1、The measurement principle

　　Antenna system to launch and microwave receiving energy is very low, very short pulse. Lei Dabo waves travel with the speed of light. Through the electronic components to run time into level signals. Measurement of this special time extension method can realize stable, accurate in a very short period of time.Even if the condition is very complex, the presence of false echo, with the latest micro-processing technology and debugging software also can analyze the level echo accurately.

　　Microwave antenna to receive the reflected pulse and transmitted to the electronic circuit, a microprocessor to signal processing, to identify the micro pulse generated on the material surface echo. Echo recognition is completed by the pulse software, the accuracy can reach millimeter level. From the material surface distance between D and T pulse is proportional to the time travel:

　　D=C×T/2

　　Where C is the speed of light，Because of the air tank is a known distance E, L:

　　L=E-D

　　By setting the empty tank height E (= zero), the full height of F (= full scale) and some application parameters, application parameters automatically makes the instrument to measure the environment. 4 - 20mA with a corresponding output.

2、Application

　　6.3G radar level gauge is suitable for liquid, paste, granule and block material level and non-contact measurement, suitable for changes in temperature, pressure big; there is an inert gas and volatile.

　　The measurement method of microwave pulse, can work normally in the industrial frequency band range. The beam energy is low, can be installed on all kinds of metal, non-metallic container or pipe, no harm to human body and environment.
