PROBLEM TO BE SOLVED: To provide a duplex meter unit which holds rigidity even if the connection stress of a water supply meter and stress caused by ground displacement act on the unit, and a duplex meter unit frame.SOLUTION: A duplex meter unit includes: a piece of branch piping 1 having a primary-side one flow-in pipe part and a plurality of branch pipe parts whose secondary-side piping shafts are parallel with each other; a plurality of pieces of primary-side piping 4 which are the pieces of primary-side piping 4 constituted so as to be connectable to the branch pipe parts, and are arranged at the same number as that of a plurality of the branch pipe parts, and a plurality of pieces of secondary-side piping 5 which form an attachment/detachment part of a water meter between the primary-side piping 4 and themselves, and are arranged at the same number as that of the plurality of pieces of primary-side piping 4; and a meter box capable of storing the branch piping, the primary side piping, and the secondary side piping, and capable of fixing the primary side piping 4 and the secondary side piping 5 in a state that the branch piping 1 and the secondary side end part of the secondary side piping 5 are positioned outside of the frame 3 and the attachment/detachment part is positioned inside the frame 3.SELECTED DRAWING: Figure 6 |
