Caution: Avoid high differential pressure across the meter. Abnormal differential
pressures can damage internal meter components.
7. Alternate cracking open the upstream and downstream valves for a few seconds and
then slowly-over a period of 10 seconds (¼ PSIG systems)-turn the valve to the ¼ open
position and then to the full open position.
8. After the meter is pressurized, apply a soap solution or other good leak detecting liquid to
the connections to check for leaks.
9. Test the meter to verify the meter is registering the gas flow.
1. Press the button to activate the LCD.
2. Observe the LCD display and look for usage to increase.
Note: If the LCD does not display any expected consumption, investigate the
installation. If necessary, change out the meter.
10. Perform a shadow or lock-in test following company or utility procedures.
11. After the Intelis Gas Meter installation testing is complete, purge all air from the gas line
including the piping section.
Warning: Never allow gas to discharge into a confined space or area where there
are ignition sources unless precautions are in place to eliminate potential
hazardous conditions.
It is possible to get air detection alarms during Intelis Gas Meter installation due to
installation setups, gas pressure, flow rates, pipe length, and general installation
practices. Air detection alarms during installation should be ignored.
A rapid flow rate change can cause a temporary flow measurement hard failure alarm.
For example, a flow measurement hard fail alarm could occur during installation, T
est
Mode (proving the meter), external leak test (water tank test), or other rapid flow rate
change situations. The alarm will display on the LCD and as long as it is temporary (and
not continuously in the flow measurement hard fail alarm state), is acceptable behavior. If
the flow measurement hard fail alarm remains active and does not clear, remove the
meter and return it to Itron for evaluation.
Removing or installing the pipe plug
This section provides the steps to remove or re-install the pipe plug.
Removing the pipe plug
• Using a 3/16" hand-driven Allen wrench, remove the pipe plug.
