Free space radar transmitter, the standard sensor for highest demands in liquid level measurement, is utilized for continuous, non-contact level measurement of liquids, pastes and slurries. This radar technology has two different versions: pulse generated, which works on a ToF principal, similar to an ultrasonic device and Frequency Modulated Continuous Wave (FMCW), a consistent wave, which never loses touch with the material, making it better for agitated vessels. Free space radar is relatively unaffected by environmental conditions, for example, different gases or vapors, temperature and/or changing media. It's largely impervious to variations in process temperature or pressure,
and it can work in a full vacuum, making it the most universal non-contact level technology.
Endress + Hauser has 21 different variations of their Micropilot radar measurement product, suitable for various industries with features including, but not limited to - maintenance-free measurement, optimum price-performance ratio,
slim rod antennas for small process connections, and highly accurate, non-contact measurement.
