Saunier Duval Sensors

This boiler part detects if water is moving through the Saunier Duval boiler. If these sensors are detecting water flow they can either be a pump proving flow sensor or a domestic hot water flow sensor which detects if a hot tap has been opened. All these Saunier Duval flow sensors send signals to the printed circuit board within the boiler ensuring they are being monitored all of the time.
