Seals
For mounting sets with screwed-on connections:
• Viton: –15 to +200 °C (–5 to +392 °F)
• EPDM: –40 to +160 °C (–40 to +320 °F)
• Silicone: –60 to +200 °C (–76 to +392 °F)
• Kalrez: –20 to +275 °C (–4 to +527 °F)
Density 0 to 5 000 kg/m 3 (0 to 312 lb/cf)
Pressure-temperature
ratings
For an overview of the pressure-temperature ratings for the process connections, see
the Technical Information
Sensor housing
The sensor housing is filled with dry nitrogen gas and protects the electronics and
mechanics inside.
Rupture disk To guarantee the safety of the measuring device, the device version with a rupture disk
with a triggering pressure of 10 to 15 bar (145 to 217.5 psi) is the standard version used.

Flow limit Select the nominal diameter by optimizing between the required flow range and
permissible pressure loss.
For an overview of the full scale values for the measuring range, see the "Measuring
range" section →  178
• 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
