Figure 4-9 Density determination for oil – Preparing to start
4. The display now shows the current values for oil density, oil temperature, volume, and
flowrate (see Figure 4-9), plus the configured Oil Deviation and Oil Duration Ave values.
Monitor the density and temperature values, watching for the density and temperature readings
to stabilize.
Note: The Oil Deviation and Oil Duration Ave values shown here are read-only. If you need to change
them, you must reconfigure the well data. See Section 4.3.
5. (Optional) Press
RESET to reset the volume total to 0. This enables you to monitor the amount
of fluid that remains in the separator (if the separator volume is known).
6. When the density reading has stabilized at a level that indicates that live oil is flowing through
the sensor, press
START. The NOC application will now average the density and temperature
of the process fluid until a good sample is achieved.
A “good sample” means that, for the configured Oil Duration Ave, no two consecutive density
readings differed by more than the configured Oil Deviation limit. If the oil deviation limit is
exceeded, averaging is restarted.
Note: If the averaging procedure does not end automatically, you may need to verify your process
fluid or increase the Oil Deviation value.
During this period, the screen shown in Figure 4-10 is displayed. You can press
STOP to stop
the averaging. You will be returned to the previous screen.
