The Meter has to be disabled to change Meter Type/Product Group or Units
Once the meter type or product group is selected, the software automatically displays the specific parameters
A meter configuration can easily be copied to other meters

20. Pulse Meter Configuration
Pulse Meters - Introduction
A pulse meter requires a high speed counter to transfer pulses to the module
The module will consider each pulse count increment to add a volume amount to the accumulator
The meter uses a direct correlation between number of pulses and volume called K-Factor Example : K-Factor = 100 pulses/cubic feet
Means that 100 pulses is equal to 1 cubic feet

21. Pulse Meter - Configuration
Pulse Meters - Introduction
Pulse Count

22. Pulse Meter - Configuration
Pulse Meters - Introduction
The module uses the following formula to increment the volume:
Gross Vol Incr = [Pulse Count Incr] * MeterFactor
KFactor

23. Pulse Meter - Configuration
Pulse Meters - Introduction
As time goes on the actual measured volume (the "gross volume") will tend to drift from the nominal measured volume (the "indicated volume"). The factor that corrects "indicated" to "gross" is called the "meter factor", and is a number very close to 1.
The Meter Factor usually depends on the Flow Rate. The user may configure up to 5 Meter Factor points to be interpolated, depending on the Flow Rate

Meter Factor Configuration

25. Pulse Meter - Configuration
Pulse Meters - Introduction
Stream Options The calculations described up to this point are those recommended by API and performed by the vast majority of users of linear meters. Some users, however, may prefer to keep the meter factor at exactly and periodically adjust the K-factor with a meter prove -- and then the K-factor may depend on the flow rate.

26. Pulse Meter - Configuration
Pulse Input Rollover
The module considers a rollover when the current pulse count is less than the previous one. In this case, it will use the following formula to re-calculate the pulse input:
Pulse Count = (Current Pulse + Rollover Value) – Previous Pulse
Ex: For a pulse input rollover value of Consider the following sequence of pulses: 32700, 32750, 30, 50 The module would use the following value for pulse input on the next transition: ( ) = 47

27. Pulse Meter - Configuration
Pulse Input Rollover
“Jumps” in the Accumulator value typically happens when the pulse count is set to zero or the user has configured a wrong pulse input rollover value In this situation the module “thinks” that a rollover has occurred and add the remaining pulse amount to rollover

28. Orifice Meter - Configuration
Orifice Meters - Introduction
Requires tube and orifice diameters configuration
The static pressure of the gas stream may be measured either upstream of the meter (before the differential pressure drop), or downstream of the meter (after the pressure drop). Both AGA3 and AGA8 require the upstream static pressure for their calculations,
where: upstream pressure = downstream pressure + differential pressure If the pressure is measured from a downstream tap (typical), this parameter must be checked.

29. Orifice Meter - Configuration
Orifice Meters – Introduction
DP Flow Threshold (kPa)
If at any time the differential pressure input value is less than the DP Flow Threshold parameter, the MVI module will consider the differential pressure as zero (no flow).
DP Alarm Threshold (kPa)
If at any time the differential pressure input value is less than the DP Alarm Threshold parameter, the MVI module will flag a Differential Pressure Low alarm. Note that this alarm is different than the one the module would flag if the differential pressure would be out of range (Input Out of Range: Differential pressure).

30. Gas Product - Configuration
Once gas is selected as the product for the meter, the user may enter the molar concentrations for the elements. The module uses the Detailed Characterization Method that requires all molar concentrations (21 elements).
The molar concentrations can be supplied through: - AFC Manager (static) - Ladder Logic (dynamic w/ Chromatograph device)1 - External Modbus Device (dynamic w/ Chromatograph device) 1

Application Gasoline and jet fuels
(Both selections uses the same input process variables)

33. Liquid Product - Configuration
- The ladder logic must move the “Water %” value for Net value calculation - Density at flowing conditions is required. This value may be either provided directly as a process input, or the AFC may calculate it from the frequency output of a densitometer.
- Default Relative Density parameter = Specific Gravity

34. Liquid Product - Configuration
Densitometer
Obs: The input scaling for density should be configured as 4-20mA The densitometer frequency (Hz) should be moved instead of density

Where T= 20C, P = 47.6 kPag

35. Meter Configuration
If the Input Value is not within the configured range, the module will flag an “Input Out of Range” alarm
In this case, the module will perform flow calculation using the configured DEFAULT value

36. Meter Configuration
The Input Values read by the module may be viewed in the meter monitor window. Using the Calibration feature forces the module to ignore changes in the process input variables.

