Applications
The Micropilot NMR81 is designed for commercial custody transfer and inventory control with NMi and PTB certifications, complying with OIML R85 and API 3.1B requirements. The NMR81 model excels in free-space measurements up to 70m. Its 80 GHz droplet-lens antenna produces a narrow beam with a 3° opening angle, minimizing interference even near tank walls.
The 80GHz droplet-lens antenna enables precise free-space measurements up to 70m, maintaining beam focus when installed near tank wall nozzles.
