To wire the flow computer, get familiar with the drawings provided in the software’s Wiring menu. Use
the arrow left and right keys to move to and select Wiring, then press ENTER.
Back terminal wiring:
The back terminal wiring indicates the overall positions of the terminal plugs and their functions. Though
the back panel’s jumpers are also shown, refer to the next drawing, “Back Panel Jumpers”, for information
on their settings and functions.
The Smart Flow Computer receives its power via the two topmost pins on Terminal P1, on the left of the
terminal board. Also on Terminal P1 are, from top to bottom, inputs from the two turbines and the RS-485
serial connection.
To the right (P4), from top to bottom, is status input 1, density frequency input, and switch output 1 and 2.
Terminal P3, at the lower bottom, handles analog inputs and outputs. These are, in order from right to left,
analog inputs 1-4 and analog outputs 1 and 2.
Terminal P5, top middle, is the RTD terminal block, "100 platinum RTD input".
INPUT/OUTPUT: Assignment, Ranging, Wiring, and Calibration
Input/Output Assignment
We will now configure your Smart Flow Computer’s inputs and outputs. The flow computer allows the
user to configure the inputs and outputs. i.e. Analog #1 is pressure for Meter #1. Unassigned inputs are not
used by the flow computer.
How to assign a transmitter to an I/O point:
Before beginning the procedure of assigning inputs and outputs, it is advisable to set up the meter (Meter
| Set Up). This is because certain parameters on the Transducer Input Assignment page
change (or may not appear, etc.) based on Meter | Set Up.
1 Use your arrow keys to scroll to menu item I/O (between Meter and Report). Its first
entry is Transducer Input Assignment. Press <ENTER>.
2. Use the down/up arrow key to scroll through this menu. The first four parameters are used to
set the number of decimals you would like to see in your live inputs (these numbers do not
affect the precision of your calculated data). Spare inputs are inputs that the flow computer
will read and display in the diagnostic data but are not used in the calculations. Spare inputs
high and low limit alarms are documented in the historical alarm report.
3. After the parameters used for setting the number of decimals come a series of parameters
ending with the words Assignment (1-n). Assignments 1-4 are analog
inputs attached to terminal P3 of the back panel. These
inputs accept 4-20mA or 1-5 volts input and are suitable for temperature, pressure,
density, BS&W, or spare inputs. Assignments 5 and 6 are strictly RTD (temperature) inputs
only for the meter, prover, densitometer or spare; temperatures are inputted via terminal P5
on the back panel. Assignment 7 indicates a density frequency input; it is assigned
automatically once you choose live density frequency input in the setup menu at density type
selection (and it can only be assigned via Meter | Set Up | Density #n, where n = 1 to
4). Assignment 10 (module 1) and assignment 11 (module 2) are used for Rosemount multivariable module only. DP, pressure, and temperature for the meter can be assigned.
Ranging the Transmitter Inputs:
1. Enter the range values: after assigning the inputs scroll down the transducer inputs
assignment menu to scale the 4-20mA. Enter the value at …@4mA and …@20mA. Enter both
values similar to the way the transmitter is ranged. 1-5 volts is equivalent to 4-20mA. Enter
the 1 volt value at the 4mA, and 5 volt value at 20mA.
2. Enter the high and low limits: high limits and low limits are simply the alarm points in
which you would like the flow computer to flag as an alarm condition. Enter these values
with respect to the upper and lower range conditions. Try to avoid creating alarm log when
conditions are normal. For example: If the line condition for the pressure is between 0 to 500
PSIG. then you should program less than zero for low pressure alarm, and 500 or more for
high pressure alarm. High and low limits are also used in the scale for the Modbus variables.
3. Set up the fail code:Maintenance and Failure Code values tell the flow computer
to use a default value in the event the transmitter fails. The default value is stored in
Maintenance. There are three outcomes: the transmitter value is always used, no matter
what (Failure Code = 0); the Maintenance value is always used, no matter what
(Failure Code = 1); and the Maintenancevalue is used only when the transmitter’s
value indicates that the transmitter has temporarily failed (Failure Code = 2).
RTD inputs will skip 4-20mA assignments because RTD is a raw signal of 50 (ohms) to 156. Readings
beyond that range require a 4-20mA signal to the flow computer.
Density coefficients for raw frequency inputs are programmed in this menu. The menu will only show
parameters relevant to the live density selected (i.e., Solartron or UGC, etc.).
