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

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

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.

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.

RS-232 Serial Port Operation of RS-232 Serial Port with Printers

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).

RS-485 Serial Port Operation

Pause Computations Prompt

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. Please review the following key usage summary before attempting to setup the instrument.

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 =

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 “†”.

Flow Equations

7.3.1 Flow Input Computation

Note concerning Fluid Information

The user will be prompted for Fluid Information during the setup of the instrument. SeeAppendix A for the properties of several common fluids.

7.3 Flow Equations:

Flow Input Computation:

Linear

Input Flow = [% input span • (flow FS - flow low scale)]+ flow low scale

Square Law without External SQRT Extractor

delta P = [(% input span) • ( flow FS - flow low scale)] + flow low scale

Square Law with External SQRT Extractor

delta P = [(% input span)2 • ( flow FS - flow low scale)] + flow low scale

NOTE:For stacked differential pressure option, the appropriate input sensor signal is used in calculations at all times to maximize accuracy.
