Abstract: A method of determining a fraction of one or more phases in a multi-phase fluid in a conduit is provided. The method includes exciting (602) a sensing device to cause emission of electromagnetic waves of a range of frequencies into a multi-phase fluid. The sensing device comprises an antenna and a dielectric layer, selected to cause resonance in at least one of a first set of frequencies or a second set of frequencies based on a flow state of the multi-phase fluid, when placed proximate to the multi-phase fluid. The method also includes receiving (604) transmitted or reflected electromagnetic waves from the multi-phase fluid. The flow state of the multi-phase fluid is selected (606) based on a classification parameter. Fractions are determined (608) utilizing at least one fraction determination model that is selected based on the flow state of the multi-phase fluid.

Abstract: A method for determining a phase composition of a multiphase mixture flowing through a pipe is presented. The method includes exciting one or more patch antennas configured to operate over the range of frequencies. Further, the method includes acquiring at least one of a transmitted signal and a reflected signal over the range of frequencies from the one or more patch antennas. Moreover, the method includes estimating the phase composition of the multiphase mixture based on a group delay determined from at least one of the transmitted signal and the reflected signal. A system for determining a phase composition of a multiphase mixture flowing through a pipe is also presented.

Abstract: A system includes a plurality of movable members and an electromagnetic wave probe disposed within at least one movable member among the plurality of movable members. The actuation system is coupled to the plurality of movable members. The actuation system is configured to actuate and removably position the plurality of movable members to form a wave guide around at least a portion of an outer peripheral surface of the pipe assembly and position the electromagnetic wave probe proximate to the portion of the outer peripheral surface of the pipe assembly.

Abstract: A method of determining salinity of multi-phase fluids in a conduit includes exciting a sensing device to cause emission of electromagnetic waves of one or more frequencies into the multi-phase fluid. The method includes receiving transmitted or reflected electromagnetic waves from the multi-phase fluid. Furthermore, the method includes determining an intermediate parameter from the received electromagnetic waves. The method also includes obtaining estimated values of a plurality of parameters from the intermediate parameter. The estimated values comprise at least one of an estimated value of conductance, an estimated value of susceptance, an estimated value of differential conductance, an estimated value of differential susceptance, an estimated value of a real part of complex permittivity, and an estimated value of an imaginary part of complex permittivity. Salinity of the fluid is determined based, at least in part, on the estimated values of the plurality of parameters.
