Working principle
Micro pulses with high frequency are propagated and received through the antenna systems. The radar wave travels with the velocity of light. The flying time can be converted into signals of level through the electronic parts. A special method of extending or prolonging time can ensure the stable and exact measurement during the ultra short period.
Even under complicated working conditions, there are false echoes; the reflected echoes of the level can still be distinguished.
