Abstract

A water meter housing assembly (10) comprises a cylindrical, plastic housing body (11), a non-cast housing bottom (13) of hydroformable or stamped brass, a single-piece strainer and sealing member (40) that is disposed in the housing bottom (13) and portions of non-cast hydroformable or stamped brass tubing (15) with spud ends (16, 17) for connection in a water supply line. The brass consists essentially of lead-free material. The assembly (10) is designed to provide a lower cost alternative to foundry cast meter housings. The assembly (10) also provides advantages in a method of vertical assembly that saves manufacturing cost.

Claims

1. A water meter housing assembly, comprising:

a cylindrical housing body formed at least in part of plastic;

a non-cast metal housing bottom in which the housing body is received;

wherein the housing bottom has an inlet and an outlet opening downward through said housing bottom; and

portions of non-cast metal tubing having an inlet port and an outlet port for connection to the inlet and outlet, respectively, of the housing bottom; and

wherein the metal tubing also has a supply inlet and a supply inlet for connection in a water supply line, the portions of tubing having a transverse partition located along the length thereof to separate an inlet flow from an outlet flow; and

wherein the metal in the metal housing bottom and the portions of tubing consists essentially of a lead-free material.

2. The water meter housing assembly of claim 1, wherein the tubing is made of hydroformed or stamped copper alloy.

3. The water meter housing assembly of claim 2, wherein the housing bottom is also made of hydroformed or stamped copper alloy.

4. The water meter housing assembly of claim 1, further comprising a single-piece sealing member that is disposed in a bottom of the housing bottom across the inlet and the outlet, said single-piece member forming a screen across the inlet for blocking debris in the inlet flow and said sealing member separating the inlet flow from the outlet flow near the inlet to the housing bottom.

5. The water meter housing assembly of claim 4, wherein the sealing member is made of synthetic rubber.

6. The water meter housing assembly of claim 4, in combination with a disc metering element, wherein the plastic body, the metering element, the housing bottom, the sealing member and the length of tubing can be vertically assembled.

7. The water meter housing assembly of claim 1, wherein the housing body is an integrally formed plastic body which together with the metal housing bottom forms a cavity for receiving a disc metering assembly;

and wherein a disc metering element without a thrust roller is disposed in said cavity.

8. The water meter housing assembly of claim 1, further comprising threaded fittings for assembly to opposite ends of the tubing to facilitate connection to a water supply line.

9. The water meter housing assembly of claim 1, wherein the housing bottom has a lip that runs around a lower edge of the housing body.

10. A method of assembling a water meter assembly having a plurality of components comprising;

a cylindrical housing body formed at least in part of plastic,

a non-cast metal housing bottom in which the housing body is received;

portions of non-cast tubing having an inlet and an outlet for connection to an inlet port and an outlet port, respectively, of the housing bottom; and

wherein the metal tubing also has a supply inlet and a supply outlet for connection in a water supply line, the portions of tubing having a transverse partition located along a length of the tubing to separate the inlet flow from the outlet flow; and

wherein the method comprises assembling the plurality of components along a substantially vertical axis corresponding to a central axis through the housing body.

11. The method of claim 10, wherein the plurality of components further comprise a disc metering assembly which is also assembled along a substantially vertical axis corresponding to a central axis through the plastic housing body and the disc metering assembly.

12. The method of claim 10, wherein the plurality of components further comprise a single-piece sealing member that is disposed in a bottom of the housing bottom over the inlet port and the outlet port.

13. The method of claim 10, wherein the metal in the metal housing bottom and the portions of tubing consists essentially of a lead-free material.
