Selection of dual-rope guided wave radar
Thread Content
I would like to ask under what circumstances dual-rod or dual-cable guided wave radars should be used, and when coaxial guided wave radars are appropriate. What are the advantages of using a dual-rope guided wave radar?
Coaxial antennas have strong interference resistance, and the distance between the antenna and the tank wall requires to be relatively small.
When should one choose a double rod? The manufacturer says that dual rods are used for solid materials; some claim that dual rods can increase sensitivity. I want to know when it is appropriate to use dual rods
We make the selection based on the dielectric constant of the medium; generally, coaxial cables are used for those with a high dielectric constant, while dual-cable systems are used for those with a low dielectric constant.
Waves with low dielectric constant result in weak reflections that are difficult to detect. By using twin cables, the detection of reflected waves is improved, thereby enhancing the accuracy of measurements.
Our factory uses a single cable for gasoline and a double cable for diesel
I would like to ask: which one has a lower dielectric constant, the dual-bar or the coaxial type?
Generally, dual-rod or dual-cable configurations are considered only for media with low dielectric constants. These configurations serve to amplify the signal, thereby increasing the amplitude of the effective echo signal and enabling stable measurements.
Propane has a low dielectric constant; can it be measured using a dual-cable radar?
““Dual-rod or dual-cable guided wave radar”… Heheh, Mad Lei knows how to use two antennas after all. :lol
