Micropilot NMR81 can be used for custody transfer and inventory control measurements and is certified by NMi and PTB, complying with the relevant requirements of R85 and API 3.1B. NMR81 is particularly suitable for measurement in free space with a maximum range of 70 m. It uses an 80 GHz droplet antenna with a small 3° beam angle, which prevents any obstacles close to the tank wall from affecting the measurement.

Advantages
Hardware and software design in accordance with IEC 61508, maximum safety SIL3 (in homogeneous redundant systems)
Maximum measuring accuracy of ±0.5 mm (±0.02"), therefore maximum reliability
Design complies with international metrology regulations, e.g. OIML R85 and API MPMS standards
Local and national certifications, e.g. NMi or PTB certification for custody transfer applications
Simple connection to higher-level DCS systems via open protocols, easy installation and trouble-free operation
80 GHz technology with a highly focused beam angle, unaffected by tank walls and other structures

Application
The 80 GHz droplet antenna is suitable for measurement in free space with a maximum range of 70 m, with a small beam angle, suitable for short nozzle applications close to the tank wall.
