Abstract
An apparatus for controlling fluid flow and in particular fluid flow through a microfluidic multi-port control valve assembly of a High Pressure Liquid Chromatography (HPLC) unit. The flow control apparatus has a localized data repository for storing local valve position data and cumulative wear indications of components of the apparatus. The stored information travels with the apparatus allowing for more reliable predictive failure of components of the apparatus and translation of local valve position data for compatibility with host valve information. The translated valve position data enables determination of whether valve motion is acceptable and complete.
