Low Pressure Drop Mass Flow Meters and Contro-L-BS

Low Pressure Drop Mass Flow Meters and Controllers – The Whisper Series

So little system impact it can run on just a whisper

Low pressure drop minimizes system impact, enabling flow measurement and control at near-atmospheric pressures, perfect for aerospace and environmental gas analysis applications. Reduced pressure drop also means more process fluids go into your process and not into your measurement devices.
