Marsh Multi-Mag™ flow meter

Ideal laboratory conditions are rarely found in any water system. Low flows, wide flow ranges, bends, elbows, and even the obstruction of the measuring device affect accuracy. The Marsh Multi-Mag Insertable Electromagnetic Averaging Flow Meter is truly a revolutionary instrument with unprecedented accuracy even in these most difficult flow conditions. It is ideal for measuring potable water, chilled water, raw water, water with sand and grit, and other debris-free water applications.

Until recently, expensive spool-piece mag meters, turbine meters, and other insertable flow meters that only provide a single point measurement were utilized. After years of extensive testing and thousands of installations worldwide, the patented Marsh Multi-Mag Flow Meter provides multiple measuring points precisely positioned according to your pipe’s size to making this the most accurate flow meter available. Typical applications include: custody transfer, filter balancing, filter backwash, water treatment processes, distribution management and head flows.

• Ideal for difficult flow conditions, i.e., low flows, wide flow ranges, bend and elbow installations, and vertical pipes
• Installs in minutes without system shut-down
• Automatic sensing and correcting for shifting flow profiles
• Streamlined sensor for minimal pressure drop
• High turn-down ratio
• Requires significantly less energy to operate than most flow meters
• Economical cost - doesn’t increase with pipe size
