APPARATUS AND METHOD FOR PROVIDING A FLUID CUT MEASUREMENT OF A MULTI-LIQUID MIXTURE COMPENSATED FOR ENTRAINED GAS

摘要

An apparatus for determining a fluid cut measurement of a multi-liquid mixture includes a first device configured to sense at least one parameter of the mixture to determine a fluid cut of a liquid in the mixture. A second device is configured to determine a concentration of gas in the mixture in response to a speed of sound in the mixture; and a signal processor is configured to adjust the fluid cut of the liquid using the concentration of the gas to determine a compensated fluid cut of the liquid. The parameter of the mixture sensed by the first device may include a density of the mixture (e.g., by way of a Coriolis meter), a permittivity of the mixture (e.g., by way of a resonant microwave oscillator), or an amount of microwave energy absorbed by the mixture (e.g., by way of a microwave abosorption watercut meter). The signal processor may employ different correction factors depending on the type of a fluid cut device used. The second device may include a gas volume fraction meter.
