Chapter 5 Proving the Intelis Gas Meter
This section provides information about proving the Intelis Gas Meter. Meteorological
proving allows users to test the Intelis Gas Meter accuracy. Temper meters unpackaged in
the proving area for 24 hours prior to the testing.
Warning: Follow your company's standard operating procedures regarding the use
of personal protection equipment (PPE). Adhere to guidelines issued by your
company in addition to those contained in this document when proving meters.
The Intelis Gas Meter Test Mode and a prover station are used to confirm the accuracy of
the meter.
Note: The Intelis Gas ultrasonic meter is highly accurate and sensitive to air flow. The meter
displays registration to 0.001 CCF. The meter sensitivity makes it possible to see the index
incrementing even with the hub caps in place.
The prover station captures and counts pulses. Each pulse reflects a specific volume (pulse
weight) of gas. Pulse width is a length of time for the pulse. Both pulse width and pulse
weight are configurable parameters using FDM. The Intelis Gas Meter pulse weight must
match the prover setup as described in this section's proving instructions.
Note: The Intelis Gas Meter cannot be programmed (configured) or calibrated while the
meter is in Test Mode. You must exit Test Mode to program or configure the meter.
Attempting to program or configure parameters while the meter is in Test Mode will result in
a temporary error. If the valve icon is blinking, the meter is unable to go into Test Mode. Wait
a few minutes and try again.
Test Mode is used in a meter shop or by a regulatory body. Some meter configuration and
prover setup are required for the prover to properly interpret the meter pulses. Meter
configuration is completed using FDM. Proving the Intelis Gas Meter requires attaching the
pulse output prover cable between the meter and the proving station. After the test is
complete, the proving cable is removed and the meter returns to normal operation.
Important: 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,
Test 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.
