Operating Mode
The Flow Computer can be thought of as making a
series of measurements of ow, temperature/density
sensors and then performing calculations to arrive
at a result(s) which is then updated periodically on
the display. The analog output, the pulse output,
and the alarm relays are also updated. The cycle
then repeats itself.
Step 1: Update the measurements of input
signals-
Raw Input Measurements are made at each input
using equations based on input signal type selected.
The system notes the “out of range” input signal as
an alarm condition.
Step 2: Compute the Flowing Fluid Parameters-
The temperature, viscosity, and density equations
are computed as needed based on the ow equation
and input usage selected by the user.
Step 3 : Compute the Volumetric Flow-
Uncompensated ow is the term given to the ow in
volume units. The value is computed based on the
owmeter input type selected and augmented by
any performance enhancing linearization that has
been specied by the user.
Step 4: Compute the Corrected Volume Flow at
Reference Conditions-
In the case of a corrected liquid volume ow
calculation, the corrected volume ow is computed
as required by the selected compensation
equation.
Step 5 : Compute the Mass Flow-
All required information is now available to compute
the mass ow rate as volume ow times density.
Step 6: Check Flow Alarms-
The ow alarm functions have been assigned to
one of the above ow rates during the setup of the
instrument. A comparison is now made by comparing
the current ow rates against the specied hi and
low limits.
Step 7: Compute the Analog Output-
This designated ow rate value is now used to
compute the analog output.
Step 8: Compute the Flow Totals by Summation-
A ow total increment is computed for each ow
rate. This increment is computed by multiplying
the respective ow rate by a time base scaler and
then summing. The totalizer format also includes
provisions for total rollover.
Step 9: Total Preset Comparisons-
The total associated with a preset function is then
compared against the corresponding preset value
and any required control actions taken.
Step 10: Pulse Output Service-
The pulse output is next updated by scaling the total
increment which has just been determined by the
pulse output scaler and summing it to any residual
pulse output amount.
Step 11: Update Display and Printer Output-
The instrument nally runs a task to update the
various table entries associated with the front panel
display and serial outputs.

SUPERtrol-I MS-716 Flow Computer
Setup Mode
The setup mode is password protected by means
of a numeric lock out code established by the user.
In addition, a secret, manufacturers numeric unlock
entry sequence is available.
The system also provides a minimum implementation
of an “audit trail” which tracks signicant setup
changes to the unit. This feature is increasingly
being found of benet to users or simply required
by Weights and Measurement Ofcials in systems
used in commerce, trade, or “custody transfer”
applications.
A software program is available which runs on a
PC using a RS-232 Serial for connection to the
Flow Computer. Illustrative examples may be down
loaded in this manner.
The setup mode has numerous subgrouping of
parameters needed for ow calculations. There is
a well conceived hierarchy to the setup parameter
list. Selections made at the beginning of the setup
affect offerings further down in the lists.
In the setup mode, the ow computer activates the
correct setup variables based on the instrument
conguration, the ow equation, and the hardware
selections made for the compensation transmitter
type, the flow transmitter type, and meter
enhancements (linearization) options selected. All
required setup parameters are enabled. All setup
parameters not required are suppressed.
A help line prompt is provided for each entry. In
addition a help message is available which may be
accessed by depressing the “HELP” key.
In the setup mode selections, several parameters
are required to be input by the operator since these
parameters are blank when the unit is received. The
user will be prompted for these necessary values
for his application.
Also note that in the setup mode are parameter
selections which have preassigned industry
standard values. The unit will assume these values
unless they are modied by the user.
Most of the process input variables have available
a “default” or emergency value which must be
entered. These are the values that the unit assumes
when a malfunction is determined to have occurred
on the corresponding input.
It is possible to enter in a nominal constant value
for temperature or density, or analog ow inputs
by placing the desired nominal value into both the
lo and hi values. This is also a convenience when
performing bench top tests without simulators.
