Pressure ranges of secondary containment

• DN 250 (10"): 10 bar (145 psi)
Warning!
In case a danger of measuring tube failure exists due to process characteristics, e.g. with corrosive process
fluids, we recommend the use of sensors whose secondary containment is equipped with special pressure
monitoring connections (ordering option). With the help of these connections, fluid collected in the secondary
containment in the event of tube failure can be bled off. This is especially important in high pressure gas
applications. These connections can also be used for gas circulation and/or detection (Dimensions → ä 51).

Select nominal diameter by optimising between required flow range and permissible pressure loss. An overview
of max. possible full scale values can be found in the "Measuring range" Section.
• The minimum recommended full scale value is approx. 1/20 of the max. 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 fluids with entrained solids
(flow velocity <1 m/s (<3 ft/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: formula → ä 5
