Stevens - Model HSI -Two Non-Contact Water Level Radar Sensor

Two non-contact water level radar sensors for outdoor use using impulse 24 GHz or 80 GHz plus and continuous wave radar technology. Conventional pulse radar emits periodic high-frequency pulse and continuous wave radar emits a continuous wave signal. The continuous wave radar can be a single-frequency continuous wave or a frequency-modulated continuous wave. 24 GHz radar sensors are typically used for applications where the measured surface is highly reflective, such as liquids and powders. 80GHz radar sensors are typically used for applications where the material being measured is less reflective, such as granular or bulk materials. 80GHz radar sensors have a smaller wavelength and can detect a higher resolution level and can also penetrate through dust, steam, or foam.
