Abstract
A turbine wheel meter for measuring the flow rate of a liquid, in particular water, is disclosed, with a measuring device, with an inlet and an outlet for the liquid to be measured, with a flow channel provided between the inlet and outlet, and with a turbine that has a turbine wheel with curved blades positioned in the flow channel, and wherein the turbine wheel cooperates with the measuring device to measure the flow rate of the liquid. A lower pressure loss and a high measurement sensitivity are achieved by embodying the turbine as a radial turbine with single-curved blades on the turbine wheel.

A turbine wheel meter for measuring a flow rate of a liquid, comprising:
- a measuring device;
- an inlet and an outlet for the liquid to be measured;
- a flow channel provided between the inlet and the outlet;
- and
- a turbine that is a radial turbine having a turbine wheel with single-curved blades positioned in the flow channel,
