Your water savings - Save Lives
Threaded retaining nut makes it easier to service in a valve box- The molded mounting tee provides consistent measurements and overall improved performance
- Four bladed lightweight impeller is sensitive enough to measure lower flow rates
- Smart electronics capable of better signal filtering
- Affordable enough to install on nearly all new and old systems
