<p>A method of measuring the flow rate of a continuous phase in a flowing multiphase fluid comprises measuring a velocity of the fluid by thermal anemometry at a location in the flow and simultaneously measuring the passage of a discontinuous phase at the same location using a local probe system, and using the measurement of the discontinuous phase to correct the measurement of the continuous phase so as to derive the flow rate thereof. Apparatus for performing the method comprises a thermal anemometer positioned at a location in the flow, a local probe system at the same location as the thermal anemometer and capable of measuring the passage of a discontinuous phase, and means for using the measurement from the local probe system to correct the measurement from the thermal anemometer so as to derive the flow rate of the continuous phase. <IMAGE></p> |
