1、 Measurement principle
Low energy microwave pulses are transmitted and received through an antenna system. The running time can be converted into level signals through electronic components. A special time extension method can ensure stable and accurate measurements in a very short period of time.
Even in complex working conditions where false echoes exist, the latest microprocessing technology and debugging software can accurately analyze the echoes of the material level.
