CM-3
Cut Monitor
with 409-1000 series electronics
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%. In addition, the monitor has been
employed on automatic well testers operating
up to 80% water. The addition of digital processing
and memory allows for linear ranges of 0 to
30%, 0 to 50%, or 0 to 80% water in oil.
The indicating transmitter is factory-calibrated
for each application and easily adjusted for
seasonal product and temperature changes using
Drexelbrook’s PC interface and HART®
protocol. The transmitter’s design minimizes
paraffin build-up, simplifying and reducing
the need for sensing element cleaning.
The monitor’s sensing element is designed
for easy installation through a tee in a vertical
section of the vessel’s outlet piping,
which permits simple cleaning, inspection,
and removal without having to drain the line.
The monitor’s 316SS sensor has no insulation
to blister, peel, or abrade, and its measurement
is unaffected by changes in ambient temperature.
The CM-3’s is unique in its ability
to avoid false “low-water” readings
when overloaded by conductive fluids, setting
it apart from similar instruments.
