A fluid impervious housing having an upper cavity for a water meter and a lower cavity for pressure regulating apparatus. A removable partition separates the cavities and removal of the partition provides access to both cavities for maintenance. The pressure regulator includes a reciprocable valve and the partition has a guide for such valve so that when the partition is removed the valve is accessible. The lower cavity is arranged to accommodate a valve structure employing Bellofram seals. A back pass check valve for affording reverse flow should the output pressure exceed the input pressure. A pressure relief valve for releasing water to the exterior of the apparatus should pressure downstream of the apparatus reach an excessive level. A screen for preventing entry of solid particulates into the relatively delicate meter mechanism in the upper chamber.
Combined water meter and pressure regulator apparatus comprising a fluid impervious housing having upper and lower cavities, a removable partition disposed in said housing and defining a boundary between said cavities, said housing having an opening communicating with said upper cavity, said opening being in alignment with said partition and sized to permit removal of said partition so as to afford access to said lower cavity through said opening, said opening being adapted to receive a water meter measuring chamber therein, said lower cavity having an inlet, an outlet and means for regulating the pressure in said outlet, input and output fittings on said housing, and means within said housing for communicating water from said input fitting to said output fitting through said upper and lower cavities in sequence so that flow from said output fitting is metered and is at a predetermined pressure.
Combined water meter and pressure regulator apparatus comprising:
Combined water meter and pressure regulator apparatus comprising a fluid impervious housing having two interior cavities, inlet and outlet fittings opening through said housing for respectively admitting water thereinto and discharging water therefrom, a removable partition disposed in said housing between said cavities, a water meter measuring chamber received in one of said cavities, means within said housing for communicating water through said cavities in sequence from said inlet fitting to said outlet fitting, means within the other of said cavities for regulating the pressure of water flow therethrough.
