Process variables

Process variables

are available through the Field Communicator or AMS software suite.

These variables display flow in several ways that reflect your needs and the configuration of
your flowmeter. When commissioning a flowmeter, review each process variable, its
function and output, and take corrective action if necessary before using the flowmeter in a
process application.

Primary variable

(PV) - The actual measured flow rate of the process fluid. Use the

flow units

function to select the units for your application.

Percent of range

- The process variable as a percentage of the analog output range, provides

an indication where the current flow of the meter is within the configured range of the
flowmeter. For example, the analog output range may be defined as 0 gal/min to 20
gal/min. If the measured flow is 10 gal/min, the percent of range is 50 percent.

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

“4-20 mA loop verification” on page 123

).

Pulse output

- The

pulse output

variable provides the pulse value in terms of a frequency for

the flow rate.

4.5.1

PV - Primary variable

The

primary variable

shows the current measured flow rate. This value determines the

analog output from the transmitter.

4.5.2

PV - Percent of range

The

PV% range

shows where in the flow range the current flow value is as a percentage of the

configured span.
