Operating Mode

The Flow Computer can be thought of as making a series of measurements of ow, temperature/density sensors and then performing calculations to arrive at a result(s) which is then updated periodically on the display. The analog output, the pulse output, and the alarm relays are also updated. The cycle then repeats itself.

Step 1: Update the measurements of input

signalsRaw Input Measurements are made at each input using equations based on input signal type selected. The system notes the “out of range” input signal as an alarm condition.

Step 2: Compute the Flowing Fluid Parameters-

The temperature, viscosity, and density equations are computed as needed based on the ow equation and input usage selected by the user.

Step 3 : Compute the Volumetric Flow-

Uncompensated ow is the term given to the ow in volume units. The value is computed based on the owmeter input type selected and augmented by any performance enhancing linearization that has been specied by the user.

Step 4: Compute the Corrected Volume Flow at Reference Conditions-

In the case of a corrected liquid volume ow calculation, the corrected volume ow is computed as required by the selected compensation equation.

Step 5 : Compute the Mass Flow-

All required information is now available to compute the mass ow rate as volume ow times density.

Step 6: Check Flow Alarms-

The ow alarm functions have been assigned to one of the above ow rates during the setup of the instrument. A comparison is now made by comparing the current ow rates against the specied hi and low limits.

Step 7: Compute the Analog Output-

This designated ow rate value is now used to compute the analog output.

Step 8: Compute the Flow Totals by Summation-

A ow total increment is computed for each ow rate. This increment is computed by multiplying the respective ow rate by a time base scaler and then summing. The totalizer format also includes provisions for total rollover.

Step 9: Total Preset Comparisons-

The total associated with a preset function is then compared against the corresponding preset value and any required control actions taken.

Step 10: Pulse Output Service-

The pulse output is next updated by scaling the total increment which has just been determined by the pulse output scaler and summing it to any residual pulse output amount.

Step 11: Update Display and Printer Output-

The instrument nally runs a task to update the various table entries associated with the front panel display and serial outputs.

SUPERtrol-I Flow Computer

Setup Mode

The setup mode is password protected by means of a numeric lock out code established by the user. In addition, a secret, manufacturers numeric unlock entry sequence is available.

The system also provides a minimum implementation of an “audit trail” which tracks signicant setup changes to the unit. This feature is increasingly being found of benet to users or simply required by Weights and Measurement Ofcials in systems used in commerce, trade, or “custody transfer” applications.

A software program is available which runs on a PC using a RS-232 Serial for connection to the Flow Computer. Illustrative examples may be down loaded in this manner.

The setup mode has numerous subgrouping of parameters needed for ow calculations. There is a well conceived hierarchy to the setup parameter list. Selections made at the beginning of the setup affect offerings further down in the lists.

In the setup mode, the ow computer activates the correct setup variables based on the instrument conguration, the ow equation, and the hardware selections made for the compensation transmitter type, the flow transmitter type, and meter enhancements (linearization) options selected. All required setup parameters are enabled. All setup parameters not required are suppressed.

A help line prompt is provided for each entry. In addition a help message is available which may be accessed by depressing the “HELP” key.

In the setup mode selections, several parameters are required to be input by the operator since these parameters are blank when the unit is received. The user will be prompted for these necessary values for his application.

Also note that in the setup mode are parameter selections which have preassigned industry standard values. The unit will assume these values unless they are modied by the user.

Most of the process input variables have available a “default” or emergency value which must be entered. These are the values that the unit assumes when a malfunction is determined to have occurred on the corresponding input.

It is possible to enter in a nominal constant value for temperature or density, or analog ow inputs by placing the desired nominal value into both the lo and hi values. This is also a convenience when performing bench top tests without simulators.

Maintenance Mode:

The Maintenance Mode of the Flow Computer is the Test and Calibration Mode for the device. This mode provides a number of specialized utilities required for factory calibration, instrument checkout on startup, and periodic calibration documentation.

A password is required to gain access to this specialized mode of operation. Normally quality, calibration, and maintenance personnel will nd this mode of operation very useful. It is also useful for factory testing.

Many of these tests may be used during start-up of a new system. Inputs signals may be read, and output signals may be exercised to verify the electrical interconnects before the entire system is put on line.

The following action items may be performed in the Maintenance Mode:

Print Calibration/Maintenance Report Examine Audit Trail Perform Keypad Checkout Perform Display Checkout Perform Pulse Input Checkout Perform Pulse Output Checkout Perform Control Input Checkout Perform Relay Output Checkout Perform Analog Input Checkout Perform Analog Output Checkout Calibrate Analog Inputs using the Learn Feature Calibrate Analog Output using the Learn Feature Battery Check

Note that a calibration of the analog input/output will advance the audit trail counters since it effects the accuracy of the system.

