1.8.4.3 Activating Mass Flow
Use this option to calculate mass flow from a static fluid density. Complete the following steps to enter the static
density of the fluid:
IMPORTANT: The Model XGM868i can use a static density from either a single value of density (Rho), or from the live
or fixed temperature and pressure inputs, as programmed in the I/O menu, along with a single entered
value of Molecular Weight (MW). This is done by setting the Mass flow calculation prompt to Yes and
following the prompts below to calculate mass flow.
1. In the Keypad Program , scroll to PROG and press [Enter].
2. In the PROG menu, scroll to CH1 or CH2 and press [Enter].
3.
In the Channel PROGRAM menu, scroll to Setup and press [Enter].
4.
Scroll to ADVAN. Press [Enter].
5.
Scroll to MASS, and press [Enter].
6. Scroll to Yes to activate, or to No to deactivate Static Density, and press [Enter].
Note: If you scroll to No, go to Procedure Options below.
7. Scroll to the Density Type (fluid density (Rho) or molecular weight (Mw)) and press [Enter].
8.
Do one of the following:
• If you selected Rho - proceed to Step 9.
• If you selected Mw - proceed to Step 11.
9. Scroll to the type of volumetric units (standard - StVOL or actual-AcVOL) for the measurement data display and
press [Enter].
10. Enter the Fluid Density (0.00001 to 0.100 lb/ft
below.
11. Enter the Molecular Weight and press [Enter].
Procedure Options
After completing the steps on the previous page, the XGM868i returns to the Advanced Features window. Do one of the
following:
• To continue programming, refer to Appendix A, Menu Maps , to navigate to the desired menu.
• To leave the Keypad Program , press [Escape] five times.
