Radar level sensor for liquid measurement
Endress+Hauser’s Micropilot NMR81 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, 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 m. In custody transfer, the instrument measures up to 30 m with an accuracy of ±0.5mm. Micropilot NMR81 fulfills all API and OIML requirements and the antenna is equipped with a gas-tight feed-through.