NOTE: Solartron density input requires values in US units, i.e. PSI, and
F. Request a calibration sheet in US units from the densitometer
Wiring to the flow computer is very straightforward and simple. But still it is very important to get familiar
with the wiring diagram.
Wiring the analog inputs:
Use your arrow keys to move the cursor to the menu item Wiring and then use up/down arrow keys to
select Analog Wiring. Press <ENTER>. Typical wiring for analog inputs 1 and 2 are shown in the
drawing. Analog inputs 3 and 4 are to the left of analog 1 and 2. Note that the analog input has only one
common return, which is the -ve signal of power supply powering the transmitters.
When wiring 1-5 volts, make sure to calibrate the flow computer for the 1-5 volt signal because the flow
computer calibration defaults for the 4-20mA, which is different from the 1-5 volts. JP5 must be cut for 15 volt inputs. The jumpers for analog 1-4 are in order from right to left. It is possible to cut the first two
jumpers for analog 1 & 2 in for 1-5 volts signal and have analog in 3 & 4 as 4-20mA signal. Signal line
impedance provided by our flow computer is less than 250. Therefore, when using a smart transmitter
that requires a minimum of 250 resistance in the loop, an additional resistor at the flow computer end
needs to be installed in series with the 4-20mA loop in order to allow the hand held communicator to talk to
the transmitter.
NOTE: The 4-20mA or 1-5 volt DOES NOT source power to the transmitters. You can use
the DC power feeding the flow computer to power the 4-20mA loop IF that power
supply is FILTERED.
When ‘Flow Computer’ is configured as 4 analog inputs and 2 RTD inputs, go to the wiring menu where it
says RTD and press <ENTER>. The flow computer shows wiring to RTD 1 and RTD 2. 100 platinum
can be used; a temperature range of -43F to +300F can be measured. RTD 1 is to the right where P5
designation is. In the figure below notice that each side of the RTD requires two wire connections. When
using less than 4 wires a jumper must be used to make up for the missing lead. Internal excitation current
source generated is approximately 7mA. .
The analog outputs are located on the left side of P3 connector. Go to the wiring diagram and scroll down
to Analog Output and press <ENTER>. Wiring diagram shows typical Analog output wiring. Notice
that analog output will regulate 4-20mA current loop but DOES NOT source the power for it. External
power is required.
ASS IGNING/RANGING THE 4-20MAAN ALOG OUT PUTS :
Go to the I/O assignment main menu and scroll to Analog Output Assignment. Press
<ENTER>. A selection menu is prompted. Select the analog output number and then enter what the 4mA
output will indicate and the 20mA. Make sure that the 20mA assignment value exceeds the upper range
limit of what you assigned the Analog output for, otherwise the analog output will not update beyond
20mA.
Scroll to Turbine under Wiring and press <ENTER>. Two drawings above each other will show
typical wiring for turbine meter 1 and turbine meter 2. When dual pick ups from the same turbine are
connected, use the inputs for turbine 1 for pickup 1 and turbine 2 for the second pickup coil. When
connecting sine wave directly from the pickup coil make sure the distance from the pickup coil to the flow
computer is very short--less than 50 feet with shielded cable. In the event there is presence of noise, the
distance must be shortened. When connecting sine wave signal, the R11 jumper for meter 1 must be
installed and R3 jumper for meter 2 must be installed. (JP3 and JP2 must be off when using sine wave).
On the other hand, when using square wave, the square wave signal can be sinusoidal but has to be above 5
volts peak to peak with less than 0.4 volts offset in order for the flow computer to read it. R11 and R3 must
be off and JP3 on for meter 1; JP2 must be on for meter 2.
Note: When connecting square wave input, the JP3 and JP2 connect the turbine return to the
flow computer power return. Therefore, signal polarity is very important. Reverse polarity
could result in some damage or power loss. When sine wave is used the signal polarity is
usually of no significance.
The turbine input is immediately under the power input on terminal P1. The third pin down from the top is
Turbine/PD "minus", and below it is Turbine plus. The second pulse input for Turbine/PD meter 2 or the
second pickup coil is below turbine one input on P1. The fifth pin down from the top is turbine 2 "minus"
signal and below it is Turbine/PD 2 plus signal.
Turbine input wiring for passive (dry contact) pulse generators
Some mass flow meters have pulse outputs that do not provide power but instead require
external power, they are referred to as passive outputs, dry outputs, open collector, etc. (For
example the Krohne UFM 3030 Mass meter).
