Instrument knowledge|Radar level meter, how to reduce the interference in the tank on the measurement When we install the radar level meter, we will encounter many on-site storage tanks with supports, such as beams and brackets,etc . . . These supports will interfere with the signal of the radar level meter. If the above interference objects appear in the radar emission area, when the normal liquid level is below the interference objects, it will inevitably affect the normal measurement of the radar level meter, and false echo signals will appear. When encountering such situatio...

Precautions for selection of radar level gauge

When selecting the type of radar level gauge, consider the influence of stirring and vacuuming, and pay attention to the power supply and output signal.1. Selection under stirringIn a tank with stirring, guided wave radar is generally not used. The force of stirring can easily bring the cable of the guided wave radar into the propeller, or bend the rod of the guided wave radar. Therefore, only high-frequency or low-frequency horn radar for non-contact measurement can be selected.If the lowest liquid level on site is above the stirring propeller, it generally has no effect on the measurement. I...

Intelligent radar water level meter helps carry out flood prevention work

Intelligent radar water level meter helps carry out flood prevention workRecently, as tropical disturbances in the southern coastal areas of my country have developed into tropical depressions, heavy rainfall has appeared in many areas of southern my country, and the flood control warning has been sounded. Since my country entered the flood season, a new round of flood control and early warning work has once again been put on the agenda. In flood warning work, the status of monitoring instruments can hardly be shaken. In order to do a good job in flood control and early warning, and prevent pr...

Why choose the radar level sensor in industrial process level instruments?

Why choose the radar level sensor in industrial process level instruments? The radar level sensor can measure the level that many other level instruments cannot measure, radar level sensor uses the microwave pulse measurement method and can work normally within the specified frequency range. It can be used in environments where inert gases and volatilization exist under the interference of temperature or pressure changes. The radar level sensor is a non-contact continuous measurement type process level instruments, which can be used to measure the level of li...

Factors that should be considered when designing signal processing of radar level meter

The radar level meter is a very practical level measurement tool. In the actual industrial application site, there will be many non-ideal situations. When designing the signal processing method for the radar level meter, the following five factors must be considered:1. The application occasions of radar level meters are often confined narrow spaces, rather than open huge spaces. The signal emitted by the radar level meter is an electromagnetic wave, which diverges in space and has all the characteristics of electromagnetic waves, such as reflection, diffraction, and re...
