Caution!
The flowrates shown are representative of the calibrated conditions only and do not necessarily
reflect what the meter can measure under operating conditions and actual internal pipe dimensions
found on site. To correctly size and select a meter, it is recommended that you either contact your
local Hauser representative or refer to Applicator (the Hauser sizing and selection
software).
