Control Flow HL2024® is our family of patent-protected products, designed to be installed either internally within a property or externally within the water meter chamber. ControlFlowHL2024® eliminates flow variations caused by pressure fluctuations in the supply system, delivering a controlled and steady flow with variations of less than 2%.
Unlike traditional flow regulators that simply restrict water flow, our devices are pressure-independent, designed to eliminate fluctuations and provide a steady, controlled flow of water. This unique technology allows users to achieve significant savings without having to change their normal water usage behavior.
