Getting focused: Using 80-GHz radar sensors for liquid level measurement

摘要

Using 80-GHz transmission frequency liquid-level measurement can improve signal focusing to allow accurate, reliable measurement in tanks with agitators, heating coils, and other internal obstructions. That's because a narrower emitted beam makes radar a realistic option for use on ball valves, and increased transmission frequency correlates to a smaller antenna making it ideal for retrofitting and use on smaller tanks.
