  • (a) a housing having opposite intlet and outlet ends and a water guidance channel extending between said inlet and outlet ends and defining a direction of flow therebetween;

    (b) a main meter measuring inset disposed in said housing and defining a measuring volume disposed in-line with and across said water guidance channel, said main meter measuring inset including a hub;

    (c) a switch-over valve inset disposed in said housing across said water guidance channel and connected watertight to said main meter measuring inset; and

    (e) an impeller having an upstream side and a downstream side and being disposed in said housing across said water guidance channel such that at said upstream side said impeller is engaged by said hub of said main meter measuring inset and rotatably supported directly by said hub of said main meter measuring inset between said main meter measuring inset and said switch-over valve inset with said main meter measuring inset being disposed adjacent to said upstream side and said switch-over valve inset being disposed adjacent to said downstream side of said impeller relative to said direction of flow through said water guidance channel;

    (f) said main meter measuring inset also including an electronic scanning device disposed within said hub of said main meter measuring inset adjacent to said upstream side of said impeller for registering the rotational speed of said impeller.
