GDRD Pulse Radar Liquid Level Gauge

Current location:Home page -> Product -> Signal Conversion、Transmission、Other

Part One:Measuring Principle
Radar level meter emits a very narrow microwave pulse, the pulse to the speed of light in the space spread, hit the surface of the measured medium, part of its energy is launched back, received by the same antenna. The time interval between the transmitted pulse and the received pulse is proportional to the distance from the antenna to the surface of the measured medium. Since the propagation speed of the electromagnetic wave is extremely high, it is difficult to confirm that the time interval between the emission pulse and the reception pulse is small (nanoseconds). The GDRD5X series radar level meter uses a special correlation demodulation technique to accurately identify the time interval between the transmitted pulse and the received pulse, thus further calculating the distance from the antenna to the surface of the measured medium.

●Features
Due to the use of advanced microprocessors and unique EchoDiscovery echo processing technology. The radar level meter can be used in a variety of complex conditions. "False echo learning" function makes the instrument in a number of false echo conditions, can correctly confirm the true echo, to obtain accurate measurement results. A variety of process connections and antenna type, making the GDRD5X series radar level meter for a variety of complex conditions and applications. Such as: high temperature, high pressure and small dielectric constant dielectric measurement. Using pulse mode, the radar level meter transmission power is very low, can be installed in a variety of metal, non-metallic containers, the liquid level does not contact the reef accurate measurement, so that the level meter into a widely used advanced radar level meter. While the use of the product safety, no harm to the human body and the environment.
