ABSTRACT:
The disclosed gas flow sensor has an orifice connected in an oxygen conduit and a pressure switch connected to the conduit by having a pressure chamber communicating with the conduit. The chamber terminates at a diaphram which is operatively coupled to a normally open microswitch by a spring loaded rod. As the flow rate of oxygen flowing through the conduit drops below a permissible minimum magnitude, back pressure on the orifice decreases so as to close the microswitch to provide a control signal. A bypass valve is connected across the orifice to prevent the oxygen pressure within the conduit from excessively increasing.
