Abstract

A plural component dispensing system includes at least one compressed gas pneumatically connected to supply pressurized gas to each of a first pressure vessel that discharges a first fluid component and a second pressure vessel that discharges a second fluid component. Each of the first fluid component and the second fluid component is supplied from the respective pressure vessel through individual flow meters to a device. A first pressure regulator is pneumatically connected between the first pressure vessel and the at least one compressed gas source to regulate pressure of the first pressure vessel. A controller receives sensed first and second volumetric flow rates from the individual flow meters and controls the first pressure regulator based on the sensed volumetric flow rates to produce a target ratio of the first fluid component and the second fluid component at the device.
