OMEGA™ FMA7400/7500 (elastomer seal) and (-SS) (metal seal) thermal mass flow meters and controllers achieve unprecedented performance, reliability, and flexibility in many gas flow measurement and control applications. The FMA7400/7500 is designed to overcome a long-standing limitation of many thermal mass flow units when changing gas types, a simple correction factor, such as the ratio of heat capacities between the calibration gas and new gas, cannot account for accuracy robbing viscosity and density differences.
The Omega FMA7400/7500 database is built on thousands of native gas runs to establish correction functions that account for both thermal and physical differences among gases making the FMA7400/7500 series among the most accurate and flexible mass flow designs available today. The FMA7400/7500 series is the perfect choice for customers who use thermal mass flowmeters or controllers on a variety of gases, who need to change gas type frequently, or who need to re-range while preserving gas measurement and control accuracy.
The Omega FMA7400/7500 series features a corrosionresistant Hastelloy® C-22 sensor for durable, long-term operation. Settling time is less than a second and full scale accuracy is 1%, this ensures that the FMA7400/7500 will provide reliable flow measurement or flow control in demanding gas flow applications. Both FMA7400/7500 and the (-SS) version achieve excellent internal to external leak integrity for challenging process gases as found in CVD, solar, and other processes.
A major advancement over traditional single point gas conversion factors, Omega delivers up to a three times improvement in process gas accuracy. This is achieved through advanced gas modeling plus extensive actual gas testing protocols that provide extremely accurate compensation. This also allows the device to be quickly and easily configured for another gas and/or flow range without sacrificing accuracy or range-ability. Selecting a new gas automatically creates a new calibration curve, establishes optimized PID settings for dynamic control, compensates for gas density and viscosity effects, and ensures smooth, overshoot-free transitions between flow rates with excellent steady state stability supplying unparalleled flexibility. Re-programming is simple and fast; a new gas and range can be programmed in under 60 seconds.
