AIRGAS will be offering a virtual demonstration of its patented AcuGravâ„¢ robotic gas mixing system at this year\$quot;s Pittsburgh Conference (PITTCON) in Orlando, Florida.

The demonstration will allow viewers to experience the touch-screen interface and easy-to-understand voice commands that Airgas operators use to make specialty gas mixtures at 20 AcuGrav filling stations nationwide.

Developed in-house by Airgas\$quot; automation team, the AcuGrav system features a completely modular data collection unit with state-of-the-art technology, including a real-time embedded control system to handle I/O and time-critical routines. The programming includes 450 subroutines that automate the Airgas standard operating procedures for making gas mixtures with precision and consistency for every batch at every AcuGrav location.

\$quot;Once programmed, AcuGrav takes over making the high-tolerance specialty gas mixtures without the variability of the human element,\$quot; said Rob Shock, director of automation and chief developer of AcuGrav.
