Problems solved by technology

In some cases, existing filters attached to traditional water meters are small and prone to clogging with sand or similar particulate matter trapped in the water flow
In other cases, a flow restriction is induced which causes a head loss on the inlet side of the meter which can adversely affect the velocity of the water flowing out of the outlet side
In either case, the water meter will fail or be unable to provide the continuous high-volume, high-velocity flow of water required by the fire suppression system to combat residential building fires

Embodiment Construction

[0013] figure 1 and 2 show a preferred embodiment forming the high capacity fire water meter of the present invention. The water meter 1 comprises a hollow body 3 in fluid communication with axially aligned inlet and outlet ports 5 and 7 . As shown, the inlet 5 and outlet 7 have a set of threads through which the water meter 1 is integrated with the framework of the fire extinguishing system. However, the threaded opening could be replaced by a smooth hole (not shown) surrounded by the connecting flange. A standard magnetic drive recorder 9 is attached to the top of the main body 3 to provide a visual indication of the occupant's water usage (eg cubic feet or cubic meters). The recorder 9 is surrounded by a casing 10 (eg brass or plastic). A boot holding ring 12 is detachably connected to the main body 3 , thereby connecting the boot 10 and the recorder surrounded by the boot 10 to the water meter 1 .

[0014] That is, the recorder 9 is accommodated within a hood retaining...

Abstract

A large-capacity water meter, especially for use in fire suppression systems, by which the quantity of water used by residents is measured during normal times and during fire accidents when water flows at high velocity from a source to a sprinkler system in response to a residential fire. The water meter has a dual element filter assembly including an outer filter for trapping sand and other suspended particulates and an inner filter surrounded by, spaced apart from, and coaxially aligned with the outer filter. The adjustable flow control turbine assembly having a rotor responsive to water flow is housed in the inner filter. The turbine assembly and the dual element filter assembly are interconnected in the water meter to create uninterrupted water flow through radial and axial flow paths through the filter assembly to the turbine assembly.

Description

technical field [0001] Field of the Invention This invention relates to large capacity water meters and, in particular, to fire protection water meters for integration into fire suppression systems of the type commonly used to combat residential fires including sprinkler systems. A dual-element filter assembly designed to handle large volumes of water is attached to the turbine assembly to precisely measure water consumption and provide uninterrupted water flow in the event of a fire. Background technique [0002] Water meters have long been used to measure the volume of domestic and commercial water passing through water supply lines. In areas with rapidly increasing populations (e.g., Las Vegas), houses, condominiums, and condominiums are built very close to each other on narrow streets. Due to the high density of this new residential structure, it was difficult for fire trucks to quickly approach fires in distant structures due to obstruction from narrow driveways. In o...
