The GFM-1145 is a precision gas mass flowmeter designed to measure high-volume nitrogen or clean air flows up to 1000 LPM. Optimized for utility gas monitoring in cooling systems or environmental enclosures within data centers, it offers stable, reliable performance and ease of installation via compression fittings.

• Flow range: 0–1000 LPM
• 3/4" compression connection
• Standardized for nitrogen at 70°F and 760 mm Hg
• Aluminum body
• Accurate mass flow readings for dry gas applications
