4.6 COMMISSIONING

Upon initial installation, it is strongly recommended that

both the System-10 and its associated flow meter be

commissioned to ensure that they are properly installed

and functioning correctly. This process involves verifying

the mechanical installation, measuring flow and

temperature signals and then comparing these

measurements to the specified installation and operating

parameters listed on the certificate of calibration

provided with the meter. The data collected during this

initial commissioning process will then serve as baseline

data for periodic revalidation of the meter operation.

COMMISSIONING PROCEDURE - ONICON BTU METERS

Please read all installation instructions carefully before proceeding. Wiring diagrams are located in the
appendix of this manual. Use the Btu meter certificate of calibration to verify that the specified
installation & operating parameters match the actual conditions at the location where the meter is
installed. A worksheet for checking off these steps and recording measured values is located on the
following page.

Confirm flow meter

location and adequate

straight pipe run to

achieve desired results.

Confirm that the flow

meter location is iden-

tified and selected as

per section 4.5 of this

manual.

Is the flow meter located in the correct location as required by the plans?

Compare actual straight pipe upstream and downstream of the flow meter

location to the recommended distances identified in the flow meter installation

manual.

Note: The flow meter manual is very conservative, assuming worst-case pipe

obstructions. Contact ONICON to discuss specifics of your application. If

straight pipe run is very short, consult ONICON PRIOR to installing the flow

meter to discuss the possibility of upgrading to a different flow meter.

Review and record the flow meter location program setting.

Confirm pipe size &

material.

Confirm that the flow meter is tagged for the pipe diameter and material it is

installed in and that this information corresponds to the information listed

on the Btu meter certificate of calibration. When in doubt, measure the

circumference of the pipe.

Pipe O.D. = (circumference / 3.14) – (insulation thickness x 2)

Confirm insertion

depth and orientation

(for insertion meters

only).

Each insertion type flow meter comes with an attached insertion gage and

instruction tag. Ensure that meter is inserted to correct depth and that the

electronics enclosure is parallel with the pipe, with the arrow in the direction

of flow.

Confirm temperature

sensor thermowell

installations.

Confirm that the thermowells are properly installed and the bottom of the well

is in the flow stream. Make certain that only the components supplied with the

installation kit were used and that additional bushings were not added.

Confirm temperature

sensor installations.

Confirm that the temperature sensors are properly installed, and each sensor is

bottomed out in the well. A small amount of thermal compound should be

applied to the tip of each sensor to improve the thermal transfer.

Each sensor has a black sleeve on the cable coming up from the metal sensor.

This sleeve in cut to length for the thermowell. When the sensor is fully

bottomed out in the well, the retaining nut can be tightened without any of the

black sleeve protruding through the nut.

Confirm connection to

correct ONICON Btu

meter.

Confirm that the flow meter serial number matches the Btu meter serial

number (when ordered together). Also confirm that the serial numbers of the

temperature sensors match the Btu and flow meters.
