Notes
The Rosemount 8600D measures the volumetric flow under operating conditions (i.e. the actual
volume at the operating pressure and temperature–acfm or acmh), as shown above. However,
gas volumes are strongly dependent on pressure and temperature. Therefore, gas quantities are
typically stated in standard or normal conditions (e.g. SCFM or NCMH). (Standard conditions are
typically 59 °F and 14.7 psia. Normal conditions are typically 0 °C and 1 bar abs.)
The flow rate limits in standard conditions are found using the equations below:
Standard Flow Rate = Actual Flow Rate X Density Ratio
Density Ratio = Density at Actual (Operating) Conditions / Density at Standard Conditions
