Principle
The antenna of radar level instrument transmits a very narrow microwave pulse which propagates at the speed of light in space. When meeting the dielectric surface to be measured, part of its energy is reflected and received by the same antenna. The time interval of transmitting and receiving pulses is proportional to the distance between antenna and dielectric surface to be measured, and therefore the distance between antenna and dielectric surface to be measured can be calculated.
Features
With advanced microprocessor and unique EchoDiscovery echo processing technology, the radar level instrument can be applied to various complex working conditions.
The “Virtual Echo Learning” function enables the instrument to correctly identify true echo in the working conditions where there are multiple virtual echoes to obtain correct measurements.
Multiple process connections and antenna shapes allows GDRD5X radar level instrument series to be used in various complex working conditions and applications, eg. measurement of high temperature, high pressure and low dielectric constant.
In the pulse mode, the radar level instrument has very low transmitting power, can be installed in various metal and nonmetal containers, and has no damage to human body and the environment.
