How To Choose The Right Level Measuring Instrument According To The Working Conditions Of Alumina

In the alumina industry, the demand for level measuring instruments is far more than what is seen on the surface. Level measuring instruments play an important role in many processes, from raw material slurry preparation to desiliconization. So, when choosing a level instrument, is the alumina radar level meter more suitable or the ultrasonic level meter? In order to choose the right measuring instrument, we need to have a clear understanding of the level measurement of alumina working conditions.

In the alumina process, the medium for the level measurement of alumina working conditions is mostly various slurries, most of which are based on water, so the dielectric constant of the medium is relatively high. From this point of view, the alumina radar level meter is very suitable. However, there are often obstacles such as steel beams, heating coils, and stirring blades in the tanks in the alumina process. And some ultrasonic level meters are not suitable for high temperature, high pressure or vacuum environments. Therefore, if there are heating coils in the tank, special attention should be paid to temperature changes. Under such working conditions, try to choose a radar level meter to avoid affecting the measurement.

If there are stirring blades in the tank, the slurry may vibrate, causing foam or vortexes. In addition, when there is a heating device in the tank, the slurry may generate steam, causing the antenna to scar. When choosing an alumina radar level meter, pay special attention to these two factors. When installing the level meter, pay attention to avoiding obstacles such as stirring blades.

In addition to the above two points, there is another important note: many tanks in the alumina process have multiple discharge ports. When installing the level meter, pay attention to choosing the right location.

In the alumina process, each process is closely connected. If a process has problems or stops operating, subsequent processes will also be affected. Therefore, the selection of the level meter is crucial, especially during maintenance, so that maintenance can be carried out without stopping.

Whether choosing an alumina radar level meter or an ultrasonic level meter for level measurement, the key is to understand the working conditions and determine which measurement method is most appropriate. When necessary, a combination of multiple measurement methods can be used to achieve accurate measurement.
