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.

The Primary Variable shows the current measured flow rate. This value determines the analog output from the transmitter.

The PV% Range shows where in the flow range the current flow value is as a percentage of the configured span.

The PV Analog Output displays the mA output of the transmitter corresponding to the measured flow rate.

The Totalizer Setup menu allows for the viewing and configuration of the totalizer parameters.

Totalizer Units

Fast Keys 1, 1, 4, 1

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

Fast Keys 1, 1, 4, 2

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

Fast Keys 1, 1, 4, 3

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.