In these cases the wiring should be as shown on the below diagram. The pull up resistor can be
adjusted to limit the current sink by the Mass meter. For Turbine Input 1 JP3 must be ON and
R11 OFF and if using Turbine Input 2 then JP2 must be ON and R3 OFF.
When using a live densitometer input with frequency signal, the signal can be brought into the Smart Flow
Computer in its raw form. The Smart Flow Computer accepts a sine wave or square with or without DC
offset. Example for density wiring can be seen in the wiring diagram. Use the arrow keys to get to
Wiring | Density and press ENTER. Find two drawings, one with barrier and the other without.
Barriers are used for area classification. Notice that the RTD wiring is also drawn to show how to hook the
density RTD signal.
Note: When wiring the density input polarity is of significance and
reverse polarity could result in some damage or power loss. The
density signal is on connector P4, the third and fourth pin down
from the top. The third pin down is density plus, the fourth down is
density minus. When Density input is 4-20mA it should be
connected as a regular 4-20mA signal to the analog input and not
the density frequency input.
The RS-232 is not located on the terminal board. The RS-232 is a green 5 pin terminal block with screw
type connector located on the display side of the enclosure. Scroll to Wiring | New RS-232 and press
ENTER. Termination jumpers for the RS-232 are located at the top corner of the board on the same side of
the RS-232 connector. The two jumpers at the top are for terminating the transmit line and below it is the
receive line.
The RS-232 port can be used for printing reports, Modbus communication, or interfacing to the
configuration program. If the port is configured as printer port in the flow computer communication setup,
then reports get printed (i.e. interval and daily reports).
Note: Twisted shielded cable is required.
WARNING: When the RS-232 terminal is used with a modem, external
RS-485 wiring is shown in the wiring diagram under RS-485. The RS-485 termination jumper is JP4
located on the back terminal. The maximum distance when 18 gauge wire is used would be 4000 feet.
Note: Twisted shielded cable is required.
WARNING: When the RS-485 terminal is used, external transient
protection and optical isolation is required, especially for long
distance wiring.
There is one status input standard and an optional three more on the back of the CPU board. The standard
status input is shown in the wiring diagram under Status Input. It has 4 volts of noise hysteresis,
with a trigger point of 5 volts and an off point of 1 Volt. Status inputs 2, 3, and 4 require the I/O expansion
connector and its wires be installed; refer to wiring drawing IO-Exp. Connection numbers 6, 7, and 8 are
the status in (positive) for inputs 2, 3, and 4, respectively, and 11 is the return for all three inputs.
Scroll to Switch output under Wiring and press <ENTER>. The wiring diagram shows switch 1
and 2 and the return. Please note that switches 3, 4, and 5 cannot be used for pulse output; switches 1 and 2
can be used for pulse or switch output. See also I/O Expansion. Notice that the switch outputs are
transistor type outputs (open collector type with maximum DC rating of 350 mA continuous at 24 VDC)
and require external power.

I/O Expansion:
The I/O expansion is 16-pin connector next to the RS-232 terminal. Eleven pins of the 16-pin connector
are utilized. When the flow computer is ordered with the I/O expansion feature, the wires and the plug are
provided with the flow computer. There will be 11 wires with the wire number tag at the outer end of the
wire. The tag will indicate the wire number. The following is the sequence for the wires. On the top right
edge of the connector towards the top outer side of the CPU board is pin 1, across from it is pin 9.
Calibrations are performed under I/O | Calibration. Use the arrow keys to scroll to
Calibration and press <ENTER>. After you press <ENTER> the screen should show
COMMUNICATION STATUS : OK.
OFF SET CALIBRATION:
For simple offset type calibration simply induce the signal into the analog input and make sure the flow
computer is reading it. After you verify that the flow computer recognized the analog input press <F8>.
The screen will freeze. Scroll down to the analog input you are calibrating and enter the correct mA
reading. Then press <ENTER> followed by pressing F3 function key to download. The screen will stay in
the freeze mode. To bring the live readings press <F2> key , and then the flow computer will display the
new calibrated readings. The offset type calibration is mainly used when a small offset adjustment needs to
be changed in the full-scale reading. The offset will apply to the zero and span.
FULL CALIBRATION METHOD:
To perform full calibration be prepared to induce zero and span type signal.
1. Induce the low end signal i.e. 4mA in the analog input.
2. Press <F8> and scroll down to the reading then press <ALT><R> (alternate key and the letter
R simultaneously). Then immediately enter the analog input value i.e. 4mA. Follow that by
< ENTER> and then press <F3> function key to download data.
