A multiphase flowmeter and method of determining the proportions of two or more fluids flowing in a conduit and also the flow rate of each of the fluids present is disclosed. One or more sensors are mounted in the fluid flow to monitor a sensed area, with each sensor including electrical means in the form of a fluid identifier probe and temperature means in the form of a thermal fluid velocity heat loss sensor. A processor is used to calculate the proportions of fluids present in the sensed area from the sensed electrical property and the flow rate from the sensed temperature differential. Spot measurements are achieved by making the sensed area substantially smaller than a cross-sectional area of the conduit. An array of sensors may be used. |
