Abstract: Embodiments relate generally to methods and systems for filling a pressure sensor with a pressure transfer fluid, such as a gel, and preventing trapped air within the pressures sensor. A pressure sensor may comprise a substrate; a sense die mounted on the substrate; a housing configured to attach to the substrate over the sense die, wherein the housing comprises an opening to a hollow interior of the housing; and a gel material configured to fill the hollow interior of the housing and cover the sense die, wherein the housing comprises a plurality of shaped walls configured to direct the gel material as it fills the hollow interior of the housing.
