Dwyer Instruments TDFS2-2-P-06 Thermal Dispersion Flow Switch

The Dwyer Instruments TDFS2-2-P-06 Thermal Dispersion Flow Switch is designed for pipe sizes from 2 inches to 10 inches. This non-mechanical switch measures the flow rate, based on the temperature differential and is less prone to the damage. It is widely used in HVAC applications such as boiler flow proving and liquid transfer applications. The advantages are low pressure drop across the valve, ease of field adjustment of the flow rate and long service life due to construction from 316 stainless steel. This switch which improves the efficiency and reliability of the system.
