In recent years, the alumina industry has developed rapidly in China, and the level meter has set off a wave of high tides. For this industry, what kind of level meter is more appropriate?
Radar level meters have high measurement accuracy, low maintenance difficulty, and less restrictive conditions, but the radar level meter should pay attention to the consideration of the dielectric constant, a non-contact radar level meter is not suitable for low dielectric constant medium measurement.
The alumina industry uses many tanks in production, and the measurement medium is various slurries and alkalis. The slurry has a high dielectric constant, but the tank is mostly stirred and heated.
From the advantages and disadvantages of several commonly used level meters and the characteristics of the medium, the alumina industry is more suitable for radar level meters. However, its complex working conditions also place higher requirements on the installation of radar-level meters.
First of all, pay attention to the obstacles in the tank. Inside the alumina tank, there are heating coils, stirring vanes and fixed steel beams, all of which need to be considered, otherwise, interference echoes are likely to be generated.
Secondly, pay attention to the steam and foam inside the tank as well as the temperature. All these features can affect the measurement of the radar level meter, when selecting the type, pay attention; to later maintenance, and also pays attention to the antenna cleaning.
At present, the radar level meter is the most widely used among various level meters, with the highest measurement accuracy and the most convenient post-maintenance. With the progress of technology and lower prices, radar level meters will play a role in more and more fields.
