INLINE Flowmeter for Continuous Flow Measurement

SE30 For use with fitting S030, DN15-50 mm

• Turn & Lock bayonet fitting isolates
sensor from media
• Economic integration in pipe systems
• 3-wire frequency version for direct
connection to PLC (PNP and NPN)
• Connection to Bürkert evaluators in
remote versions
Please see fitting S030

Unique bayonet style flow meter constructed from an SE30 sensor and an Envelope Dimensions [mm] (see datasheet for details)
S030 flow fitting. Perfect for neutral, solid free liquids. A hall-effect sensor
produces a square wave frequency proportional to the flow rate.