RS-232 Serial Port

The Flow Computer has a general purpose RS-232 Port which may be used for any one of the following purposes:

Transaction Printing Data Logging Internal Datalog Dumps Remote Metering by Modem (optional) Computer Communication Link Conguration by Computer Print System Setup Print Calibration/Malfunction History Remote Control

Instrument Setup by PC’s over Serial Port

A Diskette program is provided with the Flow Computer that enables the user to rapidly congure the Flow Computer using an Personnel Computer. Included on the diskette are common instrument applications which may be used as a starting point for your application. This permits the user to have an excellent starting point and helps speed the user through the instrument setup.

SUPERtrol-I Flow Computer

Operation of Serial Communication Port with Printers

Flow Computer’s RS-232 channel supports a number of operating modes. One of these modes is intended to support operation with a printer in metering applications requiring transaction printing, data logging and/or printing of calibration and maintenance reports.

For transaction printing, the user denes the items to be included in the printed document. The user can also select what initiates the transaction print generated as part of the setup of the instrument. The transaction document may be initiated via a front panel key depression, a remote contact closure, or upon completion of a batch.

In data logging, the user denes the items to be included in each data log as a print list. The user can also select when or how often he wishes a data log to be made. This is done during the setup of the instrument as either a time of day or as a time interval between logging.

The system setup and maintenance report lists all the instrument setup parameters and usage for the current instrument conguration. In addition, the Audit trail information is presented along with a status report listing any observed malfunctions which have not been corrected.

Operation of Serial Port with Modems (optional)

The Flow Computer RS-232 channel supports a number of operating modes. One of these modes is intended to support operation with a modem in remote metering applications.

An external modem is intentionally being used with the Flow Computer. This permits use with the variety of modem standards worldwide while avoiding the specialized approvals required for equipment that is deemed to fall under the category of telecommunication equipment.

In the modem mode, the Flow Computer is assumed to be operating in a remote metering role. The Flow Computer will support key items in the Hayes Compatible “AT” Command Set. In this role, the Flow Computer will have the following special abilities:

0. Monitor the modem status as a task of the

system

1. Instruct the modem to answer an incoming call

ATA

2. Respond to the calling modem at a compatible

baud rate and protocol

3. Perform error checking in conjunction with the

modem

4. Monitor the status of the carrier

5. Terminate the telephone connection in event the

connection is lost.

The user initiates the printing of this report at a designated point in the menu by pressing the print key on the front panel.

In addition, the Flow Computer will be capable of initiating a call to a designed telephone number in the event of a metering malfunction.

5.2 General Operation

The unit can display: Rate, Total, Grand Total, Temperature, Density, Presets and Time of Day. The Temperature and/or Density can be displayed even if you are using the Volumetric Flow Equation (a Temperature or Density sensor must be installed). The unit can perform Mass or Corrected Volume equations using a temperature or density sensor (these equations can be computed without Temp/ Dens sensors by using user dened default values). The unit can be programmed to perform Ratemeter/Totalizer or Batching functions (see section 6.3, SELECT INSTRUMENT Submenu).

5.3 Ratemeter/Totalizer Operation

The Ratemeter/Totalizer mode is used primarily to monitor owrate and accumulated total. The relays can be used to trigger ow, total, temperature or density alarms.

5.3.1 Password Protection for Rate/Total mode

After an Operator and/or Supervisor Password is entered in the setup mode (see section 6.3, SETUP PASSWORD submenu), the unit will be locked. The unit will prompt the user for the password when trying to perform the following functions:

A pulse output scale factor (pulse value) can be set to scale the pulse output. The pulse output is ideal for connecting to remote totalizers or other devices such as a PLC. See section 1.3 for electrical specications.

Analog Output

(Rate/Total mode)

5.3.4 Analog Output in Rate/Total mode

The analog output is menu assignable to correspond to the Volume Rate, Corrected Volume Rate, Mass Rate, Temperature, Density, Volume Total, Corrected Volume Total or Mass Total. The analog output is ideal for "trend" tracking using strip chart recorders or other devices.

SUPERtrol-I Flow Computer

RS-232 Serial Port

(Rate/Total mode)

5.3.5 RS-232 Serial Port Operation in Rate/Total mode

The RS-232 serial port can be used for programming (using the Setup Disk) or for communicating to printers and computers in the Operating Mode (Run Mode).

PC Communications:

The Setup Disk also allows the user to query the unit for operating status such as Flow Rate, Flow Total, Temperature, Density, Presets, etc.

Operation of RS-232 Serial Port with Printers:

Transaction Printing For transaction printing, the user denes the items to be included in the printed document (see section 6.3.20 SET DATA OUTPUT, Select_list). The transaction document can be initiated by pressing the PRINT key or by a remote contact closure.

