Radar measurement Micropilot NMR81

Field of Application :

The Micropilot NMR81 is designed for custody transfer and inventory control applications, meeting the highest industry standards with NMi- and PTB-approvals. It complies with OIML R85 and API 3.1B regulations, ensuring accuracy and reliability in critical measurement environments. With an 80 GHz drip-off lens antenna, the NMR81 provides a sharply focused 3° beam angle, allowing precise level measurement even when installed close to tank walls. This makes it ideal for free-space applications up to 70m (230ft).
