Abstract

See full text

An apparatus for measuring a water content in a multiphase fluid flow stream is provided. The apparatus includes a measurement section configured to obtain a series of electrical measurements of the multiphase fluid flow stream over a first predetermined time interval, and determine a minimum electrical measurement Fmin_baseline from the series of electrical measurements. The measurement section also is configured to calculate a running average of the frequency (Fmin_gas_pattern) from the series of electrical measurements indicative of a change in a gas flow pattern of the multiphase fluid flow stream over a second predetermined time interval. The measurement section further is configured to calculate a corrected electrical measurement F_calc_WC for determining the water content in the multiphase fluid flow stream by subtracting the running average of the frequency. Fmin_gas_pattern from the minimum electrical measurement Fmin_baseline.
