PetroLine for Petrochemical Level Measurement with Special Materials
The PetroLine is the specialist for aggressive media with special material and testing requirements. When resistance to aggressive media requires special materials like 904L, 6Mo or similar, this product line offers pressure ratings from 20 bar to 150 bar in ASME B36.10 schedule dimensions.
Explore the specialized solutions of the PetroLine for your petrochemical applications.
PetroLine

Specialized for Demanding Industries
The complete design is oriented to ASME standards but also covers European PED requirements. When full X-ray capability of all welds is required, direct side connections are replaced by tees – enabling all applicable non-destructive testing methods.
In LowDensity design, liquids with densities from 0.32 g/cm³ can already be measured. The proven spherical float technology in titanium enables highest pressure resistance without internal pressure increase.
Magnetic switches and transmitters for continuous signal transmission extend functionality for demanding control system integration. These aggressive media level indicators are available in the complete range of 2- and 3-wire devices in normal or Ex variants (ATEX/IECEx). Highest quality standards ensured through test certificates up to EN10204-3.1 and factory acceptance tests.
