ABSTRACT:
A system for monitoring and controlling the delivery of CO2from a bulk storage tank to at least one gas-driven pump is disclosed. By monitoring certain conditions, the flow of CO2can be quickly and easily terminated if necessary, thereby reducing or eliminating undesirable consequences of CO2gas flow in abnormal operational scenarios. The invention is particularly well suited for deployment in conjunction with beverage dispensing machines and can be configured to shut down the flow of CO2if a drop in pressure occurs due to a leak in the system or if a syrup delivery system runs out of product.
