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
