancies ensure the meter can meet a 25 year design life. The software and firmware are designed such that, as improvements in software are created they will be backwardly compatible with installed meters and downloadable from surface.
