• Designed for laboratory, OEM, industrial automation, semiconductor, analytical instrumentation, gas blending, and research applications.

About Omega Gas Mass Flow Controllers:Omega FMA5400A and FMA5500A Series mass flow controllers are precision instruments designed to accurately measure and automatically regulate gas flow in demanding laboratory and industrial applications. Using thermal mass flow sensing technology, they measure gas mass flow directly rather than volumetric flow, providing stable and repeatable control without requiring compensation for normal temperature or pressure changes within the specified operating limits.These controllers are commonly used in semiconductor manufacturing, analytical laboratories, environmental monitoring, gas mixing systems, fuel cell research, leak testing, calibration equipment, biotechnology, pharmaceutical production, and OEM process control equipment where precise gas delivery is critical. The integrated proportional control valve continuously adjusts flow to maintain the desired setpoint while supporting both local and remote operation.Please verify the model number, calibrated gas, flow range, process connections, power requirements, control signals, and output configuration before purchasing to ensure compatibility with your application.
