McCrometer, Inc. Announces NSF-61 And NSF-372 Certification For McPropeller Flow Meter

McCrometer, Inc., a globally recognized flow meter manufacturer, recently announced NSF-61 and NSF-372 certification for the Mc®Propeller flow meter.

The NSF-61 and NSF-372 certifications are international standards of approval for products, including flow meters, for safe use in drinking water flow applications. The Ultra Mag® and Dura Mag™ meters achieved NSF certification in 2021, and the FPI Mag® before that in 2019.

These approved meters, in the weld-on top-plate, main-line top-plate, and fixed ell styles join the group of existing certified mag meters, as well as the bolt-on saddle-style McPropeller, the M0300 series.
