TX101/201 INSTALLATION
Fitting Installation. TX101/201 adapters mate with a 1-1/2” female
NPT pipe thread adapter tting. Any tting that provides the matching
NPT female thread may be used. Installation procedure compensates
for tting 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 tting (saddle, weldolet, etc.) on the
pipe.
Meter Installation. Loosen the compression nut so that the adapter
slides freely. Pull the meter fully upward and nger-tighten the compres-
sion nut. Using a thread sealant, install the adapter in the pipe tting.
Do not overtighten. Now loosen the compression nut, lower the meter to
the appropriate depth setting (see diagram and instructions that follow).
Caution: Do not allow the meter to fall into the pipe uncontrolled, as this
may damage the meter. Be sure ow is in the direction of the arrow on
the housing. Tighten compression nut fully.
TX115/215 INSTALLATION
‘Hot tap’ TX meters are designed to be installed and serviced without
depressurizing the pipe.
Fitting Installation. The TX115/215 adapters mate with a 2” FNPT
threaded tting for compatibility with the 2” isolation valve. Any tting
that provides matching NPT female thread may be used. The installation
procedure compensates for differences in tting 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 tting
(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 tting. 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 ow sensor. When the sensor is secure, open the valve and adjust
depth setting (see diagram and instructions that follow). Be sure ow is
in the direction of the arrow on the housing. Tighten locking collar and
compression nut fully.
