Uf 821 G

This flow meter, especially adapted to gas measurements even in difficult conditions, offers results that are accurate and stable over time. It has comprehensive functions and can have up to 4 chords for enhanced measurement precision. You can also add up to 4 input/output modules adapted to your application. Compact and robust, it has a hinged lid for easy access to the connection zone.
