MODEL SP3000 MASS FLOW COMPUTER

INTRODUCTION

1.1 GENERAL DESCRIPTION

The Model SP3000 is a microprocessor based instrument designed to measure and compensate
flow in an industrial environment. Three inputs - temperature, pressure, and flow – are provided
for calculating the flow at standard conditions. Special signal conditioning circuitry is included to
allow direct connection of 2, 3, or 4 wire platinum Resistance Temperature Detectors (RTDs),
voltage inputs or current loops. A high speed digital input is provided for interfacing with the
meter mounted SP714 Pulse Amplifier. A 32 terminal strip on the rear panel provides easy
connection to the instrument.

The Model SP3000 is powered by 50 or 60 Hz, 110 or 220 VAC, switch selectable, or can be
ordered for 24 VDC power.

The Model SP3000 is designed to provide continuous, on-line, compensation for true flowrate
from volumetric flow transducers. All volumetric, mass, or heat flow calculations are taken with
permission from the Flow Measurement Engineering Handbook written by R.W. Miller. Steam
(100% quality, saturated, or superheated to 850
Steam tables.

Operator interface is through a 16 key keypad and a 2 line by 20 character liquid crystal display.
(The Model SP3000 may also be set up entirely through the optional RS-232 port). Range
selection, input filtering characteristics, scaling factors, etc. are selected through the front panel
keypad or RS-232 interface. There is no need to disassemble the unit or set any dip switches.

Scaled digital and 4-20mA analog current outputs, that represent compensated flow, are standard
for use in remote monitoring of flow. Two form C relays provide isolated flow or
temperature/pressure alarm outputs.

There is a single precision voltage reference in the unit used for all analog measurements. A
single multi-turn potentiometer is provided for factory calibration. No field adjustments are
necessary.

1.2 FEATURES

The Model SP3000 is designed to provide accurate and low cost compensated flow
measurement for industrial applications. The instrument can be set up to display volumetric,
mass, or heat flow, as well as totalized flow, with an overall accuracy of 0.25%.

PROGRAMMING CONSIDERATIONS

Run? Allows crossover from Setup to Run

Go To Standby? Allows crossover from Run to

made

Programming the SP3000 Flow Computer for the desired operation is very simple. All programming
selections and data entry are accomplished via the 16 keys located and labeled on the front panel. The
software in the unit contains two Top Level Menus: “Setup” Menu and “Running” Menu. The “Setup” Menu
allows the selection of operating parameters and entry of data variables. The “Computation” selection sets
the formulas used to process the raw input data into meaningful information. The “Engineering Units”
selection establishes the measuring system that is used for entry and display of the data. The “Hardware”
selection sets the type of input data and activates the proper input terminals on the rear of the unit. The
unit will automatically determine the setup parameter requirements based on the “Computation” and
“Hardware” selections. Prompts are displayed for entry of the required data as the operator progresses
through the setup menu. To aid in the setup, a calibration worksheet is provided. Fill out the worksheet
before beginning setup. Review this section for setup procedures and follow the worksheet for data to be
entered.

The “Running” menu allows the setup of the data display and examination of the programmed operating
parameters. The parameters may not be changed in the “Running” menu.

Either menu allows checking the alarm, clearing the totalizer, or accessing the lock.

3.551 DIGITAL PULSE – SIXTEEN POINT PROGRAMMING

C

The 16 Point Linearization is used when the flowmeter gives a non-linear signal. The unit
uses up to 16 different frequency and K-Factor entries to form a curve for linearizing the
input signal.

SPONSLER, INC. STRONGLY RECOMMENDS THOROUGH REVIEW AND
UNDERSTANDING OF THIS SECTION PRIOR TO PROGRAMMING THE 16 POINT
MENU.

NOTES:
1 A minimum of three points must be set up.

2. If two consecutive input values or K-Factors are set to zero, extrapolation is taken from
the last two non-zero points to determine a K-Factor used for calculations.

