1. Introduction
SP4000 Flow Computer
1.1 Unit Description:
The SP4000 Flow Computer satisfies the instrument requirements
for a variety of flowmeter types in liquid, gas, steam and heat
applications. Multiple flow equations are available in a single
instrument with many advanced features.
The alphanumeric display offers measured parameters in easy
to understand format. Manual access to measurements and
display scrolling is supported.
The versatility of the Flow Computer permits a wide measure of
applications within the instrument package. The various hardware
inputs and outputs can be “soft” assigned to meet a variety of
common application needs. The user “soft selects” the usage of
each input/output while configuring the instrument.
The isolated analog output can be chosen to follow the volume
flow, corrected volume flow, mass flow, heat flow, temperature,
pressure, or density by means of a menu selection. Most
hardware features are assignable by this method.
The user can assign the standard RS-232 Serial Port for data
logging, or transaction printing, or for connection to a modem or
two way pager for remote meter reading.
A PC Compatible software program is available which permits
the user to rapidly redefine the instrument configuration.
Language translation option features also permit the user to
define his own messages, labels, and operator prompts. These
features may be utilized at the OEM level to creatively customize
the unit for an application or alternately to provide for foreign
language translations. Both English and a second language
reside within the unit.
NX-19
The NX19 feature is available for Natural Gas calculations where
the user requires compensation for compressibility effects.
Compensation for these compressibility effects are required at
medium to high pressure and are a function of the gas specific
gravity, % CO2, % Nitrogen, as well as temperature and pressure.
The compressibility algorithm used is that for NX-19.
Stacked differential pressure transmitter option
This option permits the use of a low range and high range DP
transmitter on a single primary element to improve flow transducer
and measurement accuracy.
Peak demand option
This option permits the determination of an hourly averaged flow
rate. Demand last hour, peak demand and time/date stamping for
applications involving premium billing.
Peak Demand Option
There are applications where customer charges are determined
in part by the highest hourly averaged flowrate observed during
a billing period.
The peak demand option for the SP4000 is intended for
applications where it is important to compute such an hourly
average flowrate, to note the value of the peak occurrence and
the corresponding time and date of that event.
The demand last hour rate is computed based on the current
total and the total 60 minutes prior. This value is recomputed
every 5 minutes.
The peak demand is the highest value observed in the demand
last hour.
The time and date stamp is the time and date at which the
highest peak demand occurred.
The Demand Last Hour and/or Peak Demand can be directly
viewed on the display by pressing the RATE key and then
scrolling through the rates with the ^/v arrow key until the
desired item is viewed.
The Peak Time and Date stamp can be viewed on the display
by pressing the TIME and then scrolling through the time
related parameters using the ^/v arrow keys until the desired
item is viewed.
All of these items can be included into the scrolling display list
along with the other process values and totalizers in a user
selectable list.
The peak demand may be cleared by pressing the CLEAR key
while viewing the PEAK DEMAND or by means of a command
on the serial port.
The Peak Time and Date stamp can be viewed on the display
by pressing the TIME and then scrolling through the time
related parameters using the ^/v arrow keys until the desired
item is viewed.
The Demand Last Hour and Peak Demand can be assigned to
one of the analog outputs. The demand last hour or peak
demand could thusly be output on a recording device such as a
strip chart recorder or fed into a building energy automation
system.
The Demand Last Hour and Peak Demand can be assigned to
one of the relays. The customer can be notified that he is
approaching or exceeding a contract high limit by assigning the
demand last hour to one of the relays and setting the warning
point into the set point. A warning message would also be
displayed.
The peak demand may be used in conjunction with the print list
and data logger to keep track of hourly customer usage
profiles.
The Demand Last Hour, Peak Demand, and Time and Date
Stamp information can be accessed over the serial ports. The
Peak Demand may also be reset over the serial ports.
The peak demand option may also be used as a condition to
call out in remote metering by modem or two way pager.
Data logging option
This option provides data storage information in 64k of battery
backed RAM. Items to be logged, conditions to initiate the log and
a variety of utilities to clear and access the data via the RS-232
port are provided.
