Through the antenna system to launch and receive very low energy very short microwave pulse. The radar wave runs at the speed of light. The operating time can be converted into a level signal by means of an electronic component. A special time extension method ensures stable and accurate measurements over a very short period of time.
Even if the situation is more complex circumstances, there are false echo, with the latest micro-processing technology and debugging software can also accurately analyze the level of echo.
The antenna receives the reflected microwave pulses and transmits them to the electronic circuit, which processes the signal to recognize the echo generated by the micro-pulses on the surface of the material. The correct echo signal recognition is done by the pulse software, the accuracy can reach millimeter level. The distance D from the surface of the material is proportional to the time travel T of the pulse:
D = C × T / 2
Where C is the speed of light
Since the distance E of the empty can is known, the level L is:
L = E-D
By setting the empty height E (= zero), full tank height F (= full scale) and some application parameters to set, the application parameters will automatically make the instrument adapt to the measurement environment. Corresponds to 4-20mA output.
Intelligent series of radar level meter for liquid, slurry, pellets and block material level of non-contact continuous measurement, suitable for temperature, pressure changes; there are inert gases and volatile present occasions.
Using microwave pulse measurement method, and in the industrial frequency band within the normal work. Beam energy is low, can be installed in a variety of metal, non-metallic containers or pipes, the human body and the environment are not hurt.
