DCRD1000C Series Guided Wave contact cable type Smart Radar Level Meter for Liquids Or Solids
1.Working principle 

Guided Wave Radar is the measuring instruments that based on the time travel principle, the radar wave travel in speed of light, run time can be converted into a level signal by the electronic component. the probe emit the high-frequency pulse and spread along the cable probe, the pulse come across the material surface and reflect back then receive by the instrument receiver and converted the distance signal to level signal.

Input

Reflected pulse signal conduction transmit along the cable to the electronic circuit part of the instrument, the microprocessor processes this signal, identify the echo that generated by the microwave pulses on the material surface. Correct echo signal recognition accomplish by the intelligent software, the distance D that from the material surface is proportional to the pulse time travel T: D=CT/2 (C represent for speed of light)

as the empty tank distance E is already known, the level L is: L = E-D.

 

Output        

by entering the empty tank height E (= zero), full tank height F (= full scale) and some applications parameters to set up, application parameters will automatically adapt the measurement environment. Corresponds to 4-20mA output.