EZ Setup
The unit has a special EZ setup feature where the user is guided
through a minimum number of steps to rapidly configure the
instrument for the intended use. The EZ setup prepares a series
of questions based on flow equation, fluid, and flowmeter type
desired in the application.

Measurement
The Flow Computer can be thought of as making a series of
measurements of flow, temperature/density and pressure
sensors and then performing calculations to arrive at a result(s)
which is then updated periodically on the display. The analog
outputs, 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, pressure, viscosity and density equations
are computed as needed based on the flow equation and
input usage selected by the user.

SP4000 Flow Computer
Step 3 : Compute the Volumetric Flow-
Volumetric flow is the term given to the flow in volume units.
The value is computed based on the flowmeter input type
selected and augmented by any performance enhancing
linearization that has been specified by the user.
Step 4: Compute the Corrected Volume Flow at Reference
ConditionsIn the case of a corrected liquid or gas volume flow calculation,
the corrected volume flow 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
flow rate as volume flow times density. A heat flow computation
is also made if required.
Step 6: Check Flow Alarms-
The flow alarm functions have been assigned to one of the
above flow rates during the setup of the instrument. A
comparison is now made by comparing the current flow rates
against the specified hi and low limits.
Step 7: Compute the Analog Output-
This designated flow rate value is now used to compute the
analog output.
Step 8: Compute the Flow Totals by Summation-
A flow total increment is computed for each flow rate. This
increment is computed by multiplying the respective flow rate
by a time base scaler and then summing. The totalizer format
also includes provisions for total rollover.
Step 9: 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 10: Update Display and Printer Output-
The instrument finally runs a task to update the various table
entries associated with the front panel display and serial
outputs.
Instrument Setup
The setup is password protected by means of a numeric lock
out code established by the user. The help line and units of
measure prompts assure easy entry of parameters.
An EZ Setup function is supported to rapidly configure the
instrument for first time use. A software program is also
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 standard setup menu has numerous subgrouping of
parameters needed for flow calculations. There is a well
conceived hierarchy to the setup parameter list. Selections
made at the beginning of the setup automatically affect
offerings further down in the lists, minimizing the number of
questions asked of the user.
In the setup menu, the flow computer activates the correct
setup variables based on the instrument configuration, the
flow 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.
Also note that in the menu are parameter selections which
have preassigned industry standard values. The unit will
assume these values unless they are modified 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 pressure inputs by placing the
desired nominal value into the default values and selecting
"manual". This is also a convenience when performing bench
top tests without simulators.
The system also provides a minimum implementation of an
“audit trail” which tracks significant setup changes to the unit.
This feature is increasingly being found of benefit to users or
simply required by Weights and Measurement Officials in
systems used in commerce, trade, or “custody transfer”
applications.
Simulation and Self Checking:
This mode provides a number of specialized utilities required
for factory calibration, instrument checkout on start-up, and
periodic calibration documentation.
A service password is required to gain access to this
specialized mode of operation. Normally quality, calibration,
and maintenance personnel will find this mode of operation
very useful.
Many of these tests may be used during start-up of a new
system. 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 Diagnostic
Mode:
Print Calibration/Maintenance Report
View Signal Input (Voltage, Current, Resistance, Frequency)
Examine Audit Trail
Perform a Self Test
Perform a Service Test
View Error History
Perform Pulse Output Checkout / Simulation
Perform Relay Output Checkout / Simulation
Perform Analog Output Checkout / Simulation
Calibrate Analog Inputs using the Learn Feature
Calibrate Analog Output using the Learn Feature
Schedule Next Maintenance Date
Note that a calibration of the analog input/output will advance
the audit trail counters since it effects the accuracy of the
system.

