1.4 ADDITIONAL REQUIRED HARDWARE
All ONICON insertion type meters can be installed and removed via
a 1” or larger full port ball valve without system shutdown. The terms
“Standard” and “Hot Tap” refer to the installation method of the
isolation valve kit only.
Standard Installation Hardware: For new construction or scheduled
shutdown; once kit is installed, the ow meter can be installed or
removed without system shutdown.
Hot Tap Installation Hardware: For applications which require the
access hole in the pipe to be drilled through the valve using a wet
tap drilling machine while the hydronic system is pressurized and
operating.
NOTE: Installation hardware materials vary greatly based on pipe
material, pipe size and standard vs. hot tap versions.
