SMF sanitary magmeter: Select products

The SMF line of magnetic-inductive flow meters from ifm cover a wide variety of applications with the added benefit of real-time data via IO-Link. All SMF part numbers offer the same output functionality, including 4–20 mA analog, pulse, diagnostics, fluid detection, flow direction, totalizer switching, and an input for external totalizer reset. Browse our models below to find the one that's right for your application. Then, browse our customer use cases for testimonials on the SMF's success. 

Please note: To complete the sanitary flow meter solution, you must select and purchase a compatible process adapter and gasket in addition to the flow meter. All components are sold separately.
