Product Options


With a hard elastomer rubber lined bore, the MAG 5100W magflo meter is suitable for all water applications including those with very low flow rates. It can be used for DN25 to 1200 (1 inch to 48 inch). The kit is supplied as standard complete with integral grounding electrodes.

The hard lining guarantees consistent accuracy throughout the temperature and pressure range, whilst the soft elastomer facing provides high abrasion resistance and eliminates the need for gaskets. It is highly resistant to a wide range of chemicals.


The Siemens MAG 5100W is now MCERTS certified meeting the Environment Agency's performance requirements. View downloads for certificate.
