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 ser-
vice gas and calibration gas are the same, the measured gas is ensured to be ±1% of full scale in the
specified operating pressure range as to our primary reference.
Note 2—The proof pressure specification does not ensure operation or accuracy.
