Marsh Single-Mag™ flow meter

The Marsh Single-Mag Flow Meter is an insertion-type device that provides a highly cost-effective solution for the accurate measurement of liquid flow in closed conduit, pressurized pipe applications. Unlike conventional magnetic meters, the Single-Mag’s cost is independent of pipe size. Velocity and pipe diameter information are utilized by the Single-Mag to determine flow over wide flow ranges with a high degree of accuracy.

The Marsh Single-Mag reliably measures flow in water and wastewater as well as any type of industrial flow processes involving conductive fluids such as potable water, slurries, sludge, cooling water, and pulp stock. 

  • Supports pressurized line sizes from 2 to 96 inches (50-2500 mm)
  • Accuracy: ±2% of reading ± zero stability at -3 to +10 ft/s (-0.9 to +3 m/s)
  • Wide flow range: -5 to +20 ft/s (-1.5 to +6.1 m/s)
  • 4-20 mA output signal
  • Proven electromagnetic technology based on Faraday’s Law
  • Debris shedding, self cleaning sensor eliminates costly maintenance
  • Cost is independent of pipe size.
  • Easy installation/no interruption of flow process
  • Special sensors for harsh environments
