The Siemens SITRANS FM MAG 5100 W is a mains-powered electromagnetic flow sensor engineered specifically for potable water, raw water and wastewater applications. Paired with a MAG 5000/6000 or MAG 6000 I transmitter, it is available in both AC and DC supply versions and delivers accurate, maintenance-free volume measurement across a very wide size range with full drinking-water approvals.

Features & Specifications

• Electromagnetic induction measuring principle with pulsed-field, mains-synchronised excitation (50 Hz / 60 Hz)

• Nominal size DN15–DN300 (½”–12”) coned sensor and DN25–DN2000 (1”–78”) full-bore versions

• Process connections to EN 1092-1 (PN10, PN16, PN40), ANSI B16.5 Class 150, AWWA C-207, AS4087 and JIS B2220