Maintenance Mode:
The Maintenance Mode of the Flow Computer is the
Test and Calibration Mode for the device. This mode
provides a number of specialized utilities required
for factory calibration, instrument checkout on start-
up, and periodic calibration documentation.
A password is required to gain access to this
specialized mode of operation. Normally quality,
calibration, and maintenance personnel will nd
this mode of operation very useful. It is also useful
for factory testing.
Many of these tests may be used during start-up
of a new system. Inputs signals may be read,
and output signals may be exercised to verify the
electrical interconnects before the entire system is
put on line.
The following action items may be performed in the
Maintenance Mode:
Print Calibration/Maintenance Report
Examine Audit Trail
Perform Keypad Checkout
Perform Display Checkout
Perform Pulse Input Checkout
Perform Pulse Output Checkout
Perform Control Input Checkout
Perform Relay Output Checkout
Perform Analog Input Checkout
Perform Analog Output Checkout
Calibrate Analog Inputs using the Learn Feature
Calibrate Analog Output using the Learn Feature
Battery Check
Note that a calibration of the analog input/output will
advance the audit trail counters since it effects the
accuracy of the system.
RS-232 Serial Port
The Flow Computer has a general purpose RS-232
Port which may be used for any one of the following
purposes:
Transaction Printing
Data Logging Internal Datalog Dumps
Remote Metering by Modem (optional)
Computer Communication Link
Conguration by Computer
Print System Setup
Print Calibration/Malfunction History
Remote Control
Instrument Setup by PC’s over Serial Port
A Diskette program is provided with the Flow
Computer that enables the user to rapidly congure
the Flow Computer using an Personnel Computer.
Included on the diskette are common instrument
applications which may be used as a starting point
for your application. This permits the user to have
an excellent starting point and helps speed the user
through the instrument setup.

SUPERtrol-I MS-716 Flow Computer
Operation of Serial Communication Port with
Printers
Flow Computer’s RS-232 channel supports a
number of operating modes. One of these modes
is intended to support operation with a printer in
metering applications requiring transaction printing,
data logging and/or printing of calibration and
maintenance reports.
For transaction printing, the user denes the items
to be included in the printed document. The user
can also select what initiates the transaction print
generated as part of the setup of the instrument.
The transaction document may be initiated via
a front panel key depression, a remote contact
closure, or upon completion of a batch.
In data logging, the user denes the items to be
included in each data log as a print list. The user
can also select when or how often he wishes a data
log to be made. This is done during the setup of
the instrument as either a time of day or as a time
interval between logging.
The system setup and maintenance report lists all
the instrument setup parameters and usage for
the current instrument conguration. In addition,
the Audit trail information is presented along with
a status report listing any observed malfunctions
which have not been corrected.
The user initiates the printing of this report at a
designated point in the menu by pressing the print
key on the front panel.
Operation of Serial Port with Modems (optional)
The Flow Computer RS-232 channel supports a
number of operating modes. One of these modes
is intended to support operation with a modem in
remote metering applications.
An external modem is intentionally being used
with the Flow Computer. This permits use with
the variety of modem standards worldwide while
avoiding the specialized approvals required for
equipment that is deemed to fall under the category
of telecommunication equipment.
In the modem mode, the Flow Computer is
assumed to be operating in a remote metering role.
The Flow Computer will support key items in the
Hayes Compatible “AT” Command Set. In this role,
the Flow Computer will have the following special
abilities:
0. Monitor the modem status as a task of the
system
1. Instruct the modem to answer an incoming call
ATA
2. Respond to the calling modem at a compatible
baud rate and protocol
3. Perform error checking in conjunction with the
modem
4. Monitor the status of the carrier
5. Terminate the telephone connection in event the
connection is lost.
In addition, the Flow Computer will be capable of
initiating a call to a designed telephone number in
the event of a metering malfunction.

