Seametrics IP100-200-SERIES - Manual (Page 4)

Immersion. The IP100/200 Series standard sensors are not
designed for continuous underwater operation. If this is a
possibility, as in a flooded vault, a unit modified for immersion
should be specified (Option -40).
Depth Setting. It is important for accuracy that the sensor
be inserted to the correct depth into the pipe.
1. Please visit www.seametrics.com and select the
K-factor Calculator located at the bottom of the
home page to find dimension 'D' (insertion depth
setting) above.*
2. Measuring from the outside of the pipe to the joint
in the housing, as shown in the diagram above,
adjust the sensor to Dimension D and hand-tighten
compression nut.
3. Align the conduit housing with the centerline of the
pipe, as shown. Be sure the arrow on the housing
points in the direction of flow.
4. Check Dimension D one more time.
5. Tighten the compression nut fully.
RECORD YOUR SETTINGS
Once you have the meter set up and operational, it is impor-
tant to record your meter setttings and save them for future
reference.

Piping. For best results, the IP sensor should be installed
with at least ten diameters of straight pipe upstream and five
downstream. Certain extreme situations such as partially-
opened valves are particularly difficult and may require fifteen
diameters upstream. (See Straight Pipe Recommendations.)
Horizontal is the preferred installation orientation, since it
improves low-flow performance slightly and avoids problems
with trapped air. Bottom, top, and vertical pipe installations
are all acceptable if required by the piping layout. (See Full
Pipe Recommendations.)
These flow sensors are not recommended
for installation downstream of the boiler
feedwater pump where installation fault
may expose the meter to boiler pressure
and temperature. Maximum recom-
mended temperature is 200˚ F.
