Industrietechnik SF6E Liquid Flow Switch | Brass | Low-Flow | R1" Tee Mount | IP65 | CE Certified

Low-Flow Monitoring for HVAC and Light Industrial Applications

The SF6E from Industrietechnik is a low-flow electromechanical liquid flow switch designed for precision monitoring in heating, cooling, and industrial process systems. With a compact body and an adjustable flow setpoint range of 0.2 to 1 m³/h, this switch is ideal for systems that require reliable detection of smaller flow rates.

Built with a brass housing and R1" Tee fitting, the SF6E is easy to install in existing pipelines, making it ideal for retrofits or new builds in HVAC, water circulation, or pump monitoring systems. It features a high electrical contact rating and an IP65-rated enclosure with a transparent PC cover for visibility and durability.

Whether you're safeguarding against pump dry-run or monitoring return flow in low-demand loops, the SF6E provides a cost-effective, robust solution compliant with CE standards.
