The Finetek SP Thermal Dispersion Flow Switch detects liquid flow by measuring temperature differences between two sensors—one reference sensor and one heated sensor. As fluid flows past the heated sensor, it cools, reducing the temperature difference and triggering the switch output. This precise thermal dispersion method ensures reliable flow monitoring and control in various industrial applications.

The Finetek SP Thermal Dispersion Flow Switch is available in several versions with choices of lengths, materials of construction and output types to meet a wide range of application requirements.