3. If the input frequency is above the highest or below the lowest frequency programmed,
the unit will use the last two points to extrapolate the K-Factor and calculate the
resulting actual flow. Care must be taken that the K-Factor doesn’t extrapolate to zero.
If this happens, the unit will give erroneous readings. To avoid this occurrence,
program point 01 frequency at zero and point 01 K-Factor at the same K-Factor for the
lowest input frequency as listed in the flowmeter calibration sheet.

4. Frequencies must be entered in ascending order.

PRINCIPLES OF OPERATION

9.1 GENERAL

This chapter explains in detail how the instrument calculates the mass flow based on specific data input.
Each parameter is updated at a 2Hz rate. Therefore, all references to the machine’s “interval” in the

following descriptions indicates a period of 0.4 seconds.

9.2 TEMPERATURE CALCULATIONS

If an RTD is used as a temperature transducer, the computer runs a constant current through both the RTD
and the internal semi-precision resistor in series with it. (See section 1.52) The computer measures the
voltage drop across each individually and calculates a ratio; thus, determining the actual resistance of the
RTD. A look-up table is used to linearize and convert the ohmic reading to temperature in degrees. This
value is checked against keyed in alarm limits and the alarm relay is activated if necessary.

Any other type of temperature transducer must present a voltage or current to Channel 1 of the computer.
This value is checked against a keyed in temperature parameters to calculate the actual temperature.

9.3 PRESSURE CALCULATIONS

Any pressure transducer must present a voltage or current to Channel 2 of the computer. The raw
pressure value is digitized from Channel 2 and then scaled according to the two keyed in pressure
parameters to calculate the actual pressure. The value is checked against keyed in alarm limits and the
alarm relay is activated if necessary.

9.4 FLOW CALCULATIONS

The value provided by the digital input pulse accumulator is divided by the K-Factor to find the
instantaneous flow over the interval. The result is then filtered according to the keyed in flow filter
parameter to get uncompensated flow.

The following definitions and calculations are used to determine Volumetric, Mass and Heat Flow.
Definition of Terms:

BR: Base Reference Temperature entered by user.
c: Thermal coefficient of expansion for the media (X 10
DENSITY: Density as calculated from parameters and inputs.
DP: Differential pressure in inches of water calculated from flow input.
FLOW: Uncompensated flow calculated from input.
HZ: Input frequency in cycles per seconds.
K: The meter calibration factor in pulses per cubic foot or gallon.
K1: Factor used in Orifice/Pitot calculations.
kPa: The absolute pressure (Gage pressure + Barometric pressure).
MASS: Mass flow rate calculated using temperature, pressure and flow. Del Heat equation uses

temp 1 for Mass calculations.
PSIA: The absolute pressure (Gage pressure + Barometric pressure).
PSIG: Upstream gage pressure calculated from input.
SG: Specific Gravity as entered by user with respect to Standard conditions or the Base

Reference temperature.
SH: Specific Heat as entered by user or from Steam Tables.
SV: Specific Volume from Steam Tables.
TEMP: Temperature as calculated from input.
UCFLOW: Uncompensated flow as determined by calculations.

If the authorized programmer of the instrument forgets the security code and is locked out, follow this procedure:

A. Scroll through the menu to the Lock/Unlock menu. Press the key.
B. At the prompt, enter the code 00000 using the keypad.
C. The instrument will display a message “CALL IN CODE” and a 5-digit number.
D. Call the manufacturer and ask for the proper Customer Service Personnel.
E. Customer Service will ask for a 5 digit CALL IN CODE and will give back a 50digit RETURN CODE that was

generated by a computer.
F. Enter this 5 digit RETURN CODE using the keypad.
G. Five chances to enter the RETURN CODE are allowed, after which this procedure will have to be repeated.
H. Once the new 5 digit code has been successfully entered, it will unlock the Flow Computer.
I. It is the programmer’s responsibility to reset the instrument with a new 5 digit lockout code.
J. If, at a later date, you are locked out of the instrument again, you will have to call and repeat this procedure. A

new CALL IN CODE will be generated by the instrument.

