A lower cost 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 a rotational component that rotates inside the meter as fluid or gas flows through the meter. A sensor is placed in the port to detect rotation of the rotational component through the lower permeable material inner housing. The lower cost 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.
