Guide to Mass Flow Controllers: Precision in Flow Applications

In the realm of flow applications, accuracy and control are paramount. Whether you’re dealing with critical industrial processes, sophisticated medical equipment, or cutting-edge research laboratories, the need for precise flow regulation cannot be overstated. Enter the solution that meets and exceeds these demands: Kelly Pneumatics, Inc.’s Proportional Valve Driven Mass Flow Controllers. Designed for a wide array of applications requiring exact, linear mass flow control, these controllers are at the forefront of innovation and efficiency. This comprehensive guide delves into the variety of use cases for Kelly Pneumatics Mass Flow Controllers and extensively defines their functions, showcasing why they are an indispensable asset for your flow control needs.

Unparalleled Precision Across the Board

Kelly Pneumatics’ Mass Flow Controllers are engineered to offer supreme accuracy and versatility. With two distinct models tailored for high and low flow applications, these controllers ensure optimal performance in diverse environments. The High Flow Version stands out for its ability to maintain an impressive 1% full-scale accuracy for flow rates ranging from 0 to 300 Liters Per Minute (LPM). For applications where even greater precision is essential, this unit can be customized to achieve 2% of reading accuracy for flow rates above 2.5 LPM. On the other hand, the Low Flow Mass Flow Controller offers exceptional accuracy of ±0.5% Full Scale or ±2% of reading for flow rates between 0 to 10 LPM. Such precision makes these controllers highly sought after in applications where even a minor discrepancy in flow can have significant consequences.

Robust Against Variabilities

One of the standout features of the Kelly Pneumatics Mass Flow Controllers is their robustness against environmental and process variabilities. They are designed to adjust for back pressures of up to 100 psig, a critical feature for maintaining accuracy in systems where back pressure fluctuations are common. Additionally, these controllers are adept at compensating for changes in gas temperature, ensuring that flow control remains consistent and accurate even under varying temperature conditions. This adaptability is essential for processes that are sensitive to temperature changes, providing peace of mind and reliability.

A Spectrum of Applications
