FLOW SENSOR

A flow sensor may include a housing including a body portion and a tube extending from the body portion. The body portion includes a chamber. A first, static pressure port and a second, stagnation pressure port are located along the tube. The first and second ports open in different directions about a periphery of the tube. A first, static pressure conduit fluidly couples the first, static pressure port of the tube to the chamber, and a first pressure sensor is configured to sense the fluid pressure in the chamber. A second, differential pressure sensor has a first port and a second port in the chamber. The first port of the second pressure sensor is configured to sense the fluid pressure in the chamber, and a second, stagnation pressure conduit fluidly couples the second, stagnation pressure port of the tube with the second port of the second pressure sensor. The first and second ports are disposed in a pipe having fluid flowing therethrough such that the second port is more exposed to the fluid flow relative to the first port. The fluid flow rate through the pipe is determinable based on the static fluid pressure sensed by the first pressure sensor, the differential pressure measured by the second, differential pressure sensor, the density of the fluid in the pipe, and the pre-determined diameter of the pipe.
