Abstract
Fluid flow meters and methods for measuring different aspects of fluid flow with a non-contact sensor are provided. In some cases a fluid flow gear meter is provided with a fluid chamber that is sealed with a cover portion carrying the non-contact sensor. An optional separation member may be located between the cover portion and the chamber to seal the chamber. In some cases the cover portion and/or separation member are configured to transmit visible light to allow viewing of the fluid chamber, through material selection and/or the presence of viewing cavities within the material. The flow meter is optionally configured to prevent or reduce the transmission of ambient environmental radiation into the flow meter to lessen the likelihood that it may adversely affect an optical non-contact sensor used to detect movement of gears within the chamber.
