Difference Between Pulse Radar Level Gauge And Guided Radar Level Gauge

Both pulse radar level gauge and guided wave radar level gauge are radar level gauges, and many manufacturers can’t tell the difference when selecting models. The following briefly introduces the differences between pulse radar level gauges and guided wave radar level gauges. , From the difference, we can roughly determine the selection for us.
The guided wave radar level gauge measures the material level by processing the time when the radar wave is emitted from the probe to the surface of the medium and then returns to the probe. The principle of pulse radar is basically the same as that of ultrasonic radar. The radar emits a short microwave pulse, which is reflected at the liquid surface, and the radar receives the reflected echo through signal processing to obtain the target distance.
The pulse radar level gauge does not need to consider too many factors. It is more common to be used on tanks of 30 and 40 meters, and it can even be measured to 60 meters. There is no clear limit to the measurement medium;
The guided wave radar level gauge also needs to consider the force of the guide rod (cable), which is also due to the force. Generally, the measurement distance of the guided wave radar will not exceed 30m. However, guided wave radar has obvious advantages in some special working conditions, such as stirring in the tank and large fluctuations in the medium. In such working conditions, the measured value of the guided wave radar fixed at the bottom is more stable than that of the flexible radar; there are also small tanks. For level measurement, due to the small installation and measurement space (or a lot of interfering objects in the tank), ordinary radars are generally not applicable. At this time, the advantages of guided wave radars come out. For specific selection, please contact the manufacturer directly!
