Model WCM 7300ME Temperature Compensated Water Cut Monitor

The Model WCM 7300MEis designed to provide the highest possible sensitivity, resolution, and accuracy for water content determination in crude oil, other hydrocarbons, or other low dielectric liquids from a max of 25% to levels below 0.01% parts per million (ppm). In oil and natural gas (condensate) production, water cut measurements are significantly improved with the WCM 7300ME technology. Enhanced digital signal processing and full product temperature compensation are two of the technological advancements utilized by this device. Water cut, process temperature or probe electrical value can be selected for viewing without removing condulet cover by use of a supplied magnet to operate an internal reed switch.


• NACE adaptable.
– Can be modified for use in NACE applications.
