NOTE: The values in Tables 7 & 8 are based on ambient
conditions of 70oF (21oC) and 29.4 in Hg (74 mm Hg) and an
operating pressure range of 1.54 to 1.71 bar (22.3 psi to 24.8
psi). Any deviations from these conditions can affect flow
results.

NOTE: If the flow measurements are out of specification,
check the pressure in the unit. A combination of high or low
pressure and the tolerance of the particular flow meter can
result in inaccurate readings.
