At The Time interval The Between the transmitted pulse and the received pulse is proportional to the distance from the antenna to the surface of the measured medium.Because the electromagnetic wave propagation speed is extremely high, the time interval between the transmitted pulse and the received pulse is very small (on the order of nanoseconds). It is difficult to confirm. The 90X series 26G radar level gauge uses a special demodulation technology To accurately identify the transmitted pulse and the time interval of the pulse is received to further calculate the distance of the antenna from the surface of the measured medium.
