in which the process pressure is greater than 2/3 of the secondary containment burst
pressure.

"Technical Information" document
Rupture disk
To increase the level of safety, a device version with a rupture disk with a trigger pressure
of 10 to 15 bar (145 to 217.5 psi)can be used (order code for "Sensor option", option
CA
"rupture disk").
Rupture disks cannot be combined with the separately available heating jacket .

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 → 252
• 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 → 252