Operation of Steam Trap Monitor
In applications on Saturated Steam, the otherwise unused
Compensation Input may be connected to a steam trap
monitor that offers the following compatible output signal levels:
4mA = trap cold
12 mA = trap warm and open (blowing)
20 mA = trap warm and closed
In normal operation a steam trap is warm and periodically
opens and closes in response to the accumulation of
condensate. A cold trap is indication that it is not purging the
condensate, a trap that is constantly blowing is an indication
that it is stuck open. To avoid a false alarm, the SP4000
permits the user to program a delay, or time period, which
should be considered normal for the trap to be either cold, or
open. An alarm will only be activated if the trap is detected as
continuously being in the abnormal states for a time period
greater than this TRAP ERROR DELAY time.
The user selects to use the Compensation Input for Trap
Monitoring by selecting “4-20mA TRAP STATUS as the INPUT
SIGNAL for OTHER INPUT1.
The user can program the ERROR DELAY time in HH:MM
format into both the TRAP ERROR DELAY (cold trap error)
menu and the TRAP BLOWING DELAY (trap stuck open)
menu.
The SP4000 will warn the operator of a TRAP ERROR when
an abnormal condition is detected. The error can be
acknowledged by pressing the ENTER key. However, the
problem may reassert itself if there is a continued problem
with the steam trap.
SP4000 Flow Computer
The user can also define whether he just wants the data
stored into the datalogger, or if he wants the data both stored
in the datalogger and sent out over the RS232 port in the
DATALOG ONLY menu.
The user can define the format he wishes the data to be
output in using the DATALOG FORMAT menu. Choices are
PRINTER and DATABASE. PRINTER format will output the
data records in a form suitable to dump to a printer. DATABASE
format will output the values in a CSV, or Comma Separated
Variable with Carriage return delimiting of each record.
A number of serial commands are also included to access
and manipulate information stored with in the datalogger.
Among these RS232 command capabilities are the following
actions:
Clear Data Logger
Send all Data in Datalogger
Send Only New Data since Datalogger was last Read
Send Data for the date included in the request
Send the column heading text for the CSV data fields
Send the column units of measure text for the CSV data
fields
Store one new record into datalogger now
Read Number of New Records in the datalogger
Read number of records currently in the datalogger
Read the maximum number of records capacity of the
datalogger
Move Pointer Back N records
Dump Record at Pointer
Dump records newer than pointer
Dump data from N records back
In addition, the event is noted in the ERROR LOG.
It is also possible for the user to program a trap malfunction
as one of the conditions worthy of a CALL OUT of a problem
by selecting this error in the ERROR MASK.
The Data-Logging option of the SP4000 can also be used to
log the performance of the trap by storing the % of time the
trap has been cold, and/or blowing open during the datalog
interval.
Datalogging Option
The Datalogging Option for the SP4000 permits the user to
automatically store sets of data items as a record on a periodic
basis. A datalog record may be stored as the result of either a
PRINT key depression, or an INTERVAL, or a TIME OF DAY
request for a datalog.
The user defines the list of items to be included in each
datalog by selecting these in the PRINT LIST menu located
within the COMMUNICATIONS SUBMENU.
The user selects what will trigger a datalog record being
stored in the PRINT INITIATE menu. The choices are PRINT
KEY, INTERVAL, and TIME OF DAY.
The user can select the datalog store interval in a HH:MM
format in the PRINT INTERVAL menu.
The datalogger option is used in conjunction with the RS-232
port in remote metering applications.
The technical details associated with the serial commands
are listed in Universal Serial Protocol Manual available upon
request.
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
Remote Metering by Modem
Remote Metering by Two Way Pager
Computer Communication Link
Configuration by Computer
Print System Setup
Print Calibration/Malfunction History
Instrument Setup by PC’s over Serial Port
A Diskette program is provided with the Flow Computer
that enables the user to rapidly configure 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.
The user can also select the store time of day in a 24 hr
HH:MM format in the PRINT TIME menu.

SP4000 Flow Computer
Operation of Serial Communication Port with Printers
The 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 defines 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.
In data logging, the user defines 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 list all the
instrument setup parameters and usage for the current
instrument configuration. In addition, the Audit trail
information is presented as well as 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.
