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.
