30 m (98 ft)
Field of application
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.
With planar antenna particularly suited for stilling well applications.
