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.
