INSTALLATION
LOCATION
For optimal batch detection, KAM CONTROLS recommends that you install the in-station OFD™ sensor at the
first accessible pipeline location inside the terminal fence-line — upstream of the interface cut valve(s). This al-
lows the operator ample time to open/close the cut valves prior to the arrival of the product interface.
KAM CONTROLS also strongly recommends that you utilize a preview (or out-station) OFD™ sensor. This lets the
operator decide how to optimize each batch cut prior to actually making the batch cut at the in-station and gives
the operator more confidence in their decisions as well as the time to identify and resolve any issues that may
arise during a critical interface.

PRIORTO INSTALLATION
Remove all the protective packaging materials including the red cap placed at the tip of the sensor probe. En-
sure that the OFD™ sensor was not damaged during transit.
CAUTION: Do not stand the OFD™ sensor on the probe end or allow the probe to hit the ground or any hard
surface under any circumstances. This will damage the lens, and the OFD™ sensor will not work properly.

DO NOT install the
fast loop OFD™
sensor in a straight
portion of pipe.
It needs to be
mounted off the
bend opposite the
pump.
DO NOT install the
OFD™
sensor with the
lens facing directly
into the flow. If
the product has
particulate
matter in the fluid,
like sand, this will
sandblast the lens
and could cause
premature failure.
DO NOT attempt to
screw the OFD™
sensor either in
or out by hand.
Always use a
1 1/4" or 1 3/8"
wrench on the

Remove all the protective packaging materials, and ensure that the OFD™ sensor was not damaged during transit.
PRIORTO INSTALLATION
MAIN LINE INSTALLATION
The KAM®OFD™ sensor should be installed
according to FIG. 3-2. KAM CONTROLS
recommends installing the OFD™ sensor at a 2 or
10 o’clock position to ensure the tip of the probe
remains in the fluid. A full opening ball valve is
used to isolate the OFD™ sensor from the pipeline
during installation or removal. The seal housing of
the OFD™ sensor allows the optical probe to be
inserted and removed from the pipe under pressure
and flow conditions. It is the user’s responsibility to
ensure that the OFD™ sensor is placed at the most
representative point within the flow profile. The
OFD™ sensor should be inserted so that the tip of
the probe is located 1/4" above the inner wall of the
pipeline. This ensures that the probe is not
damaged when pigging the pipeline.
NOTE: If line pressure exceeds 100 psi, use a KAM®
IT Insertion Tool when installing/removing
the KAM®OFD™ sensor.
Lay the OFD™ sensor on the ground or a table.
Loosen Socket Cap Screws on the locking
collar. This will allow the OFD™ shaft to slide
through the seal housing.
Push the OFD™ shaft though the seal housing
until the OFD™ probe sits flush with the end of
the seal housing or seal housing flange. FIG.
3-3 and 3-4. (Remove red protection cap on the
tip of the probe if it has not been removed.)
Place a mark with a sharpie or a permanent
marker on the shaft at the edge of the locking
collar. (Do not use anything sharp to mark the
shaft as this will create grooves that will
damage the O-rings in the seal housing.)
