• The minimum recommended full scale value is approx. 1/20 of the maximum 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:
– The flow velocity in the measuring tubes should not exceed half the sonic velocity
(0.5 Mach).
– The maximum mass flow depends on the density of the gas: formula (  77)
Pressure loss
To calculate the pressure loss, use the Applicator sizing tool (  93)
