Flow sensor dn20 bsw 6-15 De Dietrich 7306729

Accurate water flow measurement is key to optimizing boiler performance and ensuring efficient heat transfer. This flow sensor dn20 bsw 6-15 is a component that monitors the flow rate of water through the heating system, providing data to the boiler's control board for modulation and safety functions. Designed for pipes with a nominal diameter of DN20, it is suitable for a range of residential and commercial boilers. The sensor works by detecting the movement of water and sending a signal proportional to the flow rate. If your boiler displays error codes related to flow or fails to ignite, a faulty flow sensor may be the issue. Replacing it with this part helps restore accurate flow monitoring and efficient operation.
