Improved turbine comprising plural turbine blades supported by a turbine rotor of a flow meter, each turbine blade having a rounded leading edge, a feathered trailing edge, a convave top blade surface and a convex bottom blade surface, the turbine blade tapered from the leading edge to the trailing edge to form a hydrofoil shape defined by empirical profile date.

Flow meter turbine

Tubine rotor

A flow meter mounted in a flow delivery line and having a meter housing with a fluid opening and an electric counter. A turbine rotor supported on a turbine shaft is disposed in the fluid opening, the turbine having plural turbine blades with ferrous slugs embedded therein, the electric counter responding thereto for fluid delivery indication. Each turbine blade is tapered from front to rear into a feathered trailing edge and has a top concave surface along its length and a bottom convex surface. A pair of shaft supports, having fluid ports for washing about the turbine shaft, are provided to support the turbine rotor.
