ABSTRACT:
A flow sensing device for measuring the rate of a gas flow. The flow sensing device includes a flow restrictor having at least one air flow annulus extending between the first and second end of the flow restrictor. Gas entering the flow sensing device at the inlet passes through the airflow annulus and exits the flow sensing device at the outlet. The flow restrictor causes a pressure drop between the inlet and outlet while promoting laminar flow therethrough. By measuring the pressure difference between the inlet and the outlet, the flow rate of the gas can be determined.
