Calorimetric-principle flow switches use the cooling effect of a flowing fluid to detect flow rates of liquids and gases. These units have no moving parts that can break off or stick, and compensate for temperature changes in the fluid stream. The switches have a temperature response rate that allows the switch to accurately monitor the flow of cooling water to welding equipment, transformers, and other applications that experience rapid temperature changes.
