COMMISSIONING WORKSHEET FOR ONICON BTU METERS
Please read all installation instructions carefully prior to proceeding with these steps. Wiring diagrams
are located in the appendix. Use the following worksheet for checking off the commissioning steps and
recording measured values:
STEP TEST/MEASUREMENT S/N: S/N: S/N: S/N:
1. Meter location
1a. Supply/Return/Unknown
2. Pipe size
3. Insertion depth and
orientation
4. Thermowell installation
5. Temperature installation
6. Match BTU meter, ow meter
and temperature sensor serial
numbers.
7. Supply voltage veried (Note
voltage.)
In order to proceed with the following steps, the BTU meter must be operating and connected to the network.
There must also be ow in pipes. Flow signal readings should be taken while holding the ow rate constant if
possible. Otherwise, take the various output readings as quickly as possible.
8. Note and record the SUPPLY
temperature.
9. Note and record the RETURN
temperature.
10. Note and record the FLOW
RATE.
11. Note and record the ENERGY
RATE.
12. Frequency output(s):
Avg = green, Top = white
Bottom = orange

13. Compare and record the
displayed values with those
shown on BTU meter
certicate of calibration
and the network, where
appropriate.
