• Promass I: 40 bar or 600 psi
Limiting flow See Page 91 ff. (“Measuring range”)
Select nominal diameter by optimising between required flow range and permissible pressure loss.
See Page 91 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...50% of the maximum full scale value can be considered ideal.
• Select a lower full scale value for abrasive substances such as fluids with entrained solids (flow
velocity < 1 m/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 (see formula on Page 93)
