Thermal Flow Switch

Thermal Flow Switch

Thermal Flow Switch

Real-time Flow Monitoring: Provides instant monitoring of liquid flow status and provides signal output to prevent critical issues like pump dry-running.

No Moving Parts Design: Based on thermal diffusion principles with no mechanical wear, ensuring high reliability and a long service life across diverse industries

Intuitive LED Status Display: Features a 6-LED indicator (Red, Yellow, Green) to clearly visualize flow velocity relative to the setpoint at a glance.

Wide Media Compatibility: Versatile enough to monitor water 0.03~3m, oil :0.03~3 m/s, and gases: 2~20 m/s.

Easy Alarm Setpoint Adjustment: Users can conveniently set flow alarm points by simply turning an internal adjustment knob under the protective screw.

Durable & Industrial Build: Constructed with a 304 stainless steel probe and IP67-rated protection, suitable for demanding environments like petrochemical and water treatment.
