US Patent for Pressure based mass flow controller Patent (Patent

A mass flow controller (MFC) has a standard envelope with an enclosure and a corresponding base. A pressure transducer is communicatively coupled to a process gas in a proportional inlet valve without being physically coupled to the base. The space formerly occupied by the pressure transducer is available for additional component integration, or reduction of the standard envelope size.