PULSE INPUTS ARE NOT COUNTING ON THE INSTRUMENT
A. Check the voltage of the pulses. They must be between 3-30V, and not less than 3V or negative.

GENERAL

This chapter summarizes operation of the SP3000 MASS FLOW COMPUTER with a remote terminal. It is
recommended that you read the preceding chapters of the Operating Instructions. You should be familiar with the
format and methods used in setting up the basic instrument before using the RS-232 communications option.

Setting up the RS-232 Link

The RS-232 connector is a standard 25 pin connector, and it is located at the rear of the instrument. Figure 1
shows a wiring diagram for the Sub-D 25 Pin connector. Standard inputs must present a load of 3000 to 7000
Ohms. A voltage level of +3V to +25V (reference to signal ground) is read as a “Space” or “0” and indicates an
active state (does not assert a control line). Outputs must send a voltage of +15V to +25V (reference to signal
ground) for a “Space” and a volt age of -5V to -25V for a “Mark” when loaded with a 3000 Ohm load to signal
ground. Outputs must be capable of being shorted to other signal lines without burning out. It is normally
recommended that cable length be limited to 50 feet.

Activating the Printer Busy Line on the SP3000

Two jumpers are needed to activate the printhead busy option on the RS-232 card. These jumpers are located on
the RS-232 card to the left of the 25 pin connector (looking from the back).

If Jumper 1 (JP1) is connected, the handshake option is activated. The handshake line is Pin #11 on the
RS-232 25 pin connector. Refer to Fig. 2 below.

Jumper 2 (JP2) determines whether Pin #11 is high or low when the printhead is busy. If (JP2) is installed,
then Pin #11 goes high when the printhead is busy. Refer to Fig. 3 below.

Be sure to follow case disassembly and other handling procedures outlined in this manual.

Line Oriented Data Input

A

ENT

ENT

ENT

ENT

RS-232 communication provides access to all operating parameters of the Flow Computer. The instrument
constantly monitors the RS-232 port for activity, entering the data received into an internal 80 character memory
buffer. Entry is terminated when a carriage return is entered (Return or Enter key) or when the buffer size is
exceeded. At that time, the information is parsed by the internal parser and a dispatch to the appropriate service
routine is made.

Parser

Because so much information must be typed to communicate with the instrument, a sophisticated parser has been
included to facilitate this data entry. It is very forgiving of typing mistakes. When a command is typed, the parser
finds the closest match between what is typed and the keypads stored in its memory. This memory of “parsing to
uniqueness” requires only enough information in the keyword to be able to distinguish it from the other words.

When a phrase is required to indicate a specific variable, the order of the words contained in the phrase will not
matter. Also, unnecessary words will not cause an error in phrases which may contain related but unnecessary
words.

If a phrase cannot be understood or is ambiguous, the instrument will ignore the command and an error message
will be displayed. If possible, the instrument will indicate problem areas to assist in accurate data entry on the next
try.

Line Editing:

Rudimentary line editing is acc om plishe d by using the backspace key, which will erase the prev io us charac ter, and
the Control-U and Control-C keys, will erase the entire line.

Protocol:

The instrument operates at 300, 1200, or 9600 baud, with 8 bits, 1 stop bit, and no parity. The remote terminal or
computer should be configured appropriately.

Getting started:

The baud rate and the unit identification number must be set up via the front keypad on the SP3000.
In the Setup Mode:

SET COMPUTATIONS

Reference: See Section 3.2
Format: SET COMPUTATIONS [text] (CR)
Function: Computation units set depending on text string:
REQUIRED TEXT

VOLUME (Ideal Gas-Volume)
MASS (Ideal Gas-Mass)
STEAM (Steam Tables- Mass)
LIQMASS (Liquids- Mass)
LIQVOL (Liquids- Volume)
HEATGAS (Heat- Gas)
HEATSTEAM (Heat- Steam)
HEATLIQUID (Heat- Liquid)
DEL HEAT (Del Heat- Liquids)

Example: SET COMPUTATIONS HEATSTEAM (CR)

SET UNITS

Reference: See Section 3.4
Format: SET HARDWARE [text] (CR)
Function: The SET HARDWARE command parallels the Hardware Setup menu. The user may

configure the input hardware using this command.

