Radar measurement with 79 GHz technology

| By Chemical Engineering



The Micropilot NMR81 (photo) utilizes 79 GHz technology to generate a narrow beam angle of 3 or 4 deg. Measurements are substantially more reliable, even in narrow tanks, because the radar beam avoids obstacles, such as baffles on the tank walls. Furthermore, measurements right to the bottom in very tall tanks are easier because the beam does not hit the tank walls prematurely. The technology permits very long measuring ranges of up to 70 m. In custody transfer, the instrument measures up to 30 m with an accuracy of±0.5 mm, which surpasses the recommendations of the American Petroleum Institute (API) and the International Organization of Legal Metrology (OIML). Micropilot NMR81 easily fulfills all API and OIML requirements. — Endress+Hauser, Inc., Greenwood, Ind.
