Abstract: A fluid meter (10) has a casing (11) providing a measuring chamber (27) and an inlet (18) and outlet (19) communicating with the measuring chamber (27). A partition (20) in the chamber (27) separating said inlet (18) from said outlet (19). A disc (28, 48) is positioned in the chamber (27) and includes projections (36) or niches (57) which are disposed in an arc relative to a center of the disc (28, 48) and the casing is provided with integrally formed depressions (37) or with projections (56) disposed opposite the projections (36) or niches (57) on the disc (28) to be engaged the disc (28) as the disc (28, 48) is nutated with the result of counteracting forces imposed on said disc (28, 48) by fluid flow.

Abstract: A compound meter assembly (10) has a housing (15, 17, 19), a high volume flow meter (14) disposed in a main flow passageway (22) for detecting a flow rate of relatively higher volume flows and a low volume flow meter (12) disposed in the secondary flow passageway (29) for detecting a flow rate of relatively lower volume flows. A flow distributor (70) is disposed in the inlet and disposed adjacent the entrance (27) into the secondary flow passageway from the main passageway, said flow distributor (70) having a central opening (71) for receiving the main flow and having flow ports (72) disposed around its circumference for allowing portions of the main flow to flow towards interior walls (26) of the housing (15, 17, 19) such that the flow is better distributed across a cross section of the main passageway (22) to maintain the accuracy of the meter at a crossover region (61, 62) between low flows being metered by the low volume flow meter (12) and high flows being metered by the high volume flow meter (14).

Abstract: A coated substrate for plumbing applications in which the leaching of metals into water contacting the substrate is significantly reduced, comprises an alloy having copper has a majority constituent and also comprising tin, zinc and lead; and a coating having a thickness in a range from 0.4 to 1.2 mils upon the substrate, the coating further comprising a mixture of an cationic epoxy resin material and a curing agent for said cationic epoxy resin material. The coating is preferably applied by electrodeposition and then cured by baking in an oven at approximately 400° F. for about twenty minutes.
