Radar level meter antenna by narrow microwave pulse, the pulse propagation in space at the speed of light, meet the measured medium surface, the part of the energy to be reflected back, by the same antenna. Emission pulses and the time interval of the received pulse and the antenna to the measured medium surface is proportional to the distance. Due to the electromagnetic wave propagation and very high speed, pulse and receiving pulse time interval is very small (nanosecond) it is difficult to confirm, 90X series of 26G radar level meter adopts a special demodulation technology, can accurately identify the transmitted pulse and pulse interval, thus further calculate the antenna to the measured medium surface distance.

D :Blind Area
Datum measurement: Screw thread bottom or the sealing surface of the flange
Note: Make sure the radar level meter the highest level cannot enter the measuring blind area (Figure D shown below).
Characteristics of water conservancy industry application:
- Radar level meter adopts a recommended industry emission frequency of 26GHz, so it has beam angle is small, concentrated energy, has stronger anti-interference ability and greatly improves the precision and reliability of measurement.
- Small antenna size, easy to install and dustproof cover antenna protection device.
- Light weight about 1KG, easy to install.
- The measurement range of up to 70 meters, covering a large reservoir water level measurement.
- With a variety of output circuit interface and data acquisition system.
- The pulse working mode, radar level meter transmit power is very low, no harm to human body and environment.
