  • Micropilot NMR84 is used for custody transfer and inventory control applications with NMi- and PTB-approvals. It meets the relevant requirements according to OIML R85 and API 3.1B. The NMR84 free space radar with drip-off planar antenna is specifically suited for stilling well applications. The superior drip-off antenna design with proven track record eliminates problems caused by condensation.

    • 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

    With planar antenna particularly suited for stilling well applications.
