Abstract
Flow sensor includes a housing having a chamber and a tube extending therefrom. Static and stagnation pressure ports are located along the tube and open in different directions about a periphery. A first conduit fluidly couples the static pressure port to the chamber, and a first pressure sensor senses the fluid pressure in the chamber. A differential pressure sensor has a first port and a second port in the chamber. The first port senses the fluid pressure in the chamber, and a second conduit fluidly couples the stagnation pressure port with the second port. The second port is more exposed to fluid flow through the pipe relative to the first port. Fluid flow rate through the pipe is determinable based on static fluid pressure sensed by the first pressure sensor, differential pressure measured by the differential pressure sensor, density of fluid in the pipe, and diameter of the pipe.
