ABSTRACT:
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.
