2.3.6 Mass flow test calculation
The mass flow test calculation method allows the user to verify the flow configuration of
the Rosemount 3051SMV by entering expected values for the differential pressure,
absolute pressure, and process temperature variables. Test calculation units are always in
inH2O at 68 °F for differential pressure, psi for static pressure and °F for temperature.
To perform a test calculation, select Actions > Methods > Methods > Mass Flow Test
Calculation and follow the on-screen prompts.
Note
The device must be in Automatic Mode in order to successfully perform a mass flow test
calculation. If the resource block is not in automatic mode, the test calculation method
will still run, but the method will report the last live values, rather than the test calculation
outputs.
2.4 Variable configuration
2.4.1 Units configuration
Units for transmitter variables are configured in the XD Scale parameter in each AI Block.
Each AI Block is connected to a transmitter variable according to the Channel parameter in
the AI Block. When the units in an AI Block are changed, the units of the connected
channel variable will be changed in the Sensor Transducer Block or the Mass Flow
Transducer Block accordingly. If multiple AI Blocks are set to the same channel, the XD
Scale units must be manually synchronized to resolve configuration errors.
2.4.2
Mass flow
The following configuration items are found in the Mass Flow Transducer Block.
Note
These configuration items only apply to the Fully Compensated Mass Flow transmitter.
Reference Manual 17
Configuration Reference Manual
January 2019 00809-0100-4853
Low flow cutoff
If the measured Differential Pressure value is less than the Low Flow Cutoff value, the
transmitter will calculate the Flow Rate value as zero.
The unit for this value is always inH2O at 68 °F.
Process temperature mode
The mass flow calculation can use a live process temperature reading or a fixed value
based on the selected Process Temperature Mode. To configure it, select Actions >
Methods > Methods > Mass Flow PT Mode Setup and follow the on-screen prompts.
Mode Description
Normal The transmitter will only use the actual measured process temperature value. If the
temperature sensor fails, the Flow output will go to Bad status.
Backup The transmitter will use the actual measured Process Temperature value. If the
temperature sensor fails, the transmitter will use the value shown in Fixed PT.
Fixed The transmitter will always use the temperature value shown in Fixed PT.
2.4.3
2.4.4
Note
The unit for the Fixed Process Temperature value always matches the Process
Temperature primary value unit. To change this unit setting, see Units configuration.
Differential pressure
The following configuration items are found in the Sensor Transducer Block.
Damping
The damping setting changes the response time of the transmitter; higher values can
smooth variations in output readings caused by rapid input changes. Determine the
appropriate damping setting based on the necessary response time, signal stability, and
other requirements.
The setting for Differential Pressure Damping also affects the Mass Flow.
Static pressure
The following configuration items are found in the Sensor Transducer Block.
Damping
The damping setting changes the response time of the transmitter; higher values can
smooth variations in output readings caused by rapid input changes. Determine the
appropriate damping setting based on the necessary response time, signal stability, and
other requirements.
The setting for static pressure damping affects both absolute and gage pressure
measurements.
18 Reference Manual
Reference Manual Configuration
00809-0100-4853 January 2019
Atmospheric offset
Both absolute and gage pressure are available as variables. The type of transmitter ordered
will determine which variable is measured. The transmitter will calculate either absolute or
gage pressure based on the user-defined atmospheric offset.
2.4.5 Process temperature
The following configuration items are found in the Sensor Transducer Block.
Damping
The damping setting changes the response time of the transmitter; higher values can
smooth variations in output readings caused by rapid input changes. Determine the
appropriate damping setting based on the necessary response time, signal stability, and
other requirements.
Callendar-Van Dusen Coefficients
The Rosemount 3051SMV accepts Callendar-Van Dusen constants from a calibrated RTD
schedule and generates a special custom curve to match that specific sensor Resistance
vs. Temperature performance. Matching the specific sensor curve with the transmitter
configuration enhances the temperature measurement accuracy. Under Actions > Methods
> Methods, the Callendar-Van Dusen constants R0, A, B, and C can be viewed. If the
Callendar-Van Dusen constants are known for the user’s specific Pt 100 RTD sensor, the
constants R0, A, B, and C may be edited by selecting the Callendar-Van Dusen Setup
method and following the on-screen prompts. The user may also view the α, β, and δ
coefficients by selecting the View Alpha, Beta, Delta button. The constants R0, α, β, and δ
may be edited by selecting the Callendar-Van Dusen Setup and following the on-screen
prompts. To reset the transmitter to the IEC 751 Defaults, select the Reset to IEC 751
Defaults method.
User-defined process temperature sensor limits
Process temperature sensor limits can be changed to allow early detection of RTD failures.
When the limits are exceeded, the transmitter will display a Process Temperature Out of
Limits alert in the transmitter status, set the PT measurement status to uncertain, and will
stop using the measured temperature value in the flow calculation. See Mass flow on page
10 for more information on configuring the process temperature mode for mass flow.
Enable/disable process temperature
Using the PT Measurement parameter, the Process Temperature measurement can be
disabled to prevent undesired diagnostic alarms and local display screens. This feature
may be useful if the Process Temperature option was ordered but will not be used or if the
RTD in use has failed and a replacement is not readily available.
When the Process Temperature measurement is disabled, the Process Temperature
measurement status will be “bad”. If using mass flow calculations, set the Mass Flow’s
Process Temperature Mode to Fixed to allow calculations to continue. Once an RTD is
available and wired, set the PT Measurement to Enabled and the Process Temperature
Mode to Normal to allow the live reading to be used for mass flow calculations.
