Massflow controllers
Typical fluid massflow controllers support serial or LAN interface to be steered by suitable protocol using Labview or other corresponding software.
As an alternative, we designed a stand-alone electronic unit with the following features:
-
Manual setting of the massflow value; the set point is shown by the embedded LED display
-
Robust stand-alone operation
-
To drive more than one mass flow controllers upon customer request
-
Embedded protection circuits: emergency stop of flow actuated by alarm signal supplied from external input or embedded gas leak detector system
