Flowmeter handles difficult municipal, industrial water applications

June 14, 2006

The Marsh Multi-Mag™ Flowmeter is an advanced measurement solution that provides accuracy in the most difficult flow conditions—low flows, wide flow ranges, flows containing sand and grit, vertical pipes and locations near bends and elbows. It measures liquid volumetric flow rates in pipes sized from 4 to 120 inches with a streamlined multi-point technology that creates only negligible pressure loss. It is also available for 1-, 2- and 3-inch taps. Using an insertable electromagnetic averaging design, McCrometer’s Multi-Mag measures volumetric flow with accuracy up to ±1 percent of reading and repeatability at 0.20 percent of flow range. It is ideal for a wide range of applications including custody transfer, filter balancing, filter backwash, water treatment processes, distribution management and well head flows. Additional benefits include a high turndown ratio, automatic sensing and correction for shifting profiles, and reduced operating costs due to its significantly lower energy requirements compared to most flowmeters.
