INTRODUCTION continued
The KAM LRW™ Low Range Watercut / BS&W meter uses a patented microwave resonance technology, responding
to the differing electrical properties of water and oil to determine water content for ranges 0-3%, 0-5% and 0-10%.
The technology is highly repeatable and offers industry-leading accuracy (±0.03% for a 0-3% range). Additionally,
proprietary AnyDensity™ technology allows the instrument to compensate for any change in density across the
entire API gravity range. Compensation is based on a density input from a mass flow meter or densitometer and
all compensation is automatic. This is paramount in situations where a single truck or rail unloading site could see
swings in API gravity from the 20s to the 60s.
The unit can be calibrated and verified in line.
The LRW's high-quality components are made and assembled entirely in the USA, providing reliable and consistent
performance for long-term use.

INSTALLATION
KAM HIGHLY RECOMMENDS VERTICAL INSTALLATIONS WHEREVER POSSIBLE FOR OPTIMAL MIXING.
PLEASE NOTE: In all KAM LRW Installations, the user should ensure that the KAM LRW is installed in a turbulent
flow with the Reynolds Number above 2000. Additionally, all KAM LRW's should be installed in accordance with API
MPMS Chapter 8, Section 2, Table 1, and in accordance with KAM mixing recommendations.
INSTALLATION FLOW REQUIREMENTS
Remove all the protective packaging materials, and ensure that the LRW®sensor was not damaged
during transit.
It is always recommended that the LRW NOT be installed in direct sunlight, and in high-ambient-temperature
installations that it be installed with recommended sunshade.
In cold weather, if LRW is exposed to an open environment, KAM CONTROLS recommends operators insulate
the LRW, and if the pipeline is heated that the heating trace be extended to include the LRW.
If the pipeline is not going to flow for extended amount of time and the pipe is not heated then LRW should be
taken out to avoid damage to the sensor probe by freezing water.
Flow through (spool) units will be shipped partionally assembled. LRW unit can be wired prior to insertion into the
spool for convenience, but this is not required.
For 2" units:
Grease around the O-ring below the small
flange.
Insert LRW body into the spool and ensure
unit is fully seated. NOTE: LCD screen face
should be alined with direction of pipe flow.
Using a 5/8" Allen wrench, install (8) hex
screws around the circumference of the
flange until tight.
Screw pitot probe into valve until tight.
PRIOR TO INSTALLATION
LRW FLOW THROUGH ASSEMBLY
For 3" and 4" flow through units:
Screw LRW body into spool using 1 3/4"
wrench flat. KAM Controls recommends
using liquid pipe sealant rather than teflon
tape.
Screw pitot probe into valvue until tight.

Prior to mounting verify that the tip of the sensor
is all the way inside the seal housing.
FIGS. 3-3, 3-4.
If sensor is not fully enclosed inside the seal
housing, pull the shaft back until the probe is
all the way in the seal housing and tighten
the Socket Cap Screws on the locking collar.
This will prevent the LRW shaft from sliding
and the probe from getting damaged during
mounting.

INSTALLATION continued
INSERTABLE/RETRACTABLE INSTALLATION
The KAM®LRW sensor should be installed
according to FIG. 3-2. A full-opening ball valve is
used to isolate the LRW sensor from the pipeline
during installation or removal. The seal housing of
the LRW sensor allows the probe to be inserted
and removed from the pipe under pressure and flow
conditions. It is the user’s responsibility to
ensure that the LRW sensor be placed at the most
representative point within the flow profile (see
location recommendations above). The LRW
sensor should be inserted so that the window of
the probe is located in the center of the diameter of
the pipeline.
Note: If line pressure exceeds 100 psi, use a KAM®
IT Insertion Tool when installing/removing
the KAM®LRW sensor.

Measure the calculated MID from the top of the Locking Collar and place a mark with a permanent marker or
tape on the Shaft. FIG. 3-6.
Bolt or screw the LRW sensor to the valve or designated installation location.
(KAM CONTROLS recommends using thread sealant and not Teflon tape for the threaded LRW).
Open full opening valve.
Loosen Socket Cap Screws on the locking collar.
Push LRW sensor in until the mark is at the top edge of the locking collar. Ensure that LRW flow indicator is
aligned with pipeline flow direction. FIG. 3-7.

REMOVING THE LRW®SENSOR FROM FLOW THROUGH SPOOLS WITH FIXED INSERTION
To remove the LRW®sensor, first shut off power to the
instrument. Discontinue flow in loop from the main line and
drain fluid from loop. The probe can removed from the hous-
ing by removing the 5/8" hex screws on collar (2" models) or
unscrewed from spool body (3" and 4" models). FIG. 3-8. The
probe can then be lifted from the cell for testing/inspection/
calibration purposes.
Removal should be conducted in accordance with all regional
and Class requirements.
FIG. 3-8
INSTALLATION continued
REMOVING THE LRW SENSOR
To remove the LRW sensor, first shut off power to the instrument. Loosen the Socket Cap Screws on the Lock Down
Collar. Slide the LRW sensor upward until the probe rests inside the seal housing. There is a mechanical stop when
the unit is fully retracted. Retighten the Socket Cap Screws. Next, close the Full-opening Ball Valve tightly. Drain oil
from valve if possible. The LRW sensor may now be unbolted from the system.
Note: If line pressure exceeds 100 psi, use a KAM® IT Insertion Tool when installing/removing the KAM®LRW sensor.
Removal should be conducted in accordance with all regional and Class requirements.
Re-tighten the Socket Cap Screws.
Tighten the hex nuts holding down the Locking Collar one half turn. (FIG. 3-7) These should never be
over-tightened. Their major function is to apply light pressure on the chevron packing to ensure a seal between
the seal housing body and the insertion shaft.