Operating Serial Communication Port with Modems
The SP4000 offers a number of capabilities that facilitate
its use with modems. The SP4000’s RS232 port can be
connected to a modem in order to implement a remote
metering system that uses either the phone companies
standard phone lines or cellular telephone system. In
addition to remote meter readings, the serial commands
may also be used to examine and/or make setup changes
to the unit, and to check for proper operation or investigate
problems. Several hundred commands are supported. A
compatible industrial modem accessory and interconnecting
cabling is offered in the MPP2400N specifically designed
for use with the SP4000.
The SP4000 and Modem can be used together to create
systems with one or more of the following capabilities:
1. Poll the SP4000 unit for information from a remote
PC.
2. Call Out from the SP4000 unit to a remote PC on a
scheduled reading time and/or crisis basis
3.Some combination of the above two descriptions where
the unit is polled by one PC and calls into to a different
PC if a problem is detected.
In fact, up to five ST-2 units can share the same modem.
Each SP4000 must have a unique DEVICE ID. This
multidropping of flow computers on a single modem is
popular when there are several flow computers mounted
near each other.
In most applications using modem communications, the
SP4000’s RS232 USAGE is first set equal to MODEM.
Each SP4000 on a shared modem cable is given a unique
serial device address or DEVICE ID. The BAUD RATE is
commonly set to 2400, the PARITY set to NONE, and the
HANSHAKING set to NONE to complete the basic setup.
The remote PC’s communication settings are chosen to
match these.
The level of complexity of the Supetrol-2 to Modem
connection can range from simple to more complex.
In a simple system a remote PC will call into the telephone
number of the modem. The modem will answer the call,
and establish a connection between the SP4000 and the
remote PC. An exchange of information can now occur.
The SP4000 will act as a slave and respond to commands
and requests for information from the remote MASTER
PC. The MASTER PC will end the exchange by handing
up.
However, it is more common that the SP4000 will be used
to control the modem. In these applications the following
communication menu settings would be used:
RS232 USAGE = MODEM
DEVICE ID, BAUD RATE, PARITY, and
HANDSHAKING are set
MODEM CONTROL = YES
DEVICE MASTER = YES (When multidropping
several SP4000's, only one unit will be the DEVICE
MASTER)
MODEM AUTO ANSWER = YES (This instructs the
unit to answer incoming calls)
HANG UP IF INACTIVE = YES (This instructs the
unit to hang up the line if no activities occur within
several minutes).
A more complex form of a remote metering system can be
implemented where the SP4000 will initiate a call to contact
the remote PC at a scheduled time and/or in the event of a
problem that has been detected. In these applications the
SP4000 has additional setup capabilities including:
The SP4000 must have a unique identifier assigned
to it (using the TAG NUMBER)
Call Out Telephone number must be entered in the
CALL OUT NUMBER
The scheduled call out time for the daily reading
must be entered in CALL OUT TIME
A decision must be made whether the unit will be
used to call on error(s) in CALL ON ERROR
The particular error conditions to call out on must be
defined in the ERROR MASK
The NUMBER OF REDIALS to be attempted if line
is busy must be entered in that cell
HANG UP IF INACTIVE= YES will disconnect the
call if remote computer does not respond.

SP4000 Flow Computer
Consult the Universal Serial Commands User Manual for
details on the individual commands supported by the
SP4000. Contact the SPONSLER Flow Applications Group
for a discussion on the remote metering system capabilities
you are considering.
NOTE: Some modems can be configured in advance to
answer incoming calls, terminate phone connections if
communications is lost. In such applications there may be
no need for the SP4000 to be functioning to “control” the
modem. Setting the RS233 USAGE = COMPUTER will
likely work.
Operating Serial Communication Port with Two Way
Paging
The SP4000 offers a number of capabilities that facilitate
its use with two way paging systems. The SP4000’s RS232
port can be connected to a compatible two way pager
transceiver in order to implement a wireless, two way
paging, remote metering system. A compatible, industrial
Two Way Pager Transceiver accessory is offered in the
TWPNW specifically designed for use with the SP4000. A
monthly service contract with a two way paging provider,
for example Skytel, is required. The remote user or system
sends or receives information from the SP4000 using either
a Two Way Pager, such as Motorola’s Pagerwriter 2000
pager, or by email via the INTERNET.
