ABSTRACT:
An improved meter bar assembly including an elongated casting (10) having threaded inlet and outlet ports (18) and (30) along with spaced, threaded swivel receiving ports (22), (36). Shoulders (54) are located in each of the swivel receiving ports (22), (36) and an auxiliary port (70) is also located in the casting. A cylindrical tube (72) is disposed in the auxiliary port and extends into the casting (10) to provide a mechanical barrier between the outlet port (30) and the swivel port (36). A cap (76) is provided for the tube (72) and a check valve (78) disposed within the tube (72). A pair of swivel tubes, (28) and (40) are threaded into the ports (22), (36) and one of the swivel tubes (40) includes an internal check valve (96). Both swivel tubes are provided with stop surfaces (50) that abut the shoulders (54) of the associated swivel tube receiving ports to positively locate the swivel tubes (28) and (40) in the meter bar (10) and with respect to one another.
