Claim Text:
1. A sensor, comprising: a housing including a body portion and a tube extending from the body portion, the body portion including a chamber; a static pressure port and a stagnation pressure port located along the tube; a static pressure conduit fluidly coupling the static pressure port of the tube to the chamber; a first pressure sensor configured to sense the fluid pressure in the chamber; a second pressure sensor having a first port and a second port, the second pressure sensor being a differential pressure sensor, the first port of the second pressure sensor being exposed to the fluid pressure in the chamber; and a stagnation pressure conduit fluidly coupling the stagnation pressure port of the tube with the second port of the second pressure sensor, wherein, when the static pressure port and the stagnation pressure port are disposed in a pipe having fluid flowing therethrough such that the stagnation pressure port is oriented to be more exposed to the flow relative to the static pressure port, a fluid flow rate through the pipe is determinable based on a static fluid pressure sensed by the first pressure sensor, a differential pressure measured by the second pressure sensor, a density of the fluid in the pipe, and a pre-determined diameter of the pipe.
