Limiting medium pressure
range (nominal pressure)
The material load curves (pressure-temperature diagrams) for the process connections
are to be found in the following documents:
• Technical Information Promass 80/83 F, M (TI 053D/06/en)
• Technical Information Promass 80/83 E (TI 061D/06/en)
• Technical Information Promass 80/83 A (TI 054D/06/en)
• Technical Information Promass 80/83 H, I (TI 052D/06/en)
Pressure ranges of secondary containment:
• Promass F: DN 8...50: 40 bar or 600 psi; DN 80: 25 bar or 375 psi;
DN 100...150: 16 bar or 250 psi
• Promass M: 100 bar or 1500 psi
• Promass E: No secondary containment
• Promass A: 25 bar or 375 psi
• Promass H: DN 8...15: 25 bar or 375 psi; DN 25...50: 16 bar or 250 psi
• Promass I: 40 bar or 600 psi
Limiting flow See Page 81 ff. (“Measuring range”)
Select nominal diameter by optimising between required flow range and permissible
pressure loss. See Page 81 ff. for a list of maximum possible full scale values.
• The minimum recommended full scale value is approx.
1
/
20
of the maximum 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 82)
