Abstract
A method of, and apparatus for measuring the relative proportions of oil and water in a flowing multiphase fluid includes allowing the gas, oil and water phases of the multiphase fluid at least partially to separate, diverting at least some of the separated gas phase from the flowing fluid, into a bypass conduit, through a separating module, such as the tank of a homogenizing unit, where the gas phase tends to separate and collect above a pool of fluid, and measuring the relative proportions of oil and water in the undiverted fluid. A valve is located in the bypass conduit which has an inlet leading from the upper section of the tank (where gas collects) and an outlet joining the outlet pipe leading from the homogenizing unit downstream of metering apparatus.
