应用领域

Micropilot NMR81 is used for custody transfer and inventory control applications with NMi- and PTB-approvals and meets the requirements according to OIML R85 and API 3.1B. NMR81 is particularly suited for free space applications up to 70m. The drip-off lens antenna with 80 GHz transmitting frequency produces a sharply focused beam angle of 3° and avoids obstacles even close to tank wall.

好处

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

80GHz technology for narrow beam angle for sharper focus, without interference from tank wall and obstructions
