Abstract (en)

[origin: WO2013081845A1] Techniques are provided for measuring one or more parameters in a multi-phase metering system. The multi-phase metering system includes a transport structure configured to transport one or more flow components of a flow process. Electrodes may be disposed concentrically with a cross-section of the transport structure to determine parameters of fluids flowing through the cross-sectional area. The multiphase metering system includes measurement electronics having measurement circuitry including a balance load having an impedance that is substantially equal to a parasitic impedance of the multi-phase metering system. The measurement electronics also includes a processor suitable for determining one or more parameters, such as flow velocity, flow volume, etc., based on a current sensed by the measurement circuitry.
