Endress+Hauser’s Micropilot NMR81 radar has a transmission frequency of 79GHz for level measurement in liquids.
The new instrument, which specialises in high-accuracy custody transfer applications, is certified by independent test authorities to an accuracy of ±0.5mm.
In addition, says the company, the microwave beam angle of three or four degrees ensures reliable measurements without any interfering signals – even in narrow tanks with baffles.
Endress+Hauser also says that 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.
