Fluidwell C571 | Flow & Energy Computer | for natural gas, hydrogen and other gases, ambient -40°C to +55/+70°C
The C571 is a Flow & Energy Computer for natural gas, hydrogen and other gas applications. It measures flow, temperature and pressure and uses AGA8 92DC, SGERG88(91) or table determinations to calculate volume, mass and energy. The linearization enhances accuracy in any flow range. Typical use: For industrial environments, measuring natural gas, hydrogen, carbondioxyde and other gases.
Key features
- Media: Air, nitrogen (N2), oxygen (O2), hydrogen (H2), carbondioxyde (CO2), methane (CH4), natural gas, ideal gas, other gases.
- Displays calculated mass flow,(base) volumetric flow and power at actual conditions.
- Calculates totalized values for (base) volume, mass and energy.
- Determines density, enthalpy , specific heat & compressibility (SGERG88(91) and AGA8 92DC).
- For single stream applications.
- Main screen with custom selectable order of measured and calculated variables.
- Data logging of process parameters and calculated values.
