Abstract
The salt content of a fluid in a pipeline or container in petroleum producing or refining operations is determined by obtaining a measure of water cut of an oil-water-free gas fluid mixture. The conductivity of the fluid is measured by radio frequency (RF) induction techniques, while the density of the fluid is measured and related to the liquid phase fraction of the fluid using gamma radiation techniques. The conductivity and liquid phase fraction are then used to determine salt content of the liquid phase.
