Abstract
A multiphase meter system including: transmitting and receiving antennas in the flow pipe, wherein the receiving antennas are at different distances from the transmitting antenna, and a control system configured to: apply an electromagnetic field to the transmitting antenna and receive signals from the receiving antenna induced in the fluid or the pipe by the transmission of the electromagnetic field; calculate a resonance quality of the signals received by at least one of the first and second receiver antennas; calculate composition or salinity of the fluid based on the resonance quality if the resonance quality is greater than a threshold value, and calculate composition or salinity of the fluid based on a transmission time difference of the signals received from the first receiver antenna and the signals received by the second receiver antenna if the resonance quality is below the threshold value.
