Dual Valve Mass Controller Operating Notes
The MCD is a versatile Dual-Valve Mass Flow and Pressure Controller. It can be used to:
•
Measure mass flow and volumetric flow in both directions, plus absolute
pressure and temperature;
•
Control mass or volumetric flow from a pressurized source or to vacuum;
•
Control absolute pressure or back-pressure in a flowing process;
•
Control absolute pressure in a closed volume with automatic venting.
Application examples are shown below and on the following page. Please contact
