Gas-SelectX® is a revolutionary new feature that enables the user to have a meter that can accurately measure different gases. The user can select from the list of gases below or mix from the list to create a custom gas mixture specifically for their own application! All FT4X flowmeters are pre-programmed for:
| Menu for clean gases | Menu for mixed gases | Menu for gases for Oil/Gas |
| - Air | - Air | – Methane (C1) |
| - Argon | - Argon | - Etan (C2) |
| - Butane | - Butane | - Propane (C3) |
| – Carbon dioxide | – Carbon dioxide | – Isobutane (C4) |
| - Helium | - Etan | – Normal butane (C4) |
| - Wet | - Helium | – Pentane (C5) |
| - Methane | - Wet | – Hexane (C6) |
| – Natural gas* | - Methane | – Heptane (C7) |
| - Nitrogen | - Nitrogen | – Octane (C8) |
| - Acid | - Acid | – Nonane+ (C9+) |
| - Propane | - Propane | – Carbon dioxide |
| - Nitrogen |
Any combination of gases in the Mixed Gas and Oil & Gas Menus can be mixed in 0.1% increments to create a custom gas mix. The Gas-SelectX® feature can be accessed through the front panel of the meter or by using the free FT4X View™ software tool.
*Natural gas refers to pipeline-quality dry natural gas. Fox Thermal uses the NAESB standard as the default composition for natural gas in the Pure Gas menu of Gas-SelectX®. Naturally occurring gas – from oil fields commonly referred to as Associated Gas – may have a different percentage of gas constituents in its composition. Use the Mixed Gas or Oil & Gas Menu in Gas-SelectX® to program the correct percentages of the natural gas or contact Kompauto Nordic for further information.
