4. If you are using Well Test mode:
a.
Use the Well Data-Densities menu to specify the well to configure.
b.
Assign a name to the well.
c.
Use the Well Data-Densities menu to set the well parameters for the well to be measured. 
See Table 4-1 for definitions of these parameters.
d. Repeat for all wells in the system. 
Note: Micro Motion recommends configuring wells in the order in which they will be tested. For 
example, the first well to be tested should be Well 1; the second well should be Well 2, and so on. If 
you do this, you can use the NEXT function to move to the next well automatically.
5. Use the External Inputs menu shown in Figure 4-1 to enable or disable use of a water cut 
monitor. If 
Water Cut Monitor
 is enabled, additional setup is required. See Section 4.4.
6. Use the External Inputs menu shown in Figure 4-1 to enable or disable gas measurement. If 
Gas Meter
 is enabled, additional setup is required. See Section 4.7.
Table 4-1
Well parameters
Parameter
Default
Description
Well name
None
(Well Test mode only) Enter a name to identify this well.
The name may contain a maximum of 16 characters, including spaces.
Oil density
0.8000 
g/cm
3
The density of oil from this well, at reference pressure and reference temperature. 
Required only if density-based water cut will be used. See Section 2.2.5.
Water density
1.0000 
g/cm
3
The density of water from this well, at reference pressure and reference temperature. 
Required only if density-based water cut will be used. See Section 2.2.5.
Gas reference 
density
0.001205 
g/cm
3
(Used only if gas measurement is implemented) The density of gas from this well at 
reference pressure and reference temperature.
Pressure 
compensated oil 
density
0.0000 
g/cm3/PSI
The factor used to compensate the configured reference density of oil for the effect of 
pressure. See Section 2.3.2.
Reference 
pressure
0.0 PSI
The reference pressure value used to correct line density values to standard density 
values.
Purge time
0 sec
(Well Test mode only) The measurement delay period after a well test has been 
started. Used to allow the separator to empty any contents from the previous test.
Oil deviation
0.5000 
kg/m
3
The maximum acceptable difference between two consecutive density readings 
during a density determination for oil. If the difference is greater than the configured 
oil deviation, the density averaging is restarted. See Section 4.9.2.
Water deviation
0.5000 
kg/m
3
The maximum acceptable difference between two consecutive density readings 
during a density determination for water. If the difference is greater than the 
configured oil deviation, the density averaging is restarted. See Section 4.9.1.
Oil duration ave
30 sec
The sample time, in seconds, for an oil density determination procedure. See 
Section 4.9.2.
Water duration ave
30 sec
The sample time, in seconds, for an in-line water density determination procedure. 
See Section 4.9.1.
