3.2
Design
The SITRANS FM MAG 5100 W is an electromagnetic flow sensor designed to meet the
requirements in ground water, drinking water, waste water, sewage or sludge applications.
With its coned design, increased low-flow accuracy is achieved making it especially useful for
leak detection. It is suitable for direct burial and constant flooding. MAG 5100 W complies with
drinking water and custody transfer approvals.
