The guided wave radar series level meter is a new level meter based on the principle of time difference. The high-frequency pulse signal emitted by the electronic component propagates along the guide material. This feature makes this type of level meter suitable for many bad things that ordinary level meters cannot measure. Environment such as: low dielectric constant, dielectric with foam, etc.
Product description

Measuring principle>>

 

Guided wave radar is a measuring instrument based on the principle of time travel. The radar wave runs at the speed of light, and the running time can be converted into a level signal by electronic components. The probe sends out high-frequency pulses and propagates along the cable. When the pulses meet the surface of the material, they are reflected back and received by the receiver in the meter, and the distance signal is converted into a level signal.

  B: Blind area F: Maximum measuring range E: Full warehouse D: Empty height L: Material height

  ★Note: When using radar level timing, make sure that the highest material level cannot enter the blind area of measurement

 

Input>>

  

The reflected pulse signal is transmitted to the electronic circuit part of the instrument along the cable, and the microprocessor processes this signal to identify the echo generated by the microwave pulse on the surface of the material. The correct echo signal identification is done by intelligent software, and 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

  Because the distance E of the empty tank is known, the level L is: L=E-D

 

Output>>

 

Set by inputting the empty tank height E (=zero point), the full tank height F (=full scale) and some application parameters. The application parameters will automatically adapt the meter to the measurement environment. Corresponds to 4-20mA output.