58

The command consists of the word SET HARDWARE, followed by the word FLOW, TEMPERATURE, or
PRESSURE, and then by the input characteristics desired. Key input characteristics are 5V, 10V, 4-20mA, 0­20mA, RTD, and DIGITAL.

Note that RTD may be used only on temperature input, and DIGITAL may be used only on the flow input.
When configuring the flow channel, the (optional) final word is used to indicate the type of meter being used, and

may be either LINEAR or ORIFICE/PITOT, as required. If this qualifier is omitted, the type is not changed.
EXAMPLES:

SET HARDWARE Pressure 10V (CR)
SET HARDWARE Temperature 4mA (CR)
SET HARDWARE Flow Digital (CR)
SET HARDWARE Flow 4-20 Orifice (CR)

SPECIFIC PARAMETERS SET COMMANDS

Function: The SET command can also be used to set miscellaneous parameters in the instrument. With a

SET command, a numerical argument must follow.

USING THE SET COMMAND:

To set one of the instrument’s preset variables, the instrument will parse the phrase following the word SET to find
the specific preset variable to access.

Certain keywords are required to uniquely identify a variable:

FLOW FACTOR OUTPUT
TEMPERATURE ALARM HIGH
PRESSURE LIMIT LOW
SCALE INPUT FILTER

The phrase must be followed by a decimal number of an appropriate value.
Examples of legitimate SET phrases are as follows:
SET K factor to 1.0123 (CR)

SET flow low input scale to 0 (CR)
SET flow hi input scale to 100 (CR)
SET flow low alarm to 0 (CR)
SET flow hi alarm to 1000.0 (CR)
SET low temperature scale input to –10 (CR)
SET hi scale input of temperature to 100 (CR)
SET output digital scaling at 10 (CR)

NOTE: (CR) indicates the ENTER or RETURN key of the terminal.
After each successfully parsed phrase, the instrument will immediately show the variable that has been changed

and the new value to which it has been set.
If a phrase cannot be understood or is ambiguous , the unit will give an err or m es sage.

For example:
SET flow temperature to 12 (CR)

59

The instrument will not understand this command and will give a “Syntax Error” message. The problem with this
command is that it does not specify to setup alarm or scale.

A more subtle type of problem with a command is as follows:
SET flow alarm to 100 (CR)
This phrase will also generate a “Syntax Error” because it is unclear whether the LOW flow alarm or the HIGH flow

alarm is to be accessed.
Reference: See Section 3.5

REQUIRED WORDS: OPTIONAL WORDS:

SET temperature low scale input
SET temperature high scale input
SET reference temperature
SET temperature low alarm
SET temperature high alarm
SET pressure low scale input
SET pressure high scale input
SET barometric pressure
SET pressure low alarm
SET pressure high alarm

SET k factor
SET k1 factor
SET z factor
SET gravity specific
SET c thermal expansion
SET heat specific

SET point
This command is followed by three numbers. The point number, the uncompensated flow (pulse or analog) and
then the K factor.

SET flow low scale input
SET flow high scale input
SET delta P high input
SET delta P low input
SET flow cutoff low
SET flow filter input
SET flow low alarm
SET flow high alarm

SET low output flow scale
SET high output flow scale
SET scale output flow digital factor pulse

SET id (See special section on SET ID; pg. 7)
SET baud (See special section on SET BAUD; pg. 7)
SET print interval

60

In addition to the optional words listed above, the words “to”, “of”, and “limit” are allowed in any phrase (in the
context of the SET command) and are always ignored.

SET TIME:

Reference: See Section 7
Format: : SET TIME [hh:mm] (CR)
Function: Sets the Real time clock in the instrument to time (hh:mm) where
hh indicates hours (00-23)
mm indicates minutes (00-59)
NOTE: 24 hour format must be used.

