The material load curves (pressure–temperature diagrams) for the process connections are included
in the separate "Technical information" documentation for the respective measuring device, which
you can download in PDF format at www.endress.com.
A list of the available "Technical information" documents can be found in the "Supplementary
documentation" section → Page 117
Pressure ranges of secondary containment:
• Promass F: DN 8 to 50: 40 bar or 600 psi; DN 80: 25 bar or 375 psi;
DN 100 to 150: 16 bar or 250 psi; DN 250: 10 bar or 150 bar
• Promass M: 100 bar or 1500 psi
• Promass E: No secondary containment
• Promass A: 25 bar or 375 psi
• Promass H: DN 8 to 15: 25 bar or 375 psi; DN 25 to 50: 16 bar or 250 psi
• Promass I: 40 bar or 600 psi
See information on Page 96 ff., ("Measuring range")
Select nominal diameter by optimising between required flow range and permissible pressure loss.
See Page 96 ff. for a list of max. possible full scale values.
• The minimum recommended full scale value is approx.
• 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).
• 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 98)
