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:
