The GEMU 3030 mFlow flowmeter operates according to the magnetically inductive measurement principle. It is suitable for electrically conductive media and enables exact measurement of flow velocities and flow rates of inert and corrosive liquids. The simple mechanical construction of the GEMU 3030 mFlow magnetically inductive immersion-type flowmeter offers quick and easy installation.
The device has a backlit display and is operated via a membrane key-pad at the front of the housing. Electrical connections are on the rear.
