Mass Flow Controller

The flox[on] mass flow controller was especially developed for use in heavy industry. The unique robustness and operational dependability of the design ensure maintenance-free operation and user-friendly controls with a maximum of load-bearing reserve. This makes it the ideal solution for pressure and flow regulation of gases in many fields of application.


Mass Flow Controller of flox[on] Series

Mass Flow Controller


The measurement of the flox[on] mass flow controller is temperature and pressure compensated with a very high control accuracy in the lower and upper flow ranges.

The adjustment control of the flox[on] mass flow controller uses a pressure compensated proportional valve of the most recent design, which makes it unsusceptible to pressure fluctuations in the in- and outlet.

The flox[on] mass flow controller is equipped with a high-performance micro-controller. This guarantees an unusually quick and dynamic regulation.
