Proving
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 com-
pany 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. Attempt-
ing to program or configure parameters while the meter is in Test Mode will result in a tem-
porary 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.
