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. Dimensions

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).
