high performance guided wave radar water level meter

  RL82 guided wave radar level meter   Measuring principle
Guided wave radar is based on the principle of time travel is measuring instrument, radar wave running at the speed of light, running time can be transformed into material level signal by electronic parts.Probe a high-frequency pulse and probe spread along the cable type, when the pulse in the material surface reflected by the receiver inside the instrument, and the distance signal is transformed into material level signal.
The input
Reflection of the pulse signal along the cable to the instrument electronic circuit part, microprocessor to signal processing, identify the microwave pulse in the material surface produced by the echo.Correct echo signal recognition by intelligent software to complete, distance material on the surface of the distance D is proportional to the pulse of time travel T: D = C * T / 2 where C is the speed of light because of the distance of the empty cans E known, the level of L: L = E - D.
The output
By entering empty cans height E (= zero), full tank height F (= full scale) and some applications to set parameters, application parameters will be automatically adapt instrument to measure the environment.Corresponding to the 4-20 ma output.     Annie Sales Manager Beijing Zhongzhiguochuang Automation Equipment Co.,ltd    Tel:+86-10-52900365 Fax:+86-10-82561707 Mobile:+86-18600678435     Skype:huoshouyan678
