Description
The Lochinvar & A.O. Smith 100278304 Flow Switch is a sensing component used in water heating systems to monitor the presence and rate of fluid flow. It is installed in boilers, water heaters, and hydronic heating circuits. The switch activates or deactivates system operation based on adequate water movement, helping prevent dry firing and overheating conditions. It is used in circulation lines to ensure safe startup and continuous operation of heating equipment. During install, and maintenance, it supports system protection by confirming proper flow before burner or heating elements engage.
