Benefits

• Hardware and software developed according to IEC 61508 up to SIL3 (in homogeneous redundancy) for high level of safety

• Maximum reliability through accuracy up to ±0.5mm (±0.02″)

• Developed according to international metrology recommendations such as OIML R85 and API MPMS

• Local and country-specific certifications like NMi or PTB for custody transfer applications

• Simplified installation and trouble-free operations due to easy connection to major DCS systems via open protocols

• Unique drip-off antenna design eliminates measurement error due to condensation build-up
