Endress+Hauser presents the world’s first radar with a transmission frequency of 79GHz for level measurement in liquids. The new Micropilot NMR81 for high-accuracy custody transfer applications is certified by independent test authorities to an accuracy of ±0.5mm. The sharply focused microwave beam angle ensures safe and reliable measurements without any interfering signals even in narrow tanks with baffles.

Being the technology leader in process instrumentation, Endress+Hauser regularly sets standards in level measurement instrumentation. The new 79GHz radar is the newest innovation, providing a solution for even the most sophisticated level measurement applications in liquids. Micropilot NMR81 utilizes 79GHz 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, taking measurements right at the bottom of very tall tanks is 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 30m 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 a level instrument under factory calibration conditions, and within 4mm (3/16”) for the entire measurement system after installation in 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 defence’ is particularly important for handling highly toxic or diffusive products.