In addition to obtaining remote meter readings, the serial
commands may also be used to examine and/or make
setup changes to the unit, and/or to check for proper
operation or investigate problems. Several hundred
commands are supported.
The SP4000 and TWPNW can be used together to create
systems with one or more of the following capabilities:
1. Poll the SP4000 unit for information from a remote PC
over the Internet via email.
2. Call Out from the SP4000 unit to a remote PC on a
scheduled reading time and/or crisis basis by email
and the internet
3.Some combination of the above two descriptions where
the unit is polled by one PC and calls into to a different
PC or pager if a problem is detected.
In fact, up to five ST-2 units can share the same Two Way
Pager. Each SP4000 must have a unique DEVICE ID. This
multidropping of flow computers on a single Two Way
Pager is popular when there are several flow computers
mounted near each other.
To setup the information to be sent in this example:
Setup your desired PRINT LIST
Setup what will initiate the storage of information in
the PRINT INITIATE menu
Setup any related parameters: PRINT INTERVAL or
PRINT TIME
Set DATALOG ONLY= YES if data records will
be sent at a later time
= NO if data records will be
sent immediately as well as
being stored
Set DATALOG FORMAT = PRINTER
To setup the communication channel, the following
communication menu settings would be used:
RS232 USAGE = PAGER
Set the DEVICE ID,
BAUD RATE= 9600,
PARITY= NONE,
HANDSHAKING=NONE
DEVICE MASTER = YES (When multidropping
several SP4000, only one unit will be the DEVICE
MASTER)
CALL OUT NUMBER = <email name of receiver> or
<PIN of receiving PAGER>
CALL OUT TIME = time of a scheduled call out in
HH:MM format (if used set a different call
out time to each unit, several hours apart)
NUMBER OF REDIALS = 3 (if there is poor coverage
unit will try to up to 3 times)
PAGER PIN NUMBER = <enter the Pager Pin
Number given you by Skytel >
DESTINATION TYPE= E-MAIL (or PAGER PIN if
pager or mailbox)
MAX BLOCK SIZE = 3 (This is number of blocks (1-
4) of 128 bytes to be sent in each message.
A smaller number of blocks increases the
chance of successful communication
transfers.
If you also wish the unit to CALL OUT in the event of a
problem, the following menu settings would be used:
CALL ON ERROR = YES
ERROR MASK configured to suit the applications
needs
The SP4000’s RS232 USAGE is first set equal to PAGER.
Each SP4000 on a shared PAGER is given a unique serial
device address or DEVICE ID. The BAUD RATE is
commonly set to 9600, the PARITY set to NONE, and the
HANSHAKING set to NONE to complete the basic setup.
In a simple system, the SP4000 will send an email to an
address programmed into the unit. The recipient will receive
a daily email report containing the information desired in
the form of a readable report.

SP4000 Flow Computer
Initial Installation and Startup
When a SP4000 / TWP pair are first put on line, several
service actions are required. These include:
1. Allow time for the SP4000 to charge the batteries in
the TWPNW (see note below)
2. Set up an account with Skytel and choose a suitable
service plan for this application
3. Initializing the Pager using the SP4000 INITIALIZE
PAGER utility
4. Registering the pager with Skytel using the SP4000
REGISTER PAGER utility
5. Observe a sample exchange of information between
the SP4000 and the remote user using the CLP
PROGRESS
NOTE: It is important to wait 24 hours for the Two Way
Pager Transceiver to charge its batteries prior to
initial use. Otherwise irradic problems may occur
during registration.
Special Utilities for steps 3, 4, and 5 are built into the
SP4000. These may be summarized as follows:
INITIALIZE PAGER = YES causes the SP4000 to send
commands to initialize the pager. The
responses to the command can be either
SUCCESS if all is well or FAILED if a
problem is detected.
