- OFS - Laminar Flow Element differential pressure flowmeters are good for clean, dry, non-corrosive, non-condensing gases. Corrected for temperature and pressure, they have a mass flow output.
 - LCD display of flow rate or total, pressure and temperature.
 - Current, voltage or pulse out
 - Intrinsically safe option - CSA and CE
 - Rapid response
 - All common non-aggressive gases such is air, nitrogen, argon, helium, hydrogen, natural gas and carbon dioxide
 - Type 4 construction (weather proof)
 - Built-in alarm switches
 - NIST traceable
 - Can be installed in any orientation
