Watercut meter is an integral component of the multiphase meter. This meter works on low energy gamma photo absorption principle. It is available as single gamma meter or dual gamma meter based on measurement requirements and the presence of various phases. Single gamma meter measures two phases, for example oil and water in the absence of gas or liquid and gas. Dual gamma meter measures the watercut in the presence of gas or can be used to compensate for salinity in produced water in the absence of gas. It can measure hydrocarbon/water over the full range of 0-100%, regardless of which liquid is the continuous phase. Typical accuracy of measurement of water cut is +/- 1% abs. for the full range of watercut in the absence of gas.