3. Now be ready to enter the full-scale value. Simply induce the analog signal and then enter
the value i.e. 20mA, and then download by pressing <ENTER>, then press <F3> function key.
4. Induce live values to verify the calibration.
DEF AULT CALIBRATION
Simply press <F8> and scroll to the analog Input and press <ALT><R> followed by <F3 function key.
RTD Calibration is a 2-step process. The first step is a one time procedure to verify transducer
linearity and is done at the time the meter is being setup. The second step is the routine calibration
sequence.
Step 1 – Linearity Verification
1. Use a Decade box with 0-150 °F settings.
2. Connect RTD cable to this resistive element for verification of linearity. Verify low and high points.
It must be within ½ degree.
3. Connect the actual RTD element and compare with a certified thermometer.
4. If not within ½ degree do a Full Calibration (See Full Calibration below). If problem persists verify
other elements such as RTD Probe, connections, shield, conductivity of connectors, etc.
The purpose of the above procedure is to verify zero and span and make sure that the two points
fall within the expected tolerance.
Step 2 – Routine Calibration
Once Linearity has been verified through Step 1, the routine calibration procedure is reduced to
simply connecting the actual RTD and doing an offset point calibration (see offset calibration
below).
Calibration after that will be simple verification for the stability of the transmitter. If it drifts abnormally
then you need to verify the other parts involved.
RESET TO DEFAULT CALIBRATION
To go back to the default calibration simply press <F8> and scroll to the RTD input, and press
<ALT> <R> key followed by <F3> function key.
OFFSET CALIBRATION:
For offset calibration simply go to I/O | Calibration and press <ENTER>. Once the flow
computer shows communication status OK press <F8> function key and scroll to RTD. Induce a
live value and wait for 10 seconds for the reading to stabilize. Then enter the live value followed
by <F3> function key to download the direct reading. The value entered must be in ohms only.
FULL SCALE CALIBRATION:
1. Prepare low range resistive input (i.e., 80) and High range resistive input (i.e., 120). Go to
the calibration menu and press <F8> function key. Scroll to the RTD input you are calibrating
and press <ALT> <R> (key <ALT> and the letter R at the same time). Induce the low end
(80) resistive signal and then wait 10 seconds and enter 80 followed by pressing the <F3>
function key.
2. Induce higher range signal (120) and wait 10 seconds, then enter the number 120 ohm and
press the <F3> key.
3. Now verify the live reading against the flow computer reading.
To calibrate the analog output against the end device follow the following steps:
1. Go to the calibration menu and press <F8>. Scroll down to analog output and press <ENTER>
and then <ALT><R>. This will cause the flow computer to output the minimum possible
signal 3.25 mA. Enter the live output value reading in the end device i.e. 3.25 mA and press
<F3> function key. Now the flow computer will output full scale 21.75 mA. Enter the live
output i.e. 21.75 then press the <F3> key.
2. Now verify the output against the calibration device.
Multi-Variable Transmitters (Model 205)- DP and Pressure
OFF SET CALIBRATION
1. Induce live value for temperature, pressure, or DP.
2. Go to Calibration - Multi-Variable menu.
3. Press <F8>, point to the value being calibrated, enter the correct value followed by
<ENTER>, and then press <F3> to download data.
4. Now read induce live values to verify the calibration.
FULL SCALE CALIBRATION
1. Press <F8>. Scroll to the parameter to be calibrated, and then press <ALT><R>
2. Induce the low range signal, then press <ENTER> followed by <F3>.
3. Induce the high range signal, then press <ENTER> followed by <F3>.
4. Now verify the live reading against the flow computer reading.
TO USE DEFAULT CALIBRATION
1. Select Multivariable DP or pressure
2. Select Reset calibration method
3. Now verify the live reading against the flow computer reading
Calibrations are performed under I/O | Calibration. Use the arrow keys to scroll to
Calibration-Multi-Variable and press < ENTER>. After you press < ENTER> the screen
should show COMMUNICATION STATUS : OK.
RTD Calibration is a 2-step process. The first step is a one time procedure to verify transducer
linearity and is done at the time the meter is being setup. The second step is the routine calibration
sequence.
Step 1 – Linearity Verification
1. Use a Decade box with 0-150 °F settings.
2. Connect RTD cable to this resistive element for verification of linearity. Verify low and high points.
It must be within ½ degree.
