It need not always be stainless steel!data, all that remains is the selection of the gauge bar, whose variety is available for all types.
Modern plastics are no “inferior plastic”, but rather an innovative alternative to stainless steels!
For use for the level indication of acids, often materials are required that show a high nickel proportion in the steel area. The raw materials are expensive and not always easy to acquire. Processing these materials is complex, time-intensive and thus expensive. Plastics offer a far more affordable alternative for the low pressure and low temperature range. With PVC, polypropylene (PP) and PVDF, many measurement tasks can be performed safely and efficiently.
Of course, a large number of float types for different parameters are available here as well in PVC, PP and PVDF.
WEKA can process more than stainless steel!
A proven example is battery acid, for whose resistance a highly alloyed nickel steel would need to be used or – much simpler and more cost-efficient – a PP magnetic visual level indicator. Not for no reason are all car battery housings made of plastic.
These level indicators are not allowed to be used in explosive areas (ATEX / IECEx), as the plastics tend towards static charging and thus could produce an energy sufficient for ignition.
Whether flanges or threads, the basic type including connections can be determined with simple pressure/temperature diagrams (p/T diagrams). Since there is the suitable float for all types, which WEKA chooses according to the process data, all that remains is the selection of the gauge bar, whose variety is available for all types.
