0151E is a Brooks Instrument flow computer / secondary electronics product used with Brooks flow instrumentation. The official Brooks legacy listing identifies Models 0151E and 0151i as flow computers, and the Brooks installation manual describes the 0151E as the voltage-signal version with rate, total, setpoint, valve override, power-supply, and optional communications functions for connected mass flow equipment. Stored Sonisys auction records add useful context for used-condition pricing, enclosures, observed 0151E.10A and 0151AAE2A11A markings, and paired 5864E mass flow sensor listings
