DPC mass flow controller Aalborg Instruments’ DPC series precision digital mass flow controllers provide accurate and stable control of mass flow rate, of process gases. Inherent simultaneous displays of Mass Flow, Volumetric Flow, Pressure and Temperature parameters promote applications in a variety of industries such as scientific and analytical applications, bioreactors and surface depositions, gas sampling, manufacturing and metrology activities.
