3.1 Review
Review the flowmeter configuration parameters set at the factory to ensure accuracy and
compatibility with your particular application of the flowmeter. Once you have activated the
Review function, scroll through the data list to check each variable in the configuration data list.
The last step of start-up and commissioning is to check the flowmeter output to ensure that the
flowmeter is operating properly. Rosemount 8600D digital process variables include: primary
variable, primary variable as a percent of range, analog output, vortex shedding rate, pulse
frequency, mass flow, volumetric flow, velocity flow, totalizer, electronics temperature,
calculated process density, cold junction temperature, and process temperature.
3.2 Process variables
The process variables for the Rosemount 8600D provide the flowmeter output. 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.
3.2.1 Primary Variable (PV)
PV – The measured value of the variable mapped to the primary variable. This can be either
Process Temperature (MTA option only) or Flow. Flow variables are available as mass, volume, or
velocity. When bench commissioning, the flow values for each variable should be zero and the
temperature value should be the ambient temperature.
If the units for the flow or temperature variables are not correct, refer to “View other variables”
on page 30. Use the Process Variable Units function to select the units for your application.