3. Connect the actual RTD element and compare with a certified thermometer.
4. If not within ½ degree do a Full Calibration (See Full Calibration below). If problem persists verify
other elements such as RTD Probe, connections, shield, conductivity of connectors, etc.
The purpose of the above procedure is to verify zero and span and make sure that the two points
fall within the expected tolerance.
Step 2 – Routine Calibration
Once Linearity has been verified through Step 1, the routine calibration procedure is reduced to
simply connecting the actual RTD and doing an offset point calibration (see offset calibration
below).
Calibration after that will be simple verification for the stability of the transmitter. If it drifts abnormally
then you need to verify the other parts involved.
RESET TO DEFAULT CALIBRATION
To go back to the default calibration simply press <F8> and scroll to the RTD input, and press
<ALT> <R> key followed by <F3> function key.
OFFSET CALIBRATION:
For offset calibration simply go to I/O | Calibration and press <ENTER>. Once the flow
computer shows communication status OK press <F8> function key and scroll to RTD. Induce a
live value and wait for 10 seconds for the reading to stabilize. Then enter the live value followed
by <F3> function key to download the direct reading. The value entered must be in degrees only.
FULL SCALE CALIBRATION:
1. Prepare low range resistive input (i.e., 80) and High range resistive input (i.e., 120). Go to
the calibration menu and press <F8> function key. Scroll to the RTD input you are calibrating
and press <ALT> <R> (key <ALT> and the letter R at the same time). Induce the low end
(80) resistive signal and then wait 10 seconds and enter the equivalent temperature in
degrees followed by pressing the <F3> function key.
2. Induce Higher range signal (120) and wait 10 seconds, then enter the temperature degrees
equivalent to 120 followed by pressing the <F3> function key.
3. Now verify the live reading against the flow computer reading.
Use the diagnostic menu. Scroll down by using the arrow keys to Diag | Diagnostic Data and
press <ENTER>. A live input and output is displayed. On the top of the screen pulse inputs and density
frequency input are shown. Compare the live value against the displayed value on the screen. Failure to
read turbine input could be a result of a bad preamplifier or the jumper selection for sine and square wave
input are not in the right position. Refer to wiring diagram Wiring | Turbine for proper turbine
input wiring. Density input can be sine or square wave with or without DC offset. Minimum accepted
signal has to be greater than 1.2 volt peak to peak. Status input is shown below the frequency input to the
left of the screen. When the status input is on, the live diagnostic data will show ON. Minimum voltage to
activate the status is 7 volts with negative threshold of 2 volts. Switch outputs are to the right of the status
inputs. Press <F8> in the diagnostic menu to manually activate the switch outputs to the on and off
position. After the screen freeze the cursor will point to switch output one. Use the space bar to toggle the
switch on/off and the <ENTER> key to advance to the next switch. Press <ESC>to exit diagnostic screen.
The switch outputs are open collector and require external voltage.
When interfacing with Small Volume Provers (SVP), Dynamic uses Dual chronometry as the pulse
interpolation method which is required for provers providing less then 10,000 unaltered pulses.
Pulse interpolation is a pulse counting technique used to calculate the total number of meter pulses between
two detectors, including fractional pulses. A conventional pipe prover requires a minimum of 10,000
unaltered pulses to ensure an accurate test. This minimum is based upon the assumption there is a potential
error of 1 pulse each time a detector is passed, which equates to a 2-pulse error per run. The value of 2 pulses
per 10,000 equates to a potential 0.02 % error. SVPs require less than 10,000 pulses, which would equate to
a potential error greater than 0.02 %.
To enhance the meter's pulse output, Small Volume Provers use pulse interpolation for fractional meter pulse
counting. To interpolate fractional meter pulses or to mathematically interpolate partial pulses, Dynamic uses
the double chronometry method for this purpose since it is the method most widely used.
Double Chronometry:
Double chronometry pulse interpolation increments time precisely every millisecond. A high frequency
master oscillator operates two time counters referred to as Time A and Time B. Time A starts when the first
detector switch is tripped, and Time B starts with the leading edge of the first flow meter pulse after Time A
has started. Time A is stopped when the final detector is tripped and Time B is stopped with the leading edge
of the first flow meter pulse after Time A has stopped (see figure below). Using the ratio of Time A and Time
B allows for counting of a fraction of the flow meter pulse.
K = K Factor, or counts per unit Volume, from the flow meter.
A = Time for displaced volume.
B = Time for whole meter pulses.
C = Total number of whole meter pulses.
