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 comprises: a piece of branch piping 1 having a primary-side one flow-in pipe part 1a and a plurality of branch pipe parts 1b whose secondary-side pipe shafts are parallel with each other; a plurality of pieces of primary-side piping 4 which are the primary-side piping 4 constituted so as to be connectable to the branch pipe parts 1b, and are arranged at the same number as that of a plurality of the branch pipe parts 1b; and a plurality of pieces of secondary-side piping 5 which form an attachment/detachment part of a water meter M 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. In a frame being the rectangular frame 3, the branch piping 1 and a secondary-side end part 5b of the secondary-side piping 5 are located outside the frame 3, and the duplex meter unit comprises the frame 3 which is constituted so as to be capable of connecting the primary-side piping 4 and the secondary-side piping 5 in a state that the attachment/detachment part is located inside the frame 3. |
