Endress+Hauser

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.

 

Description

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.
