The future: it's here and now!

The world's first 80 GHz radar for liquid measurement

As a technological leader in process instrumentation, we have been responsible for many standards in levels over the past 60 years. Our diversified portfolio offers measurement technology suitable for all applications.

With our latest innovation - the 80 GHz radar for measuring liquid levels in commercial transactions - even the highest requirements for complex tank gauge applications are met.

The beginning of the 80 GHz era for liquids - a new technology for greater reliability and security in your processes

The high-precision NMR81 Micropilot is the first radar in the world to measure levels in liquids with an emission frequency of 80 GHz with FMCW technology. This device has been developed for high-precision measurement of the level in commercial transaction applications and has been approved for this purpose by independent supervisory authorities. 80 GHz technology has a number of advantages:

• The focus is on the key aspects
  The NMR81 Micropilot uses an emission frequency of 80 GHz, which generates a narrow emission angle of 3 or 4 degrees, depending on the antenna used. In comparison, a 26 GHz radar with an antenna of the same size will have an emission angle of 10 degrees. Even in high, narrow tanks, the measurement is extremely reliable, as the radar beam avoids obstacles such as pipes or internal elements on tank walls.
• More efficient measurement in conical tanks and larger measurement ranges
  Focusing is easier to measure to the bottom of the tank using 80 GHz technology, as the beam does not come into contact with the converging inner walls. In general, larger measurement ranges than with other technologies are possible - while maintaining the same accuracy. Our tank gauge specialist, the Micropilot NMR81, achieves a maximum inaccuracy of 0.5 mm (1/32 inch) on measurement ranges up to 30 m (98 ft).

Main advantages:

• Simplified engineering thanks to a considerable reduction in basic conditions and limits to be met when using free-emission instrumentation
• Reduced assembly and maintenance costs thanks to the use of contactless instrumentation in demanding applications (abrasion, corrosion...)
• Increased installation availability and productivity with reliable measurement results
