Material Level Measurement Tool: Radar Level Meter Solves The Problem Of Repose Angle

The term "repose angle" is ubiquitous wherever material level measurement exists. When an incline puts an object placed on it in a critical state of sliding down the incline, the smallest angle it makes with the horizontal surface is the angle of repose. The material level surface in many factories is wavy, which causes the material to have an angle of repose, posing challenges to material level detection. The Radar level meter can solve the problem of Angle of repose measurement very well and accurately measure the material level. Let's explore how it's done.

Radar waves are special electromagnetic waves that are easy to reflect obstacles encountered and have penetrating power and can penetrate interference sources such as vapor and dust in the air. Radar level sensors use these characteristics of electromagnetic waves to detect material levels. When various solid materials are stored in warehouses or warehouses, since the materials have an angle of repose, the echo reflection will produce diffuse reflection, thus forming interference echoes and false echoes.

Through advanced echo processing and data processing technology, radar material level measurement can eliminate interference echoes and false echoes. At the same time, the high frequency, small opening angle and excellent penetration performance of the radar wave itself make it compared with other non-standard Contact testing standards offer better performance. Currently, most of the Radar level meters used are integrated products that use a two-wire power supply and output 4~20mA analog signals. They also support HART digital signals and various fieldbus digital communication protocols, making it easy to connect to computer monitoring systems. Debugging can be done locally or remotely.

Radar material level meters can solve the problem of material angle of repose measurement, but correct installation and debugging must be paid attention to during use to ensure the effect. The sensor should not be installed in the middle of the dome tank as this may result in signal loss. The installation position should be at 1/2 of the radius of the container, with a minimum distance of 30 cm from the tank wall to avoid the feed opening and false reflections. In addition, it is necessary to avoid false reflections caused by the equipment within the beam angle, especially away from the 1/3 cone radiation area closest to the antenna. Obstacles must be avoided to ensure that the antenna does not tilt toward the tank wall.

Through radar level meters, we can effectively solve the problem of material angle of repose measurement and achieve the accuracy of material level measurement. However, it should be noted that many measured media may produce a large amount of dust, which will adhere to the probe of the Radar level meter over time. This will affect the emission of radar waves, and in severe cases may even cause the radar waves to fail to be emitted normally. Therefore, we must clean and maintain the radar level gauge in time to avoid problems such as inaccurate measurement or even equipment damage.
