I、 Principle：
Radar level meter antenna launch narrow microwave pulse, the pulse transmit with light speed in the space , some of its energy is launched back when met the surface of the measured medium and received by the same antenna. The time interval of the transmitted pulse and receive pulse is proportional to the distance of the measured medium surface. Due to the high speed of propagation of electromagnetic waves, time interval of the transmitted pulse and receive pulse is small (nanosecond level), is difficult to confirm. LRRD5X series of radar level meter, uses a special kind of correlation demodulation technology, can accurately identify the time interval of the transmitted pulse and receive pulse, thus further calculate the distance of the antenna to the surface of the measured medium.

II、Features： 
Radar level meter using the high frequency of 26G transmission frequency, thus has the following advantages:
1.Small beam angle,energy concentration, more flexibility for radar installation location. Have stronger anti-interference ability, greatly improve the measurement precision and stability
2.Small antenna size , easy to radar installation, at the same time has a better adaptability for small tanks and special tanks measurement
3.Measuring blind area is small, maximum increased the radar measurement range.
4.Shorter wavelength, better measure effect for powder, granular materials. 
5.Transmitted pulse signal, transmission power of radar level meter is extremely low, can be installed in all kinds of metal and nonmetal container, no harm to human body and environment. Du to adopted the advanced microprocessor and unique echo processing technology, radar level meter can be applied to all kinds of complicated conditions