D = Displaced Volume
Crude refined products use API 2540 equation 5, 6 A & B, 23, 4 A & B, 11-2-1, and 11-2-2. Table 24 C is
used when thermal expansion coefficient is known. Old tables 23 and 24 with GPA16 and 11-2-2 are used
for NGL or light hydrocarbon mixes. API 2565 is used for propylene, and ethylene. In addition, NBS
1045 can be selected for ethylene calculations. ASTM 1550 can be used for butadiene.

CHAPTER 2: Data Entry
and Configuration Menus
Introduction to the Smart Flow Computer Software
Introduction to the Flow Computer Software
Your SFC3 software is constructed around a menu-driven organization. Begin your software and, across
the top of your screen, you see a bar like this:
This is called the menu bar. It consists primarily of series of topics–Port, Diag, and so forth. When
you move the cursor to a topic you will see a list–we will call it a menu list– of topics related to the main
topic on the menu bar.
At the bottom of the screen is the prompt bar. It informs you of appropriate actions that you can perform
while your cursor is at its present location. In this example:
you are informed that your valid choices are the four arrow (, , , and )keys, the ENTER key,
and the key.
Another important area of the screen is the filename area. This is the rightmost section of the menu bar; it
informs you what configuration file you are presently viewing and editing. In the example above, you are
editing the file mainunits. When you first begin the SFC sotware, however, it will display
because no file has yet been chosen. Until you choose a file to edit or view, by opening either an existing
file or a new one, you will not be able to move from the File menu item.
The center portion of the screen is simply called the viewing area. Here you view either various menu lists
or the prompt window associated with an item in a menu list after it is selected (that is, after you press
ENTER). When you are in a prompt window the message appears in the filename area.
Under certain conditions you will have a screen where the viewing area takes up the whole screen and the
menu and/or prompt bars disappear. Examples of these are: the wiring diagrams, the calibration windows,
and the Diag windows.

FILE
Open a File
Use this function to open an existing configuration file. After a file is opened it becomes the currently
active file; its contents can be viewed and its parameters can be edited.
Open a New File
Create a new file to store all the programmed information for one Flow Computer. You are prompted for
the new file’s name of eight characters or less. If you enter the name of a pre-existing file, the software
informs you of this and prompts you for your file’s name again. After a file is opened it becomes the
currently active file; its contents can be viewed and its parameters can be edited.
Delete a File
Delete a file when that file is no longer needed.
When this function is chosen a list of existing configuration files is displayed. Use the arrow keys to move
the cursor to your selection, then press to delete the file.

Load File
Use this function to exchange parameter values between the PC and the Flow Computer. After this action
is performed all parameter values in the Flow Computer and the currently active file in the PC are identical.
To read all current parameters from the Flow Computer to the currently active file in the PC, press the function key; this is called “uploading”.
To write all current parameters from the currently active file in the PC to the Flow Computer press the function key; this is called “downloading”.
View File
Unlike every other file function, View File does not act upon configuration files. Instead, View File allows
the user to view files that were previously captured in a report. For capturing data in a report, look for
these items under the Report menu header:
Prev. Hourly Data
Prev. Daily Data
Alarm Data
Audit Trail Report
TicKet Report
Auto Data Retrieval
Current Data
When viewing a file use PageUp and PageDown to browse through it.
Save As
Use Save As to save the parameters in the currently active file (that is, the parameter values currently being
edited) to a new file. You are prompted for the new file’s name of eight characters or less. If you enter the
name of a pre-existing file, the software informs you of this and prompts you for your file’s name again.
The original file will remain in memory.

PORT
PC Communication Set Up
Communication Port Number (1,2,3,4)
Enter the PC port used to communicate with the Flow Computer.
Flow Computer Port Number
There are two available ports in the Flow Computer. Port 1 is the RS-485 Modbus port. Port 2 is the RS232 Modbus port. The PC set up must match the Flow Computer port set up.
Unit ID Number
The Unit ID Number is used strictly for communication purposes; it can take any value from 1 to 247. Only
one master can exist in each loop.
Note: Do not duplicate the Unit ID number in a single communication loop!
This situation will lead to response collisions and inhibit communications
to units with duplicate ID numbers.
Modbus Type
Note: this parameter must be set the same for both the PC and the Flow
Computer for communication to occur.
The Modbus Communication Specification is either Binary RTU or ASCII.
Parity
Note: this parameter must be set the same for both the PC and the Flow
Computer for communication to occur.
