Mass Flow Controllers & Meters

Multidirectional Gas Mass Flow Controllers

Multidirectional Mass Flow Controllers

Multidirectional mass flow controllers consolidate into one instrument what would otherwise require two or three separate devices. These instruments are able to control mass flow, volumetric flow, or gas pressure in both directions. There are many custom build options for bidirectional controllers, including anti-corrosive and low pressure drop options. Devices specifically tailored to stream switching applications are also available.

Check out the model pages for more product details and learn about our many custom build and performance options.
