Viewing Continuous mode measurement data
To view basic data from Continuous mode measurement, use the Quick View menu shown in
Figure 5-3. Process variables available from the Quick View menu are listed in Table 5-6.
Figure 5-3. Process variables available from the Quick View menu are listed in Table 5-6.
Note: You can also read Continuous mode measurement data via Modbus or report actual and
average process variables by assigning them to a milliamp or frequency output.

To view more detailed data, use the View Production Measurement menu shown in Figure 5-3. This
screen provides:
screen provides:
•
Production data for several other process variables, as listed in Table 5-7
•
TMR data, as listed in Table 5-8

Definition
Average net oil rate
Average net oil flow rate, calculated from the beginning of Continuous mode measurement or
from the last reset. May or may not include oil carry-over, depending on TMR configuration.

Net oil total
Total net oil, by volume, calculated from the beginning of Continuous mode measurement or
from the last reset. May or may not include oil carry-over, depending on TMR configuration.

Average water cut
Average water cut value, calculated from the beginning of Continuous mode measurement or
from the last reset. May be either density-based or from the water cut monitor, depending on
water cut configuration.
