ABSTRACT:
A fluid flow meter has a housing with a fluid inlet and a fluid outlet and defining therebetween a fluid flow path. The flow meter has a flexible membrane having a inlet end mounted at an inlet region of the fluid flow path and a outlet end mounted at an outlet region of the fluid flow path. The flexible membrane produces undulating motion in response to fluid flow in the fluid flow path. Fluid flow rate is measured by sensing the undulating motion of the membrane. Performance of the meter is enhanced by laminating a layer of material to the membrane.
