INSTALLATION
EX11x/21x Installation
Fitting Installation. EX11x/21x adapters mate with a 1-1/2" female
NPT pipe thread adapter fitting.
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
compression 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 that follow). Be sure flow is in the direction of the arrow
on the housing. Fully tighten compression nut.
EX15x/25x Installation
'Hot tap' EX meters are designed so they can be installed and
serviced without depressurizing the pipe.
Fitting Installation. The EX15x/25x 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, due to the small diameter tube the meter
can be installed 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 that
follow). Be sure flow is in the direction of the arrow on the housing.
Fully tighten locking collar and compression nut.
