US Patent 11573580 Systems and methods for turning over fluid distribution systems

A manifold can determine a turnover scheme including a target turnover schedule of target turnover levels, based on an operation schedule and efficiency setting for a fluid distribution. Each target turnover level can correspond to a volume of fluid to be cycled through the fluid distribution system over a period of time. The manifold can operate respective valves and a supply device based on a target turnover level and determine a current turnover level from a flowrate detected by a flow sensor for at least one of the valves. The manifold can receive a current usage of the fluid distribution system and determine a required turnover level. An override status for the turnover scheme can be based on the efficiency setting and a comparison of the current, target, and the required turnover levels, and the manifold can operate respective valves and the supply device based on the override status.
