ELECTROMAGNETIC FLOW METERS

FG4000 – Basic Information

The FG4000 electromagnetic flow meter is designed for a wide spectrum of industrial applications. An electromagnetic inductance principle is utilized to determine flow velocity. This allows measurement that excludes mechanical parts in the flow metering section thus eliminating pressure drop.

It is a high reliability instrument offering accurate metering of flows of liquids with long-term stability. The flow meter can further measure a wide range of flows while maintaining the accuracy, fast response to changes in flow, comfortable operation (using display and membrane keys), and, last but not least, user-friendly design (such as easy access to interface connectors).

Its central part is a sturdy aluminium casting whose design allows four different positions in a horizontal or vertical pipeline for convenient access to the stainless steel front panel with display and membrane keys. The advanced industrial design of the FG4000 line of flow meters meets stringent requirements on mechanical and chemical resistances enabling to use these instruments even under most difficult conditions. The flow meter is certified for enclosure rating IP67 while its high resistance against electromagnetic disturbance at the level of class 2 as specified in EN 14154 should be highlighted.
