The CM-3 Cut Monitor is a "Smart" Cut Monitor. It monitors the efficiency of oil/water separation vessels by measuring the percentage of water in oil. With its precise indication of water percentages from 0 to 50%, the CM-3 Cut Monitor can be used to indicate the effectiveness of wash tanks, freewater knockouts, heater treaters, and other separation vessels.

That information can be used on a "LACT" unit to divert "Wet" oil for additional processing/separation with ranges as low as 0 to 1%.

The CM-3 is unique in its ability to avoid false "Low-Water" readings when overloaded by conductive fluids, setting it apart from similar instruments.