Example: SET TIME 12:42 (CR)

SET DATE:

Reference: See Section 7
Format: : SET DATE [mm/dd/yy] (CR)
Function: Sets the Real time clock on the instrument to date mm/dd/yy where
mm indicates month (1-12)
dd indicates day (1-31)
yy indicat es year (0-99)

Year numbers 88 through 99 indicate 1988 through 1999, 00 through 87 indicate 2000
through 2087

If desired, the year may be explicitly entered as 1992, for example.
Upon entry, the date is evaluated and rejected if illogical (Feb 29, 1989 would be rejected, for example)
Example: SET DATE 04.28.92 (CR)

SET ID:

Format:: SET ID [nn] (CR)
where nn is a number from 1-99
Function: Sets the device ID of the instrument to the number nn specified. If different from the

current ID, the instrument is immediately deselected. You must type Dnn to bring it back
online.

The unit is selected using a selection code beginning with the letter D followed immediately by a one or two digit
code in the range of 0-99. Further extraneous information entered on the line is ignored. The first serial command
sent to it should be Dnn to bring it online. Initially, and when the instrument is reinitialized, it defaults to Device #1.
The next return character sent to the control will enable it as indicated by the MFCnn prompt, where nn indicates
the device ID. When the instrument is powered up, it is deselected and must be enabled to communicate.

NOTE: Although there are up to 99 different ID numbers, this does not mean that 99 can be driven off one line.
The maximum number of units on a single RS-232 line is 20.

Example: SET ID 01 (CR)

61

SET BAUD

Format:: SET BAUD [nnnn] (CR)
Function: Sets the baud rate to the value specified in nnnn. nnnn may be 300, 1200, or 9600. The

baud rate is immediately set to the value specified.

NOTE: 300 baud may cause undesirable delays in communication.
Example: SET BAUD 1200 (CR)

SET EXCEPTION:

Format:: SET EXCEPTION [ON, OFF] (CR)
Function: Turns Exception Reporting ON or OFF.

Exception Reporting is a function that allows the operator to view different parameters that have recently gone into
alarm condition (See section on Exception Reporting in this chapter).

Example: SET EXCEPTION on (CR)

SET LIST:

Reference: See Section 8.2
Format:: SET LIST n n n n (CR)
Where n is the number of an item on the display list
Function: The SET LIST command is used to set up a display list which can be periodically printed at

a remote terminal or printer. The user would first type EXAMINE LIST to obtain a list of
available display items, and would then use the SET LIST command to enter them into a
printable list of items.

Example: MFC01 Examine List (CR)
[SELECT items from this list:]

[1] Time & Date
[2] Flow rate
[3] Totalizer
[4] Temperature
[5] Pressure
[6] Uncompensated Flow
[7] Raw Flow (Chan 3)
[8] Raw Temp. (Chan 1)
[9] Raw Press. (Chan 2)
[10] Analog Output

MFC01
NOTE: List will vary depending on Hardware and Computation Selected.
Then, the user selects time, flow rate, totalizer, and pressure by typing:

MFC01 SET LIST 1 2 3 5 (CR)
Then when the instrument is running and the PRINT INTERVAL is greater than 0.24999 minutes the instrument will

show:
11:55:52 Monday April 28, 1992
Flow Rate 10,000 SCFM

Terminal Responds: 4.00 mA

EXCEPTION REPORTING

Exception Reporting is used to send out a report whenever an alarm condition is present. As soon as an alarm
condition occurs, the unit sends out the following information over the RS-2 32 lin es :
The Unit ID number
The Time and Date
The Alarm Condition(s)

The unit will then send this information out, along with the print list selected, every print interval (of the print interval
is greater than 0.24999 minutes).

Each time an alarm condition is corrected, another exception report will be generated stating that the alarm
condition is no longer present.

NOTE: Even thought the alarm condition may have been corrected and the report sent out, the alarm relay will
NOT shut off until cleared through the front keypad or the RS-232 link.
