Patent ID: 8756990

Claim:
A flow sensor housing, comprising: a housing body including an inlet flow port and an outlet flow port, the housing body defining a fluid channel extending between the inlet flow port and the outlet flow port; a first region of the fluid channel defined by side walls, the first region positioned in and integrally molded with the housing body, wherein the side walls of the first region define a first cross-sectional area; a second region of the fluid channel defined by side walls, the second region positioned in and integrally molded with the housing body, the second region disposed immediately upstream or downstream of the first region, wherein the side walls of the second region are laterally spaced outward from the side walls of the first region and define a second cross-sectional area that is greater than the first cross-sectional area, and wherein an interconnecting surface extends between the side walls of the first region and the side walls of the second region; and flash integrally molded with the housing body and extending the side walls of the first region into the second region, wherein the flash, the interconnecting surface and the side walls of the second region collectively define a volume that is open to and with a space between the flash and the side walls of the second region, the space being in fluid communication with the fluid channel.
