M & WMR Series Water Meters

M and WMR Water Meters are the industry’s smallest water meters. They offer the best cost, performance and long life. The M utilizes the multi-jet principle assuring an equally distributed load on the impeller minimizing wear and maintaining accuracy. The WMR contains an in-line axial turbine which allows foreign matter to pass through the meter without clogging. Wide clearances in the measuring chamber and negligible area of contact between static and moving parts are the main reasons for the high reliability of this design even in hard water. Available in 3/4″, 1″, 1 1/2″ and 2″ sizes.
