Overview: What Is a Mass Flow Controller?
A mass flow controller (MFC) is a highly precise device used to measure and regulate the flow rate of gases or liquids. MFCs are widely used in semiconductors, laboratories, pharmaceutical processing, industrial automation, energy systems, environmental monitoring, chemical injection, and fuel-cell technology.
Most MFCs are designed to:
- Provide high-accuracy flow measurement
- Automatically control flow rates in closed-loop systems
- Ensure repeatability under varying pressure and temperature conditions
- Support multiple communication protocols (analog, RS-485, Modbus, DeviceNet, etc.)
Given the wide range of applications, selecting reliable flow controller manufacturers in USA ensures compliance with industry standards, timely support, and high-performance system operation.
