Flow Meter & Totalizer II for Fire Sprinkler System

Accurately measures outlet static and residual water pressures and flow from 2-1/2" hose connections. The "Totalizer II" facilitates the initial and periodic testing of pressure regulating valves in sprinkler and standpipe systems per NFPA 13, NFPA 14, and NFPA 25 requirements. This versatile device can also be used for standpipe, fire pump, and hydrant flow testing.
