3.2.1 Installation Kit
ONICON oers a wide range of installation hardware kits for commonly used pipe materials. The kits are specically
designed for ONICON ow meters, and their use is recommended.
The use of ONICON installation hardware kits accomplishes two important objectives. First, it ensures that the proper
hardware is used. Second, it simplies order processing by standardizing the dimensions of the installation hardware.
ONICON must have an accurate measurement of the overall height of the installation hardware as measured from the
outside wall of the pipe to the top of the valve in order to determine the correct stem length when assembling the meter
in our factory. ONICON documents refer to this dimension as the stack height
3.2.2 ONICON Standard Installation Hardware Kit
Standard installation hardware kits are designed to be installed on piping systems that are drained and at atmospheric
pressure. The access hole is drilled (1” minimum) prior to installation of the branch outlet with 1” NPT threads, close nipple
and full port ball valve. Once the isolation valve is installed, the piping system can be ushed, lled and pressurized. The
ow meter may now be inserted or removed by hand without having to drain the system. Please read all instructions
before proceeding with meter insertion.
3.2.3 ONICON Hot Tap Installation Hardware Kit
ONICON oers an alternative installation hardware kit when it is not practical to relieve pressure and drain the system. In
this case, a 1¼” branch outlet, close nipple and 1¼” full port ball valve are installed rst. Then, a hot tap drilling apparatus
is used to drill a 1” diameter hole through the valve. This eliminates the need to shut down and drain the pipe. Please read
all instructions before proceeding with meter insertion.
ONICON installation hardware kits consist of three separate component parts:
Dierent pipe materials require dierent branch outlets and may include additional
bushings to properly size the opening.
