Abstract
A bulk tank source of pressurized gas supplies gas to a consumption device, such as a beverage dispenser. A control valve is located between the bulk tank and the consumption device. A pressure monitoring system is connected to monitor the gas pressure between the bulk tank and the control valve. The pressure monitor system closes the valve when pressure drops below a first predetermined threshold, and opens the valve when the monitored pressure exceeds a second predetermined threshold greater than the first predetermined threshold.
