Patent ID: 7650801

Claim:
A turbine flowmeter for measuring consumption of fluids, comprising: a housing with an intake, a discharge, and a flow tube; a counter for measuring and indicating the consumption; a turbine in the flow tube with a hub, a number of radial vanes mounted on the hub, and a substantially hemispherical front that faces the fluid flow; a holding insert made up of a water guide cross, which comprises a hub, radial struts that extend from the hub to a wall of the flow tube, a nozzle head that surrounds the front of the turbine so as to leave a gap through which the fluid flows, and a central opening in the nozzle head; an insert base body which includes a hub and radial struts that extend from the hub to the wall of the flow tube; and a device that detects revolutions of the turbine and transmits them to the counter, the vanes of the turbine being positioned close to the nozzle head, the turbine including a nozzle ring that joins the vanes and engages above an outer contour of the nozzle head so that a nozzle gap remains between the nozzle ring and the nozzle head, which the nozzle gap communicates with the gap formed by the nozzle head surrounding the front of the turbine.
