The LRRD serials ultrashort microwave impulse with very short emission energy can be emitted and received through antenna. The radar wave moves at the velocity of light. The moving time can be converted into substance position signal through electrical components. A special time-extension method can secure stable and precise measurement within very short time.

Even under very complicated working conditions, such as the existence of false wave echo, it is possible to precisely analyze the wave echo of the substance position by using the latest micro-processing technology and deb ing software

LRRD Serials Smart radar level meter, for its characters of non-touchable measurement, can precious measure the media of pollution and corrosion. Its stable and accurate apparent is also shown in complex measurement. Outputs an analog signal 4~20mA, can be controlled by remote. It is adopted an unique micro-wave technology,Echo-tech process  applied for various industrial condition. The pulse working method can measure small dielectric constant media,and safely applied in metal and nonmetal vessels. It is not harmful for human body and environment.
