Electronic pressure controller for gases
with integrated flow measurement

The new electronic red-y smart pressure controllers combine the reliable technology our of thermal mass flow controllers with electronic pressure control.
The devices automatically control a predefined process pressure and at the same time measure and/or limit the flow rate.
On-the-fly switching between pressure control and flow control offers maximum flexibility.
