RealFLO: Input Limit Ranges for Liquid Flow Run Calculations
For RealFLO liquid flow run calculations, API Chapter 11.1 (section 11.1.2.3) and API Chapter 11.2.4 (section 2) specify limits for the inputs; specifically:
  • Base density Ranges

  • Flowing density Input Ranges

  • Temperature Input Ranges

  • Gage Pressure Input Ranges

If any of these inputs are out of range, the following alarm message may appear in RealFLO:





To ensure the inputs are in the proper ranges, refer to the following 4 tables which denote the proper ranges for each product type:

Base Density Ranges




Flowing Density Input Ranges




Temperature Input Ranges




Gage Pressure Input Ranges



The tables above may also be found in the RealFLO Documentation Set in the following location:
