Product Description
For use in submetering applications where compact size and pulse output are desired. The MTW MJ20/MJ420 multi-jet water meter uses a polymer casing design to allow for low weight and reduced cost but augments the meter with brass threads to reduce the likelihood of stripped threads during installation. The MJ20/MJ420 meet NSF/ANSI 61 and 372 standards. The MTW MJ20/MJ420 may be installed either horizontally or vertically.
