Potterton 12L Flow Meter 720778401

Potterton 12L Flow Meter (720778401) The Potterton 12L Flow Meter is a high-precision internal sensor used to monitor and regulate the domestic hot water (DHW) circuit. Its primary role is to detect water movement when a tap is opened, sending an electronic signal to the boiler's control board to initiate the hot water ignition sequence. This specific 12-liter variant is calibrated for mid-range flow capacities to ensure consistent temperature delivery. Flow Sensing Accuracy: Provides real-time data to the PCB for precise modulation of the burner based on water demand. Corrosion-Resistant Design: Manufactured with high-grade synthetic materials and robust seals to withstand constant exposure to fresh water. Hydraulic Reliability: Engineered to replace part number 720778401, ensuring a direct fit within the hydraulic manifold. Efficient Performance: Helps resolve issues where the boiler fails to fire for hot water or provides fluctuating water temperatures.