REGISTER PAGER = YES causes the SP4000 to attempt
to establish a connection with a local Skytel
tower. A series of informative messages
will appear as the SP4000 attempts to
register your PAGER PIN NUMBER with
Skytel. Note that your service plan must be
setup with Skytel before attempting to
register the pager.
The responses to the command can be
either SUCCESS if all is well or FAILED if a
problem is detected.
A more complex form of a remote metering system can be
implemented where the SP4000 will initiate a call to a
“mailbox” at Skytel. The Remote PC can access his mailbox
and read and process the various messages over the
internet as part of a customer billing system. Skytel offers a
software developers kit for customers wishing to create
custom solutions.
In each message, the SP4000 provides a header containing
information that can be used to determine such items as:
1. What is the TAG NO of the device that sent the
information?
2. What is its SENSOR SN
3. What is its DEVICE ID?
4. What type of message follows?
a. Exception Report (Message Type-1)
b. Send one Data Set (Message Type 2)
c. Send all new Datalog Data Sets (Message type 3)
5. What is the time and data of the first data record?
6. What information is contained in the data fields of CSV
that follow?
7. Message Delimiter (CRLF)
8. For commands returning data, the data now follows in
a CSV format
Consult the Universal Serial Commands User Manual for
details on the individual commands supported by the
SP4000.
Contact the SPONSLER Flow Applications Group for a
discussion on the remote metering system capabilities you
are considering.
RS-485 Serial Port (optional)
The RS-485 serial port can be used for accessing flow
rate, total, pressure, temperature, density and alarm status
information. The port can also be used for changing presets
and acknowledging alarms.
CLP PROGRESS is a diagnostic menu location that
provides information on the information
exchanges for test purposes (see CLP
Progress Menu in chapter 6). Contact the
applications group at SPONSLER if
problems are encountered in initial setup or
use of two way paging applications.

General Mounting Hints
Mounting Procedure
NEMA4X / IP65 Specifications
2.1 General Mounting Hints:
The SP4000 Flow Computer should be located in an area with a clean, dry
atmosphere which is relatively free of shock and vibration. The unit is installed in a
5.43" (138mm) wide by 2.68" (68mm) high panel cutout. (see Mounting Dimensions)
To mount the Flow Computer, proceed as follows:
a. Prepare the panel opening.
b. Slide the unit through the panel cutout until the it touches the panel.
c. Install the screws (provided) in the mounting bracket and slip the bracket over the
rear of the case until it snaps in place.
d. Tighten the screws firmly to attach the bezel to the panel. 3 in. lb. of torque must
be applied and the bezel must be parallel to the panel.
NOTE: To seal to NEMA4X / IP65 specifications, supplied bezel kit must be used
and panel cannot flex more than .010".
When the optional bezel kit is used, the bezel adaptor must be sealed to the
case using an RTV type sealer to maintain NEMA4X / IP65 rating.

5.8 RS-232 Serial Port Operation
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). Enhanced
uses include remote metering by modem or two way pager.
5.8.1 PC Communications:
The Setup Disk also allows the user to query the unit for operating status such as Flow
Rate, Flow Total, Temperature, Pressure, Alarm Setpoints, etc.
In this mode of operation the RS232 port is assumed connected to a
computer. The SP4000 will act as a slave and answer requests from the PC. See
the Universal Protocol Users Manual for a complete listing of the commands
set supported. A DDE/OPC Server is also available for use in exchanging
information with DDE Clients such as Spread Sheets, Database Programs, and
HMI software.
5.8.2 Operation of RS-232 Serial Port with Printers:
Transaction Printing
For transaction printing, the user defines the items to be included in the printed
document (see section 6.13 COMMUNICATION, Print List). The transaction document
can be initiated by pressing the PRINT key.
Data Logging
The user can select when (time of day) or how often (print interval) the data log is to be
made (see section 6.13 COMMUNICATION, Print Initiate). Information will be stored to
the datalogger and optionally output to the RS-232 port.
