Ideal For Airports and Bases, Building Roof-Tops, Construction Sites, Industrial Plants, Public Parking Structures & Lots, Roadways & Bridges and School Districts

Facility and infrastructure engineers responsible for pollution and flood control will find the advanced Marsh Multi-Mag™ Flow Meter from McCrometer provides a reliable, scalable and economical solution to measuring and monitoring highly variable flows of stormwater run-off.

Stormwater and snowmelt run-off are a public environmental concern subject to state and federal agency clean water regulations designed to protect the nation’s streams, rivers and lakes. Run-off that comes into contact with impervious surfaces such as professional buildings, parking lots or roads causes both pollution and flood control problems. These liquid flows are widely variable and unpredictable, which makes measuring and monitoring them a challenge for conventional single-point flow meters.

The innovative Multi-Mag Flow Meter is an advanced multi-point measurement solution that provides unprecedented accuracy in the most difficult flow conditions—such as low flows, wide flow ranges, and flows containing sand and grit. It measures liquid volumetric flow rates in pipes sized from 4 to 120 inches (100 mm to 3000 mm) with a streamlined multi-point technology that creates only negligible pressure loss.

Using a unique insertable electromagnetic averaging design, the Multi-Mag measures volumetric flow with accuracy up to ±1% of reading (from 0 to +20 feet/second + zero stability) and repeatability at 0.20 percent of the flow range.
