System-10 BTU Meter Manual 03/15 - 0651-16 / 18323 Page 28

4.6 COMMISSIONING

Upon initial installation, it is strongly recommended that

both the System-10 and its associated ow meter be

commissioned to ensure that they are properly installed

and functioning correctly. This process involves verifying

the mechanical installation, measuring ow and

temperature signals and then comparing these

measurements to the specied installation and operating

parameters listed on the certicate 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 certicate of calibration to verify that the specied

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.

1. Conrm ow meter

location and adequate

straight pipe run to

achieve desired results.

Conrm that the ow

meter location is iden-

tied and selected as

per section 4.5 of this

manual.

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

Compare actual straight pipe upstream and downstream of the ow meter

location to the recommended distances identied in the ow meter installation

manual.

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

obstructions. Contact ONICON to discuss specics of your application. If

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

meter to discuss the possibility of upgrading to a different ow meter.

Review and record the ow meter location program setting.

2. Conrm pipe size &

material.

Conrm that the ow 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 certicate of calibration. When in doubt, measure the

circumference of the pipe.

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

3. Conrm insertion

depth and orientation

(for insertion meters

only).

Each insertion type ow 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 ow.

4. Conrm temperature

sensor thermowell

installations.

Conrm that the thermowells are properly installed and the bottom of the well

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

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

5. Conrm temperature

sensor installations.

Conrm 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.

6. Conrm connection to

correct ONICON Btu

meter.

Conrm that the ow meter serial number matches the Btu meter serial

number (when ordered together). Also conrm that the serial numbers of the

temperature sensors match the Btu and ow meters.
