Abstract

A method for determining an actual gas flow rate as gas flows through a gas flow delivery system is provided. The method includes sending the gas through the gas flow delivery system into a gas conduit, wherein a section of the gas conduit is widened to form an orifice. The method also includes pressurizing the gas to create a choked flow condition within the orifice of the gas conduit. The method further includes measuring upstream pressure of the gas via a set of pressure sensors. The method yet also includes calculating the actual flow rate based on the upstream pressure of the orifice of the gas conduit.
