FG4000 - electromagnetic flow meter



FG4000 - electromagnetic flow meter

The FG4000 magnetic flow meter is primarily designed for a wide range of industrial applications. Flow is determined on the electromagnetic induction principle that allows measuring it without any mechanical parts in the metering profile, which results in virtually no pressure drop.

The FG4000 flow meter is a highly reliably instrument that offers accurate flow measurement in liquids at long-term stability. This flow meter further features awide flow range while maintaining measurement accuracy with fast response to flow fluctuations. An alphanumeric display and three membrane keys provide comfortable operation. Last but not least, accent is put on design user-friendliness, such as easy access to the connectors.

The basic structure comprises a rigid aluminium casting that allows four positions of the flowtube in a horizontal or vertical pipe line while the correct operation position of the stainless steel front panel with display and membrane keys is always provided. The FG4000 flow meter advanced industrial design satisfies stringent requirements for mechanical as well as chemical resistance thus allowing to use the instrument under most rigorous conditions. The flow meter has ingression rating IP67 while its increased resistance against electromagnetic interference in compliance with category E2 pursuant to EN ISO 4064-5 may be stressed.
