Working principle
The electronic units generate microwave pulses which are emitted and received by the antenna systems. The radar wave travels at the velocity of light, the flying time will be converted into level signals via the electronic components. A special time extending method can make sure the stable and accurate measurement within extreme short time.

Even under some complicated working conditions with false echoes, the level signals can also be recognized and collected with the latest microprocessor technology and the debugging software.