Data Logging In data logging, the user denes the items to be included in each data log (see section 6.3.20 SET PRINTER OUTPUT, Select_list). The user can also select when (time of day) or how often (print interval) the data log is to be made (see section 6.3.19 SET PRINTER OUTPUT, Congure).

System Setup and Maintenance Report The system setup and maintenance report lists all of the instrument setup parameters and usage for the current instrument conguration. The audit trail information and a status report is also printed. This report is initiated in the Test menu (see section 8.2.3 PRINT SYSTEM SETUP).

RS-485 Serial Port

(Rate/Total mode)

5.3.6 RS-485 Serial Port (optional)

RS-485 Port Description:

The optional RS-485 card utilizes Modbus RTU protocol to access a variety of process parameters and totalizers. The Relays can be controlled via Modbus. In addition, action routines can be executed. For further information, contact factory and request RS-485 Protocol manual.

Operation of Serial Communication Port with PC

The ow computer's RS-485 channel supports a number of Modbus RTU commands. Modbus RTU drivers are available from third party sources for a variety of Man Machine Interface software for IBM compatible PC's.

The user reads and writes information from/to the RS-485 using the Modbus RTU commands. The Flow Computer then responds to these information and command requests.

Process variables and totalizers are read in register pairs in oating point format. Time and date are read as a series of integer register values. Alarms are individually read as coils. Action routines are initiated by writing to coils.

SUPERtrol-I Flow Computer

5.4 Batcher Operation

The Batcher mode is used primarily to control batches. The main difference between the Batch mode and Rate/Total mode is the relay operation. The Batch mode allows the operator to "START" the unit via the front panel or remote input. Once started, the relays (RLY1 & RLY2) will energize and send power to a ow control device (i.e. solenoid valve or pump). The ow sensor will send a signal to the unit and total accumulation will begin. When the Prewarn value (PRE 2) is reached, Relay 2 will drop out (this is ideal for ow slow down). When the Batch amount (PRE 1) is reached, Relay 1 will drop out and the Batch is complete.

Several messages will be displayed during normal batch operation (i.e. Batch Fill, Batch Stopped). The keypad is disabled for the duration of these timed messages (approx. 2 sec).

Batcher Conguration

5.4.1 Batcher Conguration.

When the unit is programmed for batch mode, several batch operation choices are available. These choices include: Up or Down Counting, Maximum Batch Preset, Batch Overrun Compensation, Auto Batch Restart, Time Delay, Flow Signal Timeout, Maximum Drain Time, Slow Start Quantity, Start or Reset/Start, and Stop or Stop/Reset.

Standard Preset or EZ Preset

Use Standard Preset for applications in which the batch amount does not change frequently. Use EZ Preset in applications in which the batch amounts change frequently. The EZ Preset mode was designed to enter presets with minimum key strokes.

Batch Count Mode

The Batch Count Mode allows the user to choose whether the unit will batch up to a preset value or batch down from a preset value to zero.

Maximum Batch Preset

The Maximum Batch Preset allows the user to program the Maximum Batch value allowed to be entered by the operator. If an operator should try to program a batch higher then this value, the unit will not allow the value to be entered and will prompt the user with an error message saying that the Maximum Batch Preset has been exceeded.

Batch Overrun

The Batch Overrun is used for batch applications that have slow responding valves and a consistent batching owrate. When the Batch Overrun is set, the unit will compensate for batch overruns by computing an averaged overrun value from the last four batches. This average is used to internally adjust the batch setpoint to minimize overrun.

Flow Signal Timeout

The Flow Signal Timeout allows the user to enter a timeout of 0 to 99 seconds. If a batch is “Filling” and zero ow persists for more than the user entered time then the batch will be aborted. This prevents over ows due to faulty ow sensors and/or wiring.

Maximum Drain Time

The unit declares that a batch is “done” when the ow rate equals “0”. A ow rate may be present long after the Preset Relay de-energizes due to slow reacting valves or leaky valves. The Maximum Drain Time allows the user to enter an amount of time (0 to 99 seconds) to wait before declaring “Batch Done”. After the Preset Batch quantity is reached, the unit will declare “Batch Done” when the ow rate is “0” or the Maximum Drain Time has expired. The batch data will then be available for printing and datalogging.

SUPERtrol-I Flow Computer

Slow Start Quantity

The Slow Start Quantity is a function that allows an amount to be entered for a Slow Start up. This function requires two stage valve control. RLY 1 (slow ow) will energize for Slow Start and RLY 2 (fast ow) will energize after the Slow Start Quantity has been delivered. This helps reduce turbulence when lling an empty container.

START, RESET/START and STOP, STOP/RESET

When conguring the control inputs, Control Input1 can be set for START or RESET/START. When set for START, the unit will start batching when a signal is applied to Control Input1 or the front panel Start key is pressed. A separate Reset signal must be used to clear the previous batch total. When set for RESET/ START, the