5.2 General Operation
The unit can display: Rate, Total, Grand Total, Temperature, Density, Presets and
Time of Day. The Temperature and/or Density can be displayed even if you are
using the Volumetric Flow Equation (a Temperature or Density sensor must be
installed). The unit can perform Mass or Corrected Volume equations using a
temperature or density sensor (these equations can be computed without Temp/
Dens sensors by using user dened default values). The unit can be programmed
to perform Ratemeter/Totalizer or Batching functions (see section 6.3, SELECT
INSTRUMENT Submenu).
5.3 Ratemeter/Totalizer Operation
The Ratemeter/Totalizer mode is used primarily to monitor owrate and
accumulated total. The relays can be used to trigger ow, total, temperature or
density alarms.
5.3.1 Password Protection for Rate/Total mode
After an Operator and/or Supervisor Password is entered in the setup mode (see
section 6.3, SETUP PASSWORD submenu), the unit will be locked. The unit will
prompt the user for the password when trying to perform the following functions:
Clear Total
Clear Grand Total
Enter Menu
Edit Preset 1 (PRE 1 Key)
Edit Preset 2 (PRE 2 Key)
The Supervisor password should be reserved for supervisors. The Supervisor
password will allow access to restricted areas of the Setup and Test menus.
5.3.2 Relay Operation in Rate/Total mode
Up to four relays are available (two standard) for alarm outputs. The relays can
be assigned to trip according to rate, total, temperature, density readings or
general system alarms. The relays can be programmed for low or high alarms.
Preset 1 (RLY1) and Preset 2 (RLY2) are easily accessible by pressing the PRE
1 or PRE 2 key on the front panel. Preset 3 and Preset 4 are accessible only
through the setup menu.
5.3.3 Pulse Output in Rate/Total mode
The isolated pulse output (open collector) is menu assignable to Volume Total,
Corrected Volume Total or Mass Total. The pulse output duration can be set for
10mS (50 Hz max) or 100mS (5 Hz max). A pulse output scale factor (pulse value)
can be set to scale the pulse output. The pulse output is ideal for connecting to
remote totalizers or other devices such as a PLC. See section 1.3 for electrical
specications.
5.3.4 Analog Output in Rate/Total mode
The analog output is menu assignable to correspond to the Volume Rate,
Corrected Volume Rate, Mass Rate, Temperature, Density, Volume Total,
Corrected Volume Total or Mass Total. The analog output is ideal for "trend"
tracking using strip chart recorders or other devices.

5.3.5 RS-232 Serial Port Operation in Rate/Total mode
The RS-232 serial port can be used for programming (using the Setup Disk)
or for communicating to printers and computers in the Operating Mode (Run
Mode).
PC Communications:
The Setup Disk also allows the user to query the unit for operating status such
as Flow Rate, Flow Total, Temperature, Density, Presets, etc.
Operation of RS-232 Serial Port with Printers:
Transaction Printing
For transaction printing, the user denes the items to be included in the
printed document (see section 6.3.20 SET DATA OUTPUT, Select_list). The
transaction document can be initiated by pressing the PRINT key or by a
remote contact closure.
Data Logging
In data logging, the user denes the items to be included in each data log (see
section 6.3.20 SET PRINTER OUTPUT, Select_list). The user can also select
when (time of day) or how often (print interval) the data log is to be made (see
section 6.3.19 SET PRINTER OUTPUT, Congure).
System Setup and Maintenance Report
The system setup and maintenance report lists all of the instrument setup
parameters and usage for the current instrument conguration. The audit trail
information and a status report is also printed. This report is initiated in the
Test menu (see section 8.2.3 PRINT SYSTEM SETUP).
RS-232 Serial Port
(Rate/Total mode)
5.3.6 RS-485 Serial Port (optional)
RS-485 Port Description:
The optional RS-485 card utilizes Modbus RTU protocol to access
a variety of process parameters and totalizers. The Relays can
be controlled via Modbus. In addition, action routines can be
executed. For further information, contact factory and request
RS-485 Protocol manual.
