Water flow meter Qn 2.5 cold water

This water meter is suitable for measuring flows / quantities of water in ordinary villas, perhaps mainly in tap water installations or smaller heating systems. The recommended flow for installation in heating systems is max. 2500 l / h. Unimag + can calculate flow rates below 8 l / h, thanks to friction-free materials used for bearings and contacts. Counter showing water consumption in the format 99999,999 m3.
