I.Measurement principle:
Transmit very low energy and very short microwave pulse then transmitting and receiving by the antenna system.Radar wave are running at the speed of light.Running time can be transformed into material level signal by electronic parts.A special type of time extension method can guarantee the stability and accurate measurement in a very short time. Even if the condition is complex , has false echo, can accurately analyze the level of the echo with the latest micro-processing technology and debugging software.
