SECTION 3.0: INSTALLATION

WARNING

This flow meter may be installed in pipes which are under high pressure or pipes filled with

combustible gases. Accidents with these systems can cause serious injury or death. Only persons

experienced with high pressure and/or combustible gas distribution systems and fluid metering

should attempt to install, adjust, or remove the flow meter. Please read all instructions carefully

before attempting to install or service a flow meter.

ONICON will be happy to assist with technical recommendations and to provide guidance by phone
or e-mail. On-site field engineering, installation and service are also available at an additional cost.

3.1 INSTALLATION SITE SELECTION

Install the flow meter where it will be accessible for personnel to perform necessary periodic
maintenance. The clearance required for installation is a minimum of 9” from the pipe wall
to the nearest obstruction above the electronics enclosure. Refer to Section 1.5 WORKING
ENVIRONMENT for additional considerations.

ONICON insertion style flow meters must also be correctly oriented in the pipe with respect to
the direction of flow.

The drawings below illustrate the relationship between flow direction and the orientation of the
meter when installed in the pipe. Contact ONICON for assistance if this relationship does not
allow for proper installation.

WARNING

GENERAL PRACTICES:

For best results, install the flow meter in a straight run of pipe, free of bends, tees,

valves, transitions and obstructions.

Straight run requirements vary based on the nature of the upstream obstruction.

See the table on page 10 for guidelines in determining upstream straight run

requirements. Depending upon specific location details, more or less straight run

may be required to produce a satisfactory flow profile.
