Analog Output – The analog output variable provides the analog value for the
flow rate. The analog output refers to the industry standard output in the 4–20
mA range. The analog output and 4-20 mA loop can be verified using the
Analog Feedback diagnostic capability internal to the transmitter (See “8714i
Meter Verification” on page C-8).
Totalizer Setup – Provides a reading of the total flow of the flowmeter since
the totalizer was last reset. The totalizer value should be zero during
commissioning on the bench, and the units should reflect the volume units of
the flow rate. If the totalizer value is not zero, it may need to be reset. This
function also allows for configuration of the totalizer parameters.
Pulse Output – The pulse output variable provides the pulse value for the flow
rate.
PV - Primary Variable The Primary Variable shows the current measured flow rate. This value
determines the analog output from the transmitter.
PV -% Range The PV% Range shows where in the flow range the current flow value is as a
percentage of the configured span.
PV - Analog Output The PV Analog Output displays the mA output of the transmitter
corresponding to the measured flow rate.
Totalizer Setup The Totalizer Setup menu allows for the viewing and configuration of the
totalizer parameters.
Totalizer Units
Totalizer units allow for the configuration of the units that the totalized value
will be displayed as. These units are independent of the flow units.
Measured Gross Total
Measured gross total provides the output reading of the totalizer. This value is
the amount of process fluid that has passed through the flowmeter since the
totalizer was last reset.
NOTE
To reset the measured gross total value, the line size must be changed.
Measured Net Total
Measured net total provides the output reading of the totalizer. This value is
the amount of process fluid that has passed through the flowmeter since the
totalizer was last reset. When reverse flow is enabled, the net total represents
the difference between the total flow in the forward direction less the total flow
in the reverse direction.
