ELECTRONIC PRESSURE GAUGE FOR PRESSURIZED SYSTEM WITH VARIABLE OUTLET FLOWS

Document Type and Number:

WIPO Patent Application WO/2017/165414

Kind Code:

A3

Abstract:

A pressure gauge system for a tank with a variable flow rate that provides a user with an indication of how much usable time is left in a pressurized gas tank given a particular selected flow rate or operational condition and what pressure of gas of left in the tank. The system comprises a gas cylinder containing a gas; a gas outlet connector; a regulator in fluid communication with the gas cylinder and the gas outlet connector, the regulator controlling the rate at which the gas flows from the gas cylinder to the gas outlet connector; a selector knob for selecting a flow rate from a plurality of flow rates; a spring plunger connected to the selector knob and having a position corresponding to the selected flow rate; a potentiometer detecting a location of the spring plunger; and a processor configured to receive from the potentiometer a signal indicating the location of the spring plunger, detect the selected flow rate, and cause the detected flow rate to be displayed on a display.
