Continuous monitoring for % concentration of water in oil emulsions

The 4100-OWM is used for monitoring as the water phase changes to oil in a tank or pipe. A probe inserted into a tank or pipe measures the capacitance field. This is ideal for general monitoring of oils and other liquid phase changes in a process.

The 4100-OWM sensing probe monitors the capacitance field around the probe within a concentric shield, tank or pipe.

The emulsion characteristics of water to oil is not strictly linear and the Arjay controller allows for a 5 point calibration to enhance accuracy over an extended range. This instrument is ideal for general monitoring and trending of process conditions.
