Portable metered flow apparatus for calibration/bump testing

A portable metered flow apparatus for accurately providing gas from a gas source, the apparatus comprising:

• a) a regulator having two opposing ends, a passageway that extends through the regulator between the two opposing ends, the first end of the regulator including a regulator inlet and the opposing end of the regulator including a regulator outlet, and a pressure regulator located in the passageway between the regulator inlet and the regulator outlet, the regulator inlet configured to be capable of being connected to the gas source and form a connection adapted to allow passage of the gas into the regulator,
• b) a gas delivery device comprising a hollow case having a case inlet and a case outlet and having disposed within said case:
• A) a valve having an entrance for the gas and an exit for the gas, the entrance for the gas configured to connect the valve to the regulator outlet, the valve adapted to be capable of allowing passage of gas through the valve when the valve is in an opened configuration;
• B) an electronic timing circuit operably connected to the valve and configured to open and close the valve, the electronic timing circuit configured to open the valve for a time interval and then close the valve after the time interval, wherein the electronic timing circuit is enclosed within the hollow case,
• C) a power delivery element adapted to power the portable metered flow apparatus,
• D) a power switch configured to be capable of activating the portable metered flow apparatus;
• and
• E) an activation trigger adapted to release the gas from the regulator, wherein the electronic timing circuit comprises a potentiometer and a potentiometer adjustment element.
