Abstract
A flow node includes characterized restrictor in series and adjacent with a valve to provide a primary flow restriction with a minimized volume between the two. A conductance of the characterized restrictor is low enough relative to the valve seat to cause a pressure drop that is sufficiently large relative to the pressure drop across the valve seat that a pressure measurement device is located upstream of the valve is used to determine the pressure to the inlet of the restrictor. A vent can be included to reduce bleed time. Multiple flow nodes in parallel increase a dynamic range.