37. Meter Configuration
Input variables may be entered as: • Floating Point Use Floating Point format in ladder logic Ex: => T = C
• Scaled Integer Use Double Integer format in ladder logic
Ex: => T = 13.42C Ex: => P = 200Kpag Ex: => DP = • 4-20mA Use Double Integer format in ladder logic Ex: T,P and DP => (0%) / (100%)

Obs: The Totalizer is represented as Double Integer data (32 bits)
Obs: The Residue is represented as Floating Point data (32 bits) The Residue is always less than 0

41. Meter Monitor – Scan Count
Using the Meter Monitor window, the user may monitor the backplane scan count and the calculation scan count:
Backplane Scan Count
Calculation Scan Count

42. Meter Monitor - Wallclock
Using the Meter Monitor window, the user may also monitor the WallClock date and time information. The WallClock should be transferred from ladder logic. IMPORTANT: The module will not perform calculation until it receives a valid date and time information from the processor.

43. Meter Monitor - Log
• The user may save the Meter Monitor results as a log file or csv file for Excel. • The user may also print the log file to the local printer.

44. Audit Scan
• An Audit Scan snapshots input values, intermediate calculated values, and output results for each of a short series of calculation scans for a single meter. This allows an auditor to rigorously verify the calculations performed by the AFC on live in-service production meters. • The Audit Scan can be viewed as “snapshots” of the process
Steps: 1- Select the meter number 2 – Select the number of audit scans 3 – Click on “Read” to start audit scans 4 – Click on Details for the calculation results 5- Save the log/csv file or send the results for the local printer

45. Archives Hourly Archives 48 Archives per meter
• The module supports the archiving of data for each meter channel. The archives are periodically generated according to the period duration defined in the Site Configuration.

• In order to configure the archive generation use words Mh00341 (daily) and Mh00421 (hourly). User interface is coming soon! Bit 00 – period select, hourly Bit 01 – archive upon period end Bit 02 – archive upon event Bit 03 – Reserved Bit 04 – reset resettable accumulator 1 upon period end Bit 05 – reset resettable accumulator 2 upon period end Bit 06 – reset resettable accumulator 3 upon period end Bit 07 – reset resettable accumulator 4 upon period end Bit 08 – reset resettable accumulator 1 upon event Bit 09 – reset resettable accumulator 2 upon event Bit 10 – reset resettable accumulator 3 upon event Bit 11 – reset resettable accumulator 4 upon event Bits 12 to 15 – Reserved The default value is set for archive upon period end and archive upon event : Mh00341 = 6 Mh00421 = 7

53. Archives
• Example: Configure Meters 1 through 3 to generate daily archives upon period end (only) and to reset all accumulators upon period end. 1) Using the Modbus Master interface, read word 8341 from the Primary Slave. 2) Replace the default value by a value of 3) Write the new value 4) Repeat steps 1 to 3 for Meters 2 and 3. For these meters the following values should be used: Meter 2 = Meter 3 = 12341

54. Archives
The archives can be accessed through: - AFC Manager Display - AFC Manager Log File - AFC Manager CSV file (for Microsoft Excel) - Local Printer - External Modbus master device

56. Events
An event is any occurrence that may affect the manner in which, or whether, measurement is performed.
Events include:
- any change to a sealable parameter
- power-up (product may have been lost during the power-down period)
- change in PLC operating mode (programming changes may alter measurement)

57. Events
• Events are stored as a circular file • The module stores up to 1999 events
Event 1
Event 2
Event 3
(…)
Event 1999
Event 1998

58. Events What happens when the event buffer is full? Option Set
If all record positions contain events that have not yet been downloaded, the log is full. In this case, the handling of a new event depends on the value of the "Event log unlocked" site option:
What happens when the event buffer is full?
Option Set
Module will overwrite the oldest event with the new one
Option Clear
Module will reject new events (including configuration changes)

59. Events How to use the Event Interface?
1) Click on the Read Button 2) Note the Number of Events to be Downloaded 3) Click on Download 4) Save the Events as a Log File (or CSV) 5) Click on Purge to delete all events

60. Events Understanding the Event Codes
In order to use the available memory in the AFC Manager as efficiently as possible, the events are grouped and coded in a specific format before they are logged.
The event codes are displayed as shown: <Event Type> Group/Subgroup/Item

61. Events Understanding the Event Codes
Examples: Mtr1 9/1/0 = means that Meter 1 Orifice plate measured diameter has changed.
Mtr 2 4/0/1 = means that Meter 2 Input Scaling Temperature (High) has changed.

62. Ladder Logic
The ladder logic allows the processor to request specific tasks to the module. These tasks include: • Set the Wallclock • Write the Process Input Variables • Read the Calculation Results • Transfer the Molar Analysis Data (Gas Only) • Enable or Disable a Meter • Write an Archive • Reset an Accumulator • Read/Write from the Primary or Virtual Slaves • Modbus Pass-Thru
