A flow controller which is commonly referred to as a "mass flow controller" is a device designed to regulate the flow of liquids, gases, or other materials in a system. It ensures that the flow rate remains within desired limits, which is crucial for maintaining system efficiency and safety. Flow controllers can be found in various industrial applications, including industrial processes, water treatment systems, and HVAC systems.
The fluid enters from the inlet and flows through the sensor or the bypass. The sensor then detects the mass flow rate as a relative change in temperature and converted to an electric signal. This signal passes through the amplification, correction and comparison control circuits and put out as a voltage reading (e.g. 5V).
The comparison control circuit compares the flow rate electric signal to flow rate setting and sends the difference between the two readings to the valve driving circuit. Finally, the flow rate valve moves to adjust the flow rate actual to the flow rate setting so the flow controller is set to the correct level.
