3.2 MECHANICAL INSTALLATION
ONICON Insertion Thermal Mass Flow Meters are designed to allow for insertion and removal,
when necessary, without interrupting flow in the pipe. To take advantage of this feature, the flow
meter must be installed through an isolation valve. The installation must allow for sufficient
overhead clearance to fully extract the meter, and a full 5/8” opening in the pipe wall is required
to clear the sensor head and allow for insertion. Make sure that your valves and fittings are full
port and at least ¾” in actual internal diameter.
CAUTION
ONICON insertion style flow meters must be installed through a valve assembly. Failure to do so
negates the ability to remove the meter without disrupting flow. It will also result in an excessive
amount of stem protruding from the pipe. Excessive stem lengths unnecessarily expose the meter
to incidental damage.

3.2.1 Installation Kits
ONICON offers installation hardware kits for commonly used pipe materials. The kits are
specifically designed for ONICON flow meters, and their use is strongly recommended.
The installation instructions contained in this manual assume that the pipe material is
welded steel. Contact ONICON for assistance, if necessary, if the installation involves a
different pipe material.
ONICON offers different types of kits based on the maximum operating pressure and
the maximum fluid temperature. This information is detailed in section 1.4 of this manual.
Contact ONICON for assistance before installing the kit if it does not meet the pressure or
temperature requirements of your application.
IMPORTANT NOTICE
This manual includes detailed installation instructions for welded steel pipe Contact ONICON if
installation hardware instructions are needed for other pipe materials.
