Note 1—Accuracy ensures that the calibration gas equivalent flow is ±1% of full scale when 22 ± 3ºC in
temperature is obtained for the primary reference in the specified operating pressure range. If the service gas
and calibration gas are the same, the measured gas is ensured to be ±1% of full scale in the specified operat-
ing pressure range as to our primary reference.
Note 2—The proof pressure specification does not ensure operation or accuracy.
Note 3—Use of Viton or Chloroprene rubber may be required depending on the intended flow rate range.
