Flow Indicator
The white, reflective Flow Indicator located on the top of the meter (refer to Figure 5) serves two
purposes: It verifies the impeller rotation to indicate that gas is flowing, and it is also used as an optical
photo-sensor (scanner) when a proving device is testing the meter for accuracy.
Each revolution of the Flow Indicator indicates 0.007407 cf (0.0002098 m
3
) of non-compensated gas flow
through the meter.
Note:
Keep the Flow Indicator covered by the rubber cap to help protect the viewing port
and keep it clean.
