guided wave radar is commonly used in liquid level measurement, the condition has certain requirements. And the operation condition of the radar using more, but the scope is limited. More commonly used for exposure level measurement. And have asked about working conditions, need no shade, dust, steam and so on all have larger interference.

guided wave radar thermometer has a big advantage in special operating conditions, such as mixing tank, medium to large fluctuations, such conditions with fixed at the bottom of the guided wave radar measured values than alternative stable; There are small tank level measurement, due to the installation of measuring the space is little, Or tank of distractors more) And ordinary thermometer is not applicable to the radar, guided wave radar thermometer are evident advantages; Have a low dielectric constant of working condition, regardless of the radar thermometer thermometer or guided wave radar measurement principle is based on dielectric permittivity difference, due to the launch of ordinary radar wave is divergent, when the dielectric constant of the medium is too low, the signal is too weak to measure is not stable, and is guided wave radar wave propagation along the wave guide rod signal is relatively stable, in addition the general guided wave radar at the bottom of the thermometer and detection function, can according to the bottom of the echo signal could be revised measurements, the signal is more stable and accurate.

radar thermometer is the use of ultra high frequency electromagnetic wave to the surface of the container being detected by the antenna to launch, when the electromagnetic waves bounce back after touching the liquid level, instrument to detect the spread to the echo of the time difference, and the liquid surface height is calculated. Conductivity measured medium, the better or the dielectric constant, the greater the reflection effect of echo signal, the better, antenna is radar thermometer key components, the shape of the antenna to radar wave focusing and sensitivity.
