Seametrics IP100-200-SERIES - Manual (Page 5)

IP110/210 INSTALLATION
Fitting Installation. IP110/210 brass/SS adapters mate with a 1-1/2”
female NPT pipe thread adapter fitting (2" for PVC). Any fitting that
provides the matching NPT female thread may be used. Installation
procedure compensates for fitting height differences. Cut a minimum
1-3/4” hole in the pipe. If possible, measure the wall thickness and
write it down for use in depth setting. Then install the threaded fitting
(saddle, weldolet, etc.) on the pipe.
Meter Installation. Loosen the compression nut so that the adapter
slides freely. Pull the meter fully upward and finger-tighten the compres-
sion nut. Using a thread sealant, install the adapter in the pipe fitting. Do
not overtighten. Now loosen the compression nut, lower the meter to the
appropriate depth setting (see diagram and instructions, preceding page).
Caution: Do not allow the meter to fall into the pipe uncontrolled, as
this may damag the meter
. Be sure flow is in the direction of the arrow
on the housing. Tighten compression nut fully.
IP150/250 INSTALLATION
‘Hot tap’ IP meters are designed to be installed and serviced without
depressurizing the pipe.
Fitting Installation. The IP150 and 250 adapters mate with a 2” FNPT
threaded fitting for compatibility with the 2” isolation valve. Any fitting
that provides matching NPT female thread may be used. The installation
procedure compensates for differences in fitting height.
If initial installation is performed on an unpressurized pipe, cut a
minimum 1-3/4” hole in the pipe. If possible, measure the wall thickness
and write it down for use in depth setting. Then install the threaded fitting
(saddle, weldolet, etc.) on the pipe.
If it is necessary to do the initial installation under pressure, any standard
hot tap drilling machine with 2” NPT adapter, such as a Transmate or a
Mueller, can be used. Ordinarily, it is not necessary to use an installation
tool, since the small-diameter tube can be controlled by hand at all but
the highest pressures.
Meter Installation. Remove the sensor unit from the valve assembly.
Using a thread sealant, install the valve assembly on the pipe fitting. If
the initial installation is a pressure (“hot”) tap, remove the 1-1/2” x 2”
adapter bushing at the back of the valve. Thread the tapping machine on,
open the valve, and tap using a minimum of 1-3/4” or maximum 1-7/8”
cutter. After retracting the machine and closing the valve, reinstall the
flow sensor. When the sensor is secure, open the valve and adjust depth
setting (see diagram and instructions, preceding page). Be sure flow is
in the direction of the arrow on the housing. Tighten locking collar and
compression nut fully.
