The Multi-Mag flowmeter was tested by the Water Research Center, (WRc), a highly respected organization with strong ties to international regulatory, utility and industrial concerns.  The center was asked by several large water companies in England to evaluate the Multi-Mag sensors ability to obtain accurate flow rate information in ideal and non-ideal flow conditions. Marsh-McBirney performed admirably in all tests.  The final conclusion of the report is "The Marsh-McBirney Multi-Mag should be considered as a useful alternative to a full bore magmeter in many situations."

Additional Model 285 Product Information

Multi-Mag tests performed by the National Institute of Standards and Technology (NIST) verify that Marsh-McBirneys Multi-Mag consistently supplies accurate information according to the NIST standard.

Multi-Mag™s 1% accuracy specification has been verified by independent testing laboratories to assure you that we will meet our published accuracy specification.

Specifications

‧Proven electromagnetic sensor technology.
‧Ideal for difficult flow conditions, i.e. low flows, wide flow ranges, bend and elbow installations, and vertical pipes.
‧Ideal for potable water, raw water, cooling water, and water containing sand and grit.
‧Multiple measuring points tailored to your pipe size constantly profile the flow providing unsurpassed accuracy.
‧Installs in minutes without system shutdown.
‧Automatic sensing and correction for shifting profiles.
‧Streamlined sensor provides minimal pressure drop.
‧Drastically reduces operating costs. Requires significantly less energy to operate than most flowmeters.
‧Costs substantially less than most flowmeters whose cost increase substantially as pipe size increases.
