Limiting flow
See the "Measuring range" section
Select nominal diameter by optimizing between required flow range and permissible pressure loss.
See the "Measuring range" section for a list of max. possible full scale values.
• The minimum recommended full scale value is approx. 1/20 of the max. full scale value.
• In most applications, 20 to 50% of the maximum full scale value can be considered ideal.
• Select a lower full scale value for abrasive substances such as liquids with entrained solids
(flow velocity < 1 m/s (3 ft/s)).
• For gas measurement the following rules apply:
– Flow velocity in the measuring tubes should not be more than half the sonic velocity
(0.5 Mach).
– The maximum mass flow depends on the density of the gas: formula
