Rupture disk The sensor housing protects the inner electronics and mechanics and is filled with dry nitrogen. The
housing of this sensor does not fulfill any additional secondary containment function. However, 15 bar
(217.5 psi) can be specified as a reference value for the pressure loading capacity.
For increased safety, a version with rupture disk (triggering pressure 10 to 15 bar / 145 to 217.5 psi)
can be used, which is available for order as a separate option.

Select nominal diameter by optimizing between required flow range and permissible pressure loss. See
the "Measuring range" section for a list of maximum possible full scale values.
• 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 
