Patent ID: 8754657

Claim:
A salinity determining system for determining a salinity of water in a hydrocarbon emulsion of oil and water, the salinity determining system comprising: an antenna element configured to be in contact with the hydrocarbon emulsion; a switch coupled to the antenna element; a first analyzer device configured to be coupled to the antenna element via the switch, wherein the first analyzer device is associated with a first coincidence function based on first measured electrical parameters of transmitted radio-frequency (RF) energy in the hydrocarbon emulsion; and a second analyzer device configured to be coupled to the antenna element via the switch, wherein the second analyzer device is associated with a second coincidence function based on second measured electrical parameters of transmitted radio-frequency (RF) energy in the hydrocarbon emulsion, wherein the salinity determining system is configured to determine an intersection point of the first and second coincidence functions and to use the intersection point to determine a salinity of water in the hydrocarbon emulsion.
