Abstract
A low flow injector controls remote delivery of low flows of gas. A higher flow carrier gas is provided by an MFC to a conduit. A remote flow restrictor is located to exhaust a critical process gas directly into the conduit. An electronic regulator controls a pressure of the critical gas responsive to a pressure point received from a controller corresponding to a desired mass flow. Also, a large flow restrictor vents the critical process gas.
