Solutions for tricky level measurement challenges

What is radar?

Radar is the abbreviation for "radio detection and ranging" which means "radio-based location and distance measurement". This technology is based on electromagnetic waves. A radar device emits a concentrated electromagnetic wave, which is reflected by objects as an echo and then evaluated by the device according to various criteria.

Depending on the application, the following information can be obtained from the reflected waves:
-the angle or the direction to the object
-the speed of an object (Doppler effect)
-the contours of an object
-the distance to the object

The latter point means that radar technology is also used for determining fill levels. This has become increasingly important in recent decades and has been continuously developed. The areas of application now extend from simple storage tank applications to complex process containers with a wide variety of challenges.
