  3. Theory – Non-Contact Radar Technology Radar Pulse FMCW • measuring the time t between the transmitted and the received pulse • Distance d is determined with: 2d Propagation speed of EM-waves is equal to the velocity of light

  4. 26 24 Theory – Non-Contact Radar Technology FMCW non-contact Radar Principle FMCW = Frequency Modulated Continuous Wave. FMCW-radar uses a high frequency signal (~ 24GHz) which transmit frequency increasing linearly 2 GHz within approx. 7 ms during the measurement (frequency sweep). The signal is emitted, reflected on the product surface and received time-delayed. For further signal processing the difference Df is calculated from the actual transmit frequency and the receive frequency. The difference is directly proportional to the distance. The frequency difference is transformed via a Fourier trans- formation (FFT) into a frequency spectrum and then the distance is calculated from the spectrum. The level results from the difference between tank height and distance. Theory of Operation

  8. Theory – Non-Contact Radar Technology Non-Contact Radar Level Meters • KROHNE Non-Contact Radar fully automated calibration rigs (up to 18 m / 59 ft) • Accuracy 0.5 mm / 0.02”

  9. Theory – Non-Contact Radar Technology Why do I use a Non-Contact Radar Level Meter? • FMCW = Frequency Modulated Continuous Wave • Used to measure level, distance, volume, reflection of • liquids (with / without solids contents) • pulps • pastes • slurries • Applicable in practically all industrial sectors • Only requirement:process product should have minimum dielectric constant and wetted parts must be corrosion resistant

  10. Theory – Non-Contact Radar Technology Why do I use a Non-Contact Radar Level Meter? • Non-Contact Radar meters are intrinsically accurate • Non-Contact Radar meters can’t contaminate • Non-Contact Radar meters are maintenance free • Non-Contact Radar meters measure a wide range of products • Non-Contact Radar meters measure process reflections
