First Claim
1. A compound water meter, comprising:
- (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.

Abstract
A compound water meter includes a housing having opposite inlet and outlet ends, a water guidance channel extending between the inlet and outlet ends and defining a direction of flow therebetween and upper opening disposed above and in communication with the water guidance channel, a main meter measuring inset disposed in the housing across the water guidance channel, a switch-over valve inset disposed in the housing across the water guidance channel and connected watertight with the main meter measuring inset, and an impeller rotatably supported directly by and between the respective insets such that the main meter measuring inset is disposed upstream and the switch-over valve inset downstream of the rotatable impeller relative to the direction of flow. Both insets form an inset unit and with the impeller are suspended in the housing by a cover which closes the upper opening of the housing. The main meter measuring inset has a hub rotatably supporting the impeller. The compound water meter also includes an electronic scanning device for registering the rotational speed of the impeller which is disposed within the hub and an electronic counter disposed on the housing cover which is connected via leads with the electronic scanning device.
