Description:

Guided wave radar level meter are a kind of measuring instrument based on the time travel , radar wave are travelling as light speed , the travel time can be transformed into level signal by the electronic parts . The detector can send the HF pulse and spread along cable , when the pulse meet the level surface , it will be reflected and received by the receptor inside the instruments , then the receptor will transform the distance signal into level signal.

Input

The reflected impulse signal is transmitted along the proble to the circuit of the gauge . The microwave processor processes this signal , and recognizes the wave echo of the microwave impulse from the material surface . The correct wave echo signal is recognized by the intelligent softwave , the distance from the material surface D is proportional to the flying time of the impulse T:

D=C×T/2

C is the velocity of light .

As the distance of the empty tank E is known , so

L=E-D

Output

By inputting empty tank height E(zero point) ,full tank height (full measuring range) and some application parameter are set .With the application parameters , the transmitter will automatically adapt itself to the measuring enviroment, corresponding 4-20mA output .

Measuring Distance

The following table indicates the relations between mediums and measuring distance

Applications:

Used for grain bin,oil/ fuel/water/powder tank, liquid
