SteelMass 640S Insertion Gas Mass Flow Meter

SteelMass 640S Flow Meter by Sierra Instruments
Accurate Metering of Peak, Low Flow and Total Mass Flow Rate

Sierra Instrument's SteelMass 640S delivers precise measurements with heavy-duty industrial gas mass and air flow meter measurement applications. Choose from a wide variety of inline and insertion thermal mass air/gas flow meters for precision SCFM (standard cubic feet per minute), SFPM (surface feet per minute) and SMPS (standard meters per second)  measurement of gas mass flow rate in industrial environments.

The 640S offers accurate monitoring of peak, low flow and total air/gas mass flow rates is a critical part of many industrial process control systems. When 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.
