80 GHZ Radar Meter Level Measuring Tool Tank Liquid Water Transmisor De Nivel De Cement Silo Transmitter 80G Radar Level Sensor
Principle
The extremely narrow microwave pulse emitted by the antenna on radar level instrument can travel at the speed of light and part of its energy. which is reflected off the surface of target medium, is received by the very same antenna.
The time lapse between pulse emission and reception by the antenna is proportional to the distance between the surface of target medium and the reference point on antenna．However。due to the fact that the electromagnetic wave is Transmitted at extremely high speed. which leads to the tiny time lapse (nanosecond level) and makes it difficult to be identified.
QRL×series of radar level instrument have adopted a special demodulation technology. Enabling itself to detect the time lapse between pulse emission and reception correctly, and eventually generate accurate measurement result.
