Abstract: A lower cost turbine flow meter comprised of an inner housing constructed out of a high permeable material surrounded by an outer housing constructed out of a lower cost, lower permeable material. A port is placed in the outer housing that runs down to the surface of the inner housing to detect the rotation of turbine rotors that rotate inside the meter as fluid or gas flows through the meter. A pickoff coil is placed in the port to generate a magnetic signal to penetrate through the inner housing wherein the turbine rotor vanes superimpose a pulse signal on the magnetic signal. The lower cost turbine flow meter can be used for any application for measuring fluid or gas, and may be used in a service station environment for measuring fuel or vapor in vapor recovery applications.
