Electromagnetic flow-meter (EMF) McCrometer
Marsh Single-Mag

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 and any type of industrial flow processes involving conductive fluids such as potable water, slurries, sludge, cooling water, and pulp stock.
