Measurement of liquid level in polysilicon
Thread Content
Recently, there are many projects related to polysilicon, and level measurement is used in many of these projects. However, for the same production volume, different design institutes propose different numbers of solutions: for example, Institute 8 proposes more radar-based solutions, while Institute 6 proposes fewer of them; on the other hand, more magnetostrictive solutions are suggested. Do anyone know why? Additionally, there are several key points; the measurement points are quite complex. Are there any good solutions?
Actually, neither of these two types of level gauges is a problem; it’s just that the automation design engineers from the two design institutes have different habits and relationships, and personally I prefer radar level gauges.
Is there any substitution between magnetostriction and radar?
Basically, magnetostrictive materials are used because they are inexpensive, and since the medium is mostly water, the requirements aren’t that high
It’s just a matter of differences in the habits and approaches of the automation designers at the design institute; it is recommended to use radar level gauges. Generally, magnetostrictive technology is used for the metering of light oils in small-volume tanks.
We use radar level gauges; there are quite a few ROSEMOUT models, but in my opinion, E+H ones are better. I have never seen a magnetostrictive level gauge; I wonder if any netizen can post one for me to take a look at. This post was last edited by zhaohh3211 on 2008-7-25 08:02.]
It really depends on the practices of the design institute and the relationships there. The prices of radar E+H components have also skyrocketed. The ABM products from Canada are fairly good; the boss used to be the chief engineer at Miaoshengli
Most of the current polysilicon projects have been designed by Institute 8; there are also several such projects handled by Global. Institute 6 has already delivered one project of this kind. Many decisions are made based on the preferences of the design institutes, including those related to level measurement and other related issues.

Radar level gauges are used in situations where the containers are relatively large; they are easy to install and provide accurate measurements, but they are expensive. Whether such an investment is necessary is a decision to be made by the decision-makers themselves. Magnetostrictive level gauges have a simple principle of operation, a straightforward structure, and are inexpensive; they can measure most types of liquid levels. Personally, I prefer magnetostrictive level gauges.
