SECTION 3.0: INSTALLATION, REMOVAL & ADJUSTMENT
***CAUTION***
Insertion Flow Meters may often be installed in pipes which are under high
pressure. Accidents with these systems can cause serious injury or death. Only
persons experienced with high pressure systems and related knowledge in the
heating, cooling and fluid metering fields should attempt to install adjust or remove
the flow meter. Refer to the installation drawings before performing any work on
these meters.
ONICON will be happy to assist with technical recommendations and to provide
guidance by telephone and/or mail. On-site field engineering, installation and service
is also available at additional cost.
3.1 SITE SELECTION
Install the flow meter where it will be accessible for personnel to perform necessary periodic
maintenance. The clearance required for installation is typically 30-36” from the pipe wall to
the nearest obstruction above the valve assembly. This clearance dimension will increase
with large diameter pipes. The environment should be free of corrosive liquids/fumes,
temperature extremes and heavy vibration. The following diagrams should be used as a guide
to the proper location for installing the meter.
If yours is a single turbine meter and there is no suitable location, contact ONICON’s Sales
Office to discuss upgrading to a dual turbine meter. This meter is more tolerant of the
conditions that cause swirl, turbulence and flow profile distortions. Please make this decision
before installing the single turbine meter so that we may be able to give you credit if you elect
to upgrade to a dual turbine meter. Returns may be subject to a restocking charge.
