Field of application

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.

80GHz drip-off lens antenna suited for free space applications up to 70m offers high beam focusing for applications with nozzle situated close to tank wall.

Process connections: Flanges
Temperature: -40 to +170°C (-40 to +338°F)
Pressure: Vacuum to +16bar (Vacuum to +232psi)
Maximum measuring range: 70m (230ft)
Accuracy: ±0.5mm (±0.02")
Transmitting frequency: 80GHz
International explosion protection and custody transfer certificates, overfill prevention WHG, SIL

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