System Setup and Maintenance Report
The system setup and maintenance report lists all of the instrument setup parameters
and usage for the current instrument configuration. The audit trail information and a
status report is also printed. This report is initiated in the Service and Analysis Group
(see section 6.15 SERVICE & ANALYSIS, Print System Setup).

5.8.3 Operation of RS-232 Serial Port with Modems and Pagers
Modem
In this mode of operation the RS232 port is assumed to be connected to a telephone
modem. The SP4000 is responsible for communicating to a remote computer through the
modem to perform such actions as:
Answer incoming calls, process requests for information or action items or data log
contents or change setup parameters, call out daily readings to designed phone number,
call out to designated phone number in the case of a designated exception or malfunction
in the unit, terminating telephone calls if a connection is lost.
Two Way Paging
In this mode of operation the RS232 port is assumed to be connected to a Two Way Pager
Transceiver. The SP4000 is responsible for communicating to the pager to perform such
actions as:
Look for and process requests for information or change setup parameters, call out daily
readings to designed pager/email address, call out to designated pager/email address in
the case of a designated exception or malfunction in the unit.
5.9 RS-485 Serial Port Operation
The RS-485 serial port is intended to permit operation of the flow computer in a RS-485
network. Access is limited to reading process variables, totalizers, error logs and to
executing action routines such as clearing totalizers, alarms, and changing setpoints.
5.10 Pause Computations Prompt
The user will be prompted with a "Pause Computations" message when making significant
setup changes to the instrument. Pausing computations is necessary to make any
significant changes. With computations paused, all outputs assume a safe state equal
to that of an unpowered unit. Computations resume when exiting the setup menu.

SP4000 Flow Computer
6. PROGRAMMING
6.1 Front Panel Operation Concept for Program Mode
The SP4000 is fully programmable through the front panel. The instrument setup menu
structure is based on a number of topical submenu groups with one submenu group for
each instrument function. Each submenu contains all of the individual settings associated
with that function. During the instrument setup, setup topics are shown on the bottom
line of the display while the detailed selection options are shown on the top line. A help
menu is available for each menu item.

LINEARIZATION
FLOW INPUT
With many flowmeters, the relationship between the flowrate and the
output signal may deviate from an ideal curve (linear or squared).
The flow computer is able to compensate for this documented
deviation using a linearization table.
The appearance of the linearization table will vary depending on
particular flowmeter selected.
Linear flowmeters with pulse output
The linearization table enables up to 16 different frequency & K-factor
pairs. The frequency and corresponding K-factor are prompted for
each pair of values. Pairs are entered in ascending order by frequency.
Linear Flowmeters with pulse outputs and a UVC Curve:
The linearization table enables up to 16 different Hz/cstks and KFactor points. The Hz/cstks and corresponding K-Factors are
prompted for each pair of values. Pairs are entered in ascending
order by Hz/cstks.
Linear flowmeters with analog output
The linearization table enables up to 16 different flowrate &
correction factor pairs. The flowrate and corresponding correction
factor are prompted for each pair of values. The correction factor (kf)
is determined as follows.
Kf =
actual flowrate

7. Principle Of Operation
SP4000 Flow Computer
General
Operation
Square Law
Flowmeter
Considerations
7.1 General:
The SP4000 Flow Computer uses several internal calculations to compute the compensated flow based on specific data input. Several computations are performed to
arrive at the uncompensated flow, temperature, pressure, density and viscosity. This
information is then used to compute the Corrected Volume Flow, Mass Flow or Heat
Flow.
7.2 Square Law Flowmeter Considerations:
Head class flowmeters are supplied by the manufacturers with a 4-20 mA output span
which is already in flow units. The SP4000 permits the user to enter this flowmeter
information directly. However, closely associated with this information is the density
that was assumed during flowmeter calibration. This information must also be input if
the user is to obtain maximum accuracy.
It is assumed that the user has the printout from a standardized sizing program for the
particular device he will be using. Such standardized printouts list all the necessary
information which the user will then be prompted for.
Several specialized flow equations are listed that are not intended for the standard
unit but to be offered to appropriate OEMs or as special order items. These are
designated by a “†”.
