Flow control systems are mechanisms used to manage the movement of fluids, gases, or other materials within a system. They ensure that the flow rate, pressure, and direction are maintained at desired levels, which is crucial for the efficiency and safety of various processes. Common applications include water supply systems, HVAC systems, and industrial processes. These systems often utilize components such as valves, pumps, and sensors to regulate flow. By adjusting these components, operators can control the flow based on real-time data, ensuring optimal performance. Effective flow control is essential in industries like oil and gas, water treatment, and manufacturing.
