- Insertion, totalizing air/gas mass flow meter
- Eliminate drift with patented DrySense™ sensor
- Increase flexibility with low pressure drop, high turndown
- Validate in the field for easy in-situ calibration
- Backed by lifetime sensor warranty
- The SteelMass 640S provides more accurate monitoring of peak, low flow and total air/gas mass flow rates, a critical part of many industrial process control systems. If you need a portable analog or digital air flow meter that easily inserts into industrial ducts and pipes up to 72 inches (2 m), choose SteelMass® 640S.
