Lead Free Brass hot water meter


Lead Free Brass hot water meters/Submeters

The WM-NLCH Series meter is a multijet dry-type totalizing water meter. It is produced in an ISO9001 certified production facility and is constructed in conformance with AWWA C708 standards. The product is built to NSF/ANSI 61 Annex G standards (but not certified yet) and conforms with lead-free plumbing as defined by California, Vermont, Maryland and Louisiana state laws and the U.S. Safe Drinking Water Act that took effect January, 2014.

Water flows through the meter’s strainer and into the measuring chamber where it drives the impeller. The impeller drives the mechanical register dials via a magnetic coupling. The WM-NLCH Series water meter consists of three basic components: main case, measuring chamber, and head ring. The main cases of all sizes are constructed using C87850 low-lead brass alloy.