RTU - NONE
ASCII - EVEN or ODD
Set the parity to match the Modbus Type.
Baud Rate
Note: this parameter must be set the same for both the PC and the
Flow Computer for communication to occur.
Date: 8/1/2019
Dynamic Fluid Measurement SFC3 Liquid Pulse Manual Data Entry 2-6
Baud rate is defined as number of bits per second. The available selections are 1200, 2400, 4800, or 9600.
Transmit Delay
This Delay in milliseconds is used to allow hand shaking between the PC and the Flow Computer. The PC
will hold the RTS line high for the specified Transmit Delay time. After that time expires the data stream
will begin transmitting. Transmit Delay is applicable regardless of the type of communication with the
Flow Computer (RS-232 or RS-485).
This function can be very useful, especially when using a half-duplex RS-485 port; it allows the RS-485
port to turn off. A delay of 50 milliseconds is normally sufficient.
RTS can also be used as transmit line to printer. (RTS to Pin2, Common to Pin7)
Flow Computer Communication Set Up
Unit ID Number
The Unit ID Number is used strictly for communication purposes; it can take any value from 1 to 247.
Note: Do not duplicate the Unit ID number in a single communication
loop! This situation will lead to response collisions and inhibit
communications to units with duplicate ID numbers.
Only one master can exist in each loop.
Port #1 Modbus Type
Note: this parameter must be set the same for both the PC and the
Flow Computer for communication to occur.
The Modbus Communication Specification is either Binary RTU or ASCII.

Flow Computer for communication to occur.
RTU - NONE
ASCII - EVEN or ODD
Set the parity to match the Modbus Type.
Port #1 Baud Rate
Note: this parameter must be set the same for both the PC and the
Flow Computer for communication to occur.
Baudrate is defined as number of bits per second. The available selections are 1200, 2400, 4800, or 9600.
Port #1 RTS Delay
This function allows for a modem or radio delay time before transmission. The Flow Computer will turn
the RTS line high before transmission for the entered time delay period.
Port #2 Modbus Type
Note: This parameter must be set the same for both the PC and the
Flow Computer for communication to occur.
The Modbus Communication Specification is either Binary RTU or ASCII.
Port #2 Parity
RTU - NONE
ASCII - EVEN or ODD
Set the parity to match the Modbus Type.
Port #2 Baud Rate
Baud rate is defined as number of bits per second. The available selections are 1200, 2400, 4800, or 9600.
Select 0=RTS,1=Printer
RTS line has dual function selection; either RTS for driving request to send or transmit to serial printer.
To use serial printer interface for printing reports, ie.batch, daily, interval and proving. Connect the serial
printer pin2 to RTS and common return to pin7 and select 1 for printer.
Port #2 Number of Nulls
This function is used because no hand shaking with the printer is available and data can become garbled as
the printer’s buffer is filled. The Flow Computer will send nulls at the end of each line to allow time for
the carriage to return. Printers with large buffers do not require additional nulls. If data is still being
garbled, try reducing the baud rate to 1200.
Dial
Use the cursor arrow
keys to move the cursor to the desired phone number and press ENTER. Dial’s display indicates the
owner of each phone number according to the Phone Book.

DIAG
Read Single Flow Computer Communication Setup
Press and the configuration program will attempt to communicate with a single Flow Computer at
different baud rates and formats.
Failure to communicate can occur because of a communication wiring problem, wrong PC port selection,
communication parameter mismatch between PC and Flow Computer (Modbus type, parity, baud rate,
etc.) or lack of power to the Flow Computer. To use this feature, the user must insure that only one Flow
Computer is connected to the PC. More than one Flow Computer in the loop will cause data collisions and
unintelligible responses.

331 chip is generally used for Ball provers with dual detector switches like most traditional prover
controllers, one switch for start and one to stop. It also supports Active High single detector provers.
Single Detector Delay
When single detector is used. Hysteresis time is required to insure proper debounce time. 100 milliseconds
are sufficient in most cases.
DET ECTOR MOUNTING
When piston type prover is selected, the detector switches distance will change with temperature. For
ballistic provers, the user must select "on calibration section mounting". Pipe provers are normally "off
calibration section mounting".
Prove Seal
When prover seal signal is not available. The option for requiring prove ready signal is waived.
NUMBER OF PROVE RUN S TO AVE RAGE
Numbers 1-10 are for the consecutive runs to achieve good meter factor and pulse deviation within set
limit. After the number of prove runs to average is achieved within the pulse deviation limit, then the prove
runs will stop.

