March 14, 2016 - Endress+Hauser releases Micropilot NMR81 radar level sensor for high-accuracy custody transfer applications. The sensor is certified by independent test authorities to an accuracy of up to ±0.5mm.

Micropilot NMR81 uses 79 GHz technology to generate a narrow beam angle of 3° or 4°. Measurements are substantially more reliable even in narrow tanks because the radar beam avoids obstacles such as baffles on the tank walls, and is thus unhindered by interfering signals.

Furthermore, measurements right to the bottom in very tall tanks are easier because the beam does not hit the tank walls prematurely. Installation relatively close to the tank wall is possible with the narrow beam angle. The technology permits very long measuring ranges of up to 70 meters. In custody transfer, the instrument measures up to 30 meters with an accuracy of ±0.5mm.

Custody transfer applications require the highest measurement performance. The American Petroleum Institute (API) and International Organization of Legal Metrology (OIML) recommend an accuracy of 1mm (1/16”) for the level instrument under factory calibration conditions, and within 4mm (3/16”) for the entire measurement system after installation on the tank. Micropilot NMR81 easily fulfills all API and OIML requirements. Additionally, the antenna is equipped with a gas-tight feed-through. This “second line of defense” is particularly important for handling highly toxic or diffusive products.
