• 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
• A low full scale value must be selected for abrasive media (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 sound velocity
(0.5 Mach).
• The maximum mass flow depends on the density of the gas: formula → 83
To calculate the flow limit, use the Applicator sizing tool → 81
Pressure loss To calculate the pressure loss, use the Applicator sizing tool → 81
System pressure → 20
