INSTALLATION

Positioning the Meter

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 (3 o'clock or 9 o'clock position) is the preferred
installation orientation, since it improves low-flow
performance and avoids problems with trapped air and
sediment. (See Orienting the Meter diagram below.)
Bottom (6 o'clock), top (12 o'clock), and vertical pipe
installations are all acceptable if required by the piping
layout.

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).
Caution: These flow sensors are
not recommended for installation
downstream of a boiler feedwater
pump where installation fault may
expose the flow sensor to boiler pressure
and temperature. Maximum recommended
temperature is 200°F.
