SU Puresonic flowmeter: Select products

The SU line of ultrasonic flow meters from ifm cover a wide variety of industrial applications with the added benefit of real-time data via IO-Link. Browse our models below to find the one that's right for your application or explore the SUH line of sanitary product numbers.

The SUxx2x series is compatible with 90% of conductive and non-conductive water media. The SUxx3x series supports 35% glycol solutions and oils with viscosities from 7 to 68 mm²/s at 40°C. The SUxx5x series are blind ultrasonic transmitters (8–32 VDC) suitable for water, glycol, and oil, featuring a configurable analog output (4–20 mA, 0–10 V, or 0.5–4.5 V). All SU models include a totalizer output for consumption monitoring.
