Abstract

A fluid meter totalizing register assembly suitable for submerged service includes a fluid meter totalizing register and a register case. The register case has a housing comprising a water impermeable elastomeric material defining at least one wall of a cavity for receiving the fluid meter totalizing register. The register case includes a transparent lens of water impermeable material closing a top opening of the cavity in a water-tight seal with the wall of the housing, and a magnetic-force transmitting element of water impermeable material closing a bottom opening of the cavity in a water tight seal with the wall of the housing. The register includes a rotatable register element disposed within the cavity adjacent an inner surface of the magnetic-force transmitting element. The rotatable register element is driven by magnetic coupling with a rotatable meter element disposed adjacent an opposite, outer surface of the magnetic-force transmitting element.

Claims

1. A register case for a fluid meter totalizing register suitable for submerged service, comprising:

a housing comprising a water impermeable elastomeric material defining at least one wall of a cavity, said cavity having a top opening and a bottom opening and defining a volume therebetween for receiving and containing therewithin, in a region in between said top opening and said bottom opening, a fluid meter totalizing register,

a transparent lens closing said top opening in a direct, water-tight sealing engagement with said wall of said housing, and

a magnetic-force transmitting element of water impermeable material closing said bottom opening in a direct, water-tight sealing engagement with said wall of said housing,

the register having a rotatable register element disposed within said cavity adjacent an inner surface of said magnetic-force transmitting element, the rotatable register element adapted to be driven by magnetic coupling with a rotatable meter element disposed adjacent an opposite, outer surface of said magnetic-force transmitting element.

2. The register case of claim 1 wherein said elastomeric material is rubber.

3. The register case of claim 2 wherein said elastomeric material is an ethylene propylene rubber.

4. The register case of claim 1 wherein said housing is a solid, molded rubber material.

5. The register case of claim 1 wherein said housing and said magnetic-force transmitting element are integrally joined in manner to provide a water-tight seal.

6. The register case of claim 1 wherein said wall of said housing, within said cavity, defines a first groove sized and constructed for receiving a base flange of the register, said first groove adapted for engagement with the flange in a manner to secure and position the register within said cavity.

7. The register case of claim 1 wherein said lens defines a flange, and said wall of said housing, within said cavity, defines an annulus sized and constructed for receiving said flange of said lens in water-tight engagement.

8. The register case of claim 7 further comprising means for clamping said wall of said housing about said lens flange to form a water-tight seal.

9. The register case of claim 1 wherein said transparent lens is formed of a water impermeable material resistant to clouding due to prolonged exposure to groundwater and trace chemicals contained therein.

10. The register case of claim 9 wherein said water impermeable transparent lens material is glass.

11. The register case of claim 1 wherein said magnetic-force transmitting element is formed of a magnetically inert material.

12. The register case of claim 11 wherein said magnetically inert material is a copper alloy.

13. The register case of claim 1 wherein said wall of said housing comprises a portion defining a passageway for electrical wires from within said cavity.

14. The register case of claim 13 further comprising means for clamping said portion defining said passageway about the electrical wires to form a water-tight seal.

15. The register of claim 14 further comprising a sealant disposed about the wires in said passageway for sealing said housing about the electrical wires to form a water-tight seal.

16. The register of claim 15 wherein said sealant is caulking compound.

17. The register of claim 14 further comprising a packing material disposed about the wires in said passageway for sealing said housing about the electrical wires to form a water-tight seal.

18. A fluid meter totalizing register assembly suitable for submerged service, comprising:

a fluid meter totalizing register, and

a register case;

said register case comprising;

a housing comprising a water impermeable elastomeric material defining at least one wall of a cavity, said cavity having a top opening and a bottom opening and defining a volume for receiving and containing therewithin, in a region in between said top opening and said bottom opening, the fluid meter totalizing register,

a transparent lens closing said top opening in a direct, water-tight sealing engagement with said wall of said housing, and

a magnetic-force transmitting element of water impermeable material closing said bottom opening in a direct, water-tight sealing engagement with said wall of said housing; and

said fluid meter totalizing register comprising;

a rotatable register element disposed within said cavity adjacent an inner surface of said magnetic-force transmitting element, the rotatable register element adapted to be driven by magnetic coupling with a rotatable meter element disposed adjacent an opposite, outer surface of said magnetic-force transmitting element.

19. The register assembly of claim 18 wherein said register has a base flange, and said wall of said housing, within said cavity, defines a first groove sized and constructed for receiving said base flange of said register, said first groove adapted for engagement with said base flange in a manner to secure and position said register within said cavity.

20. The register assembly of claim 18 wherein said lens defines a lens flange, and said wall of said housing, within said cavity, defines an annulus sized and constructed for receiving said lens flange in water-tight engagement.

21. The register assembly of claim 20 further comprising means for clamping said wall of said housing about said lens flange to form a water-tight seal.

22. The register assembly of claim 18 wherein said transparent lens is formed of a water impermeable material resistant to clouding due to prolonged exposure to groundwater and trace chemicals contained therein.

23. The register assembly of claim 22 wherein said water impermeable transparent lens material is glass.

24. The register assembly of claim 18 wherein said magnetic-force transmitting element is formed of a magnetically inert material.

25. The register assembly of claim 24 wherein said magnetically inert material is a copper alloy.

26. The register assembly of claim 18 wherein said wall of said housing comprises a portion defining a passageway for electrical wires from within said cavity.

27. The register assembly of claim 26 further comprising means for clamping said portion defining said passageway about the electrical wires to form a water-tight seal.

28. The register of claim 26 further comprising a sealant disposed about the electrical wires in said passageway for sealing said housing about the electrical wires to form a water-tight seal.

29. The register of claim 28 wherein said sealant is caulking compound.

30. The register of claim 26 further comprising a packing material disposed about the electrical wires in said passageway for sealing said housing about the electrical wires to form a water-tight seal.

31. The register case of claim 18 wherein said elastomeric material is rubber.

32. The register case of claim 31 wherein said elastomeric material is an ethylene propylene rubber.
