• Sample filter
• Flowmeter
• Heated cell holder assembly
1.3 Typical Applications
Although the OT-2 System is designed in conjunction with the
Elsag Baily Total Flow
TM
System for natural gas production, it also is
capable of monitoring oxygen at the ppm level in a variety of
gases. A few typical applications include:
• Gas gathering and transportation
• Monitoring inert gas blanketing
• Air separation and liquefaction
• Chemical feedstock analysis
• Petrochemical process control
• Heat treating and bright annealing processes
• Quality assurance
• Gas certification
• Welding applications
