GSx – smart mass flow meter and controller

The thermal mass flow meters of the Smart series GS are particularly suitable for quick measurement and control tasks in the field of apparatus engineering and plant engineering, as well as for specific OEM applications thanks to proven technology and standardized interfaces.


Communication with a PC or a PLC can be operated digitally as well as analogously. In addition, the GSx series is characterized by a number of other features, by which the devices can be optimized very easily to a variety of different requirement profiles. The GSx series is suitable for operating pressures up to 10 bar.
