DHN1985 Posts: 8 Rating: (0)	Hi there, We have some questions about Flow sensor MAG 5100 W: In Catalog Flow sensor MAG 5100 W, says: + NBR Hard Rubber and Ebonite Hard Rubber liner for all water applications --> Do you have any certificate about NBR Hard Rubber safe in drinking water application? Please send us. + Housing and flanges (NBR lining) is Carbon steel, with corrosionresistant two-component epoxy coating (min. 150 μm) Corrosivity category C4, according to ISO 12944-2. We don't know which exact Carbon steel is? Carbon steel ASTM A 105 or what? + Electrode material: Hastelloy. What is exact type of Hastelloy? Hastelloy C-4 or C-22? Please help us. Glad to hear it from you soon. Thank you very much.

DHN1985 Posts: 8 Rating: (0)	Hi Danw, Thank you for your support!!! I can not find certificate for NBR Hard Rubber safe in drinking water in the link you recommend us. There is only EPDM rubber drinking water approval. How about the other questions about Housing and Flange material, electrode material? Please feedback to us soon.

The process flanges are A105 but you can have 304 and 316L SS flanges on the MAG3100 if desired.
