Can the WM2 water meter be used for residential water metering?
No. The WM2 does not meet the new federal regulations for drinking water. Applications it would be great for would be for irrigation (where water will not be ingested), industry, cooling towers. If you need NSF 372 / NSF 61, Annex G certified you should use our WM-NLC Meter. If you just need Lead Free meters that are not NSF certified you can use our WM series (Lead Free Brass) or WM-PC Series (Plastic).
