What Is a Liquid Flow Controller?
A liquid flow controller is a precision device designed to regulate the flow rate of liquids and gases in various industrial processes.
This device employs one of three primary operational principles: the control valve method, the orifice method, and the rotary method. Each method offers distinct advantages in terms of structural complexity, control accuracy, and cost-effectiveness. Liquid flow controllers are integral to a wide range of industries, including chemical production, food processing, healthcare equipment, semiconductor fabrication, automotive, and energy sectors. They are typically comprised of sensors for flow measurement, controllers to process the sensor data, control valves to adjust the flow, and actuators to operate the valves.
The control valve method modifies flow rates by altering the valve’s opening, providing a straightforward, economical solution albeit with limited precision. The orifice method achieves flow regulation by introducing an orifice plate within the flow path, a cost-effective approach that may vary with flow conditions. Conversely, the rotary method utilizes a rotating element to finely adjust the flow, delivering high accuracy at a higher cost and with greater structural complexity.
