Abstract
A gas manifold that provides an uninterrupted supply of gas and automatically switches between at least two gas sources. This gas manifold couples to a on-line gas source and a reserve gas source. A pressure transducer at the inlet to the manifold reads the pressure of the gas source. A downstream pressure regulator of each pressure transducer regulates the pressure of gas supplied to a control valve directed by a control circuit. This control circuit monitors the pressure read by the pressure transducers to determine which gas source will be placed on service depending on user preferences, and directs the operation of the control valve to effect those choices.
