  • Rada-22 is a 25 GHz high-frequency pulse radar level meter with horn antenna. It is dedicated to solids level measurement. The maximum measuring range is 30m. Rada-22 is with a unique universal joint (adjustable guide) design to make the microwave emission direction adjustable during installation to fit the operation conditions on site. This effectively improves the measurement reliability for sloping solids. It is suitable for applications under heavy dust and high temperature environment.
  • The Rada-22 pulse radar level meter is designed with high frequency microstrip structure. A 25GHz microwave pulse signal is generated by the internal electronic circuit. Based on high frequency waveguide theory, the microwave pulses, through a PTFE emission pole, are transmitted from the end of an antenna. When the transmitted pulses hit the surface of the measured medium, part of the energy is reflected back and received by the same antenna. A special time expanding technique is used to produce a signal contains information of the time interval between transmitted pulse and received pulse. The distance between the antenna and the surface of the measured medium is then calculated as a result.
