Name: Festo 538423 Flow sensor MS6-SFE-F5-N2I-M12
Brand: Festo

Flow sensor MS6-SFE-F5-N2I-M12

The Festo 538423 is an industrial component utilizing a thermal measuring principle with heat loss measurement methods to monitor flow rate and consumption in a unidirectional P1 to P2 direction. It operates within a flow rate measuring range of 200 to 5,000 l/min, a working pressure of 0 to 16 bar, and ambient and medium temperatures from 0 to 50 °C using air quality class 5:4:3 per DIN ISO 8573-1 or nitrogen. Featuring an accuracy of +/- (3% o.m.v. + 0,3% FS), two NPN switch outputs, and compatibility with the EU-EMV guideline, this CE-marked device provides precise switching and analog values.

Engineering context

Identification and RFQ Guidance

Confirm the exact configuration

Use the manufacturer part number and model code—not appearance alone. Connection, size, material, voltage, pressure, seal, and control options can differ within the same product family.

What to include in your RFQ

Provide quantity, delivery country and ZIP/postal code, required condition, target date, and photographs of the existing nameplate when available.
