how to select Magnetic flow meter liner?
|Ceramic Liner Magmeters|
Most electromagnetic flow meter perform similarly. They usually vary in the features more than anywhere else. On one hand, those features can help keep your process reliable. On the other, the cost of the meter increases, and in some cases the investment won't pan out for you.
Take a moment to think about it. The magnetic flow meter liners always come in contact with the products. And some products react to those liner substances. Therefore you need to choose your liner carefully, unless you have a fairly inert product like water.
For example, if you have a corrosive product, you need a liner material that has a chemical compatibility with the product. Teflon makes for a good choice, as it gives you a wide range of product applications. If you see options like polytetrafluoroethylene(PTFE) and perfluoroalkoxy alkane (PFA), then you should know that they mainly differ in temperature limits.
On the other hand, for abrasive products, you have a variety of rubber and ceramic options you can consider. But that depends on your budget.
So there you have it. Nearly every brand you check out will have most of these options available for their magmeters. Just remember your product’s chemical compatibility!
