Plastic water meter with metal threads
First Claim
1. A water meter enclosure comprising:
- a non-metallic cover defining an interior cavity shaped to accept a metering device;
a metal ring including an outer surface, wherein threads are formed on the outer surface for connection of a water conduit to the ring; and
a non-metallic collar, the non-metallic collar including a non-metallic annular lip contacting a distal end of the metal ring to retain the metal ring proximate the non-metallic cover.

Abstract
Embodiments of the present invention generally relate to flow meters and more particularly to improved plastic water flow meters for commercial or residential use. In various embodiments, a plastic water meter is provided that may include metal threads for connecting the water meter to a water system. In particular, the plastic water meter may include at least one spud that is shaped to receive and engage a plastic spud insert, in which the plastic spud insert may include a metal ring with a threaded outer surface. The plastic spud insert may include an annular lip portion extending outwardly to discourage removal of the metal ring when the spud insert is engaged with the water meter. Furthermore, the plastic spud insert and the inner surface of the metal ring may have complementary circumferential profiles to discourage relative rotation between the metal ring and the spud insert.