Operation of Serial Communication Port with PC
The ow computer's RS-485 channel supports a number of
Modbus RTU commands. Modbus RTU drivers are available from
third party sources for a variety of Man Machine Interface software
for IBM compatible PC's.
The user reads and writes information from/to the RS-485 using
the Modbus RTU commands. The Flow Computer then responds
to these information and command requests.
Process variables and totalizers are read in register pairs in oating
point format. Time and date are read as a series of integer register
values. Alarms are individually read as coils. Action routines are
initiated by writing to coils.

SUPERtrol-I MS-716 Flow Computer
5.4 Batcher Operation
The Batcher mode is used primarily to control batches. The main difference between
the Batch mode and Rate/Total mode is the relay operation. The Batch mode allows
the operator to "START" the unit via the front panel or remote input. Once started,
the relays (RLY1 & RLY2) will energize and send power to a ow control device
(i.e. solenoid valve or pump). The ow sensor will send a signal to the unit and
total accumulation will begin. When the Prewarn value (PRE 2) is reached, Relay
2 will drop out (this is ideal for ow slow down). When the Batch amount (PRE 1)
is reached, Relay 1 will drop out and the Batch is complete.
Refer to Appendix B for additional diagrams for Batching concepts for conventional
two stage batching and/or batching with a Digital Control Valve.
Several messages will be displayed during normal batch operation (i.e. Batch
Fill, Batch Stopped). The keypad is disabled for the duration of these timed
messages (approx. 2 sec).
5.4.1 Batcher Conguration.
When the unit is programmed for batch mode, several batch operation choices are
available. These choices include: Up or Down Counting, Maximum Batch Preset,
Batch Overrun Compensation, Auto Batch Restart, Time Delay, Flow Signal Timeout,
Maximum Drain Time, Slow Start Quantity, Start or Reset/Start, and Stop or Stop/
Reset.
Standard Preset or EZ Preset
Use Standard Preset for applications in which the batch amount does not change
frequently.
Use EZ Preset in applications in which the batch amounts change frequently. The
EZ Preset mode was designed to enter presets with minimum key strokes.
Batch Count Mode
The Batch Count Mode allows the user to choose whether the unit will batch up to
a preset value or batch down from a preset value to zero.
Maximum Batch Preset
The Maximum Batch Preset allows the user to program the Maximum Batch value
allowed to be entered by the operator. If an operator should try to program a batch
higher then this value, the unit will not allow the value to be entered and will prompt
the user with an error message saying that the Maximum Batch Preset has been
exceeded.
Batch Overrun
The Batch Overrun is used for batch applications that have slow responding valves
and a consistent batching owrate. When the Batch Overrun is set, the unit will
compensate for batch overruns by computing an averaged overrun value from the
last four batches. This average is used to internally adjust the batch setpoint to
minimize overrun.
Flow Signal Timeout
The Flow Signal Timeout allows the user to enter a timeout of 0 to 99 seconds. If
a batch is “Filling” and zero ow persists for more than the user entered time then
the batch will be aborted. This prevents over ows due to faulty ow sensors and/
or wiring.
Maximum Drain Time
The unit declares that a batch is “done” when the ow rate equals “0”. A ow rate
may be present long after the Preset Relay de-energizes due to slow reacting valves
or leaky valves. The Maximum Drain Time allows the user to enter an amount of
time (0 to 99 seconds) to wait before declaring “Batch Done”. After the Preset Batch
quantity is reached, the unit will declare “Batch Done” when the ow rate is “0” or
the Maximum Drain Time has expired. The batch data will then be available for
printing and datalogging.
Digital Control Valve
Digital Control Valve Functions slow ll rate, fast ll rate, ll rate hysteresis are
supported. Refer to Appendix B for concept diagram.
Pump Control
Optional functions for Relay 3 include its use for Pump ON/OFF control in either one
stage, two stage or digital control valve applications.
