Abstract
A method and apparatus for determining the water content of crude oil in a pipeline is disclosed. The device consists of S-band tarnsmitting and receiving antennas, and X-band transmitting and receiving antennas. These are used to determine the complex dielectric constant of the fluid in a pipeline. Water salinity and an adjustment to the mixing formula are calculated using X-band and S-band sidewall links. The overall water content of the pipeline can then be determined by using as S-band main link that transmits a wave through a representative portion of the entire pipeline.
