Description
The Lochinvar & A.O. Smith 100275528 Flow Sensor is a monitoring component to detect and measure water movement within boiler and heating equipment control systems. It operates by sensing flow activity through the internal passage and transmitting corresponding signals to the control board, allowing the system to regulate heating operation and circulation sequences accurately. Positioned in condensing boilers, water heating units, and industrial HVAC systems, the sensor is installed within the water line or designated sensing port during maintenance or replacement procedures. Accurate flow detection supports controlled system operation, responsive heating performance, and protection.
