Provided is a gauge mandrel, a sensing system, and a well system. The gauge mandrel, in one aspect, includes a housing having a length (Lt), the housing having a main section and an upset section extending outward from the main section, and a primary fluid passageway located in the main section of the housing and extending along the length (Lt). In accordance with this aspect, the primary fluid passageway includes an uphole tubing coupling having an uphole tubing coupling centerline (CLTU) and a downhole tubing coupling having a downhole tubing coupling centerline (CLTD). In further accordance with this aspect, the uphole tubing coupling centerline (CLTU) and the downhole tubing coupling centerline (CLTD) are offset from one another by a distance (DT). The gauge mandrel may further include a gauge cavity located in the upset section of the housing and extending along at least a portion of the length (Lt).
