Smart system

As flow rate demand increases and overed the preset trip points, external motorized ball valves on each control valve are opened to bring the stand-by tank on-line to increase flow capacity. When the demand goes down below the trip points, the stand-by tank is taken off-line. When the capacity of a tank is depleted, it will immediately go into regeneration. The outlet valve will close to prevent any hard water from entering the service line. The tank standby will get into service at the same time.