Day start hour is used for batch operation. If daily batch is selected, the batch will end at day start hour, all
batch totalizers and flow weighted values are reset.
Company Name
Up to 20 characters. The company name appears in the reports.
Flow Rate Average Second
Flow rate averaged 1-10 is for fluctuating flow rate conditions. This number is used to perform averaging
on the current flow rate by adding it to the previous seconds flow rate, and then display an averaged
smoothed number. Only low resolution pulse meter requires this function.
Old Table Gravity Unit
If old table 23/24 is selected, and gravity units are required in API units
Disable Alarms
When the alarm function is disabled, alarms will not be logged. Alarms are also not logged if turbine
frequency is below cut of limit.
Print Intervals in Minutes
When the second port of Flow Computer is configured as printer port, then a snapshot report can be
printed at any minute combination. (i.e. every five minutes, every hour, or every ten hours).
GM/CC Conversion Factor
This factor is used to reference the density to density of water (i.e. .999012) to establish specific gravity.
Weight of H2O in Vac @60 Deg.F
The weight of one barrel of water under vacuum conditions. (i.e. 350.1616 Lb/barrel)
Atmospheric Pressure
Local pressure or contracted atmospheric pressure. (i.e. 14.73 psi)
Pulse Output Width
Pulse Output Width is the duration, in milliseconds, of one complete pulse cycle (where each cycle is the
pulse plus a wait period, in a 50/50 ratio). For example: if POW = 500 msec, the Flow Computer at most
can produce one pulse each second regardless of the pulse per unit volume selected (500 msec pulse + 500
msec wait). If POW = 10 msec the Flow Computer can produce up to 50 pulses per second.
The Flow Computer’s maximum pulse output is 125 pulses/sec. The Pulse Output in combination with the
Pulse Output Width should be set so that this number is not exceeded.

Switch Output Assignment
I/O | Switch Output Assignment
The Flow Computer switch outputs are open collector type and require external D.C power. Assignment 15 are for pulse output. Assignment in the "Other Parameters" menu are ON/OFF type outputs. Switch 1-5
can be pulse or contact type output, switch 6-17 are only contact type outputs. Pulse output/unit value entry
is in other parameters assignment. PLC is required (GE 90-Micro) for switch 6-17.
ASS IGNMENTS -PULSE OUTPUTS
Pulse Output and Pulse Output Width
Pulse Output is used to activate a sampler or external totalizer. The number selected will be pulses per unit
volume or per unit mass. If 0.1 pulse is selected, the one pulse will be given every 10 unit volumes has
passed through the meter.
Pulse Output Width is the duration, in milliseconds, of one complete pulse cycle (where each cycle is the
pulse plus a wait period, in a 50/50 ratio). For example: if POW = 500 msec, the Smart Flow Computer at
most can produce one pulse each second regardless of the pulse per unit volume selected (500 msec pulse +
500 msec wait). If POW = 10 msec the Smart Flow Computer can produce up to 50 pulses per second.
The Flow Computer’s maximum pulse output is 125 pulses/sec. The Pulse Output in combination with the
Pulse Output Width should be set so that this number is not exceeded.

line feed (LF) for the end of frame
ASCII MESSAGE FORMAT
RTU FRAMING
Frame synchronization is done by time basis only. The Smart Flow Computer allows 3.5 characters time
without new characters coming in before proceeding to process the message and resetting the buffer.
To inform the slave device of what function to perform
ERROR CHECK
LRCMODE
The LRC check is transmitted as two ASCII hexadecimal characters. First, the message has to be stripped
of the: LF, CR, and then converted the HEX ASCII to Binary. Add the Binary bits and then two's
complement the result.
CRCMODE
The entire message is considered in the CRC mode. Most significant bit is transmitted first. The message is
pre-multiplied by 16. The integer quotient digits are ignored and the 16-bit remainder is appended to the
message as the two CRC check bytes. The resulting message including the CRC, when divided by the
same polynomial (X16+X15+X2+1) at the receiver, which will give zero remainder if no error, has
occurred.
EXCEPTION RESPONSE
Exception response comes from the slave if it finds errors in communication. The slave responds to the
master echoing the slave address, function code (with high bit set), exception code and error check. To
indicate that the response is notification of an error, the high order bit of the function code is set to 1.
BROADCAST COMMAND
All units listen to Unit ID Zero, and no one will respond when the write function is broadcasted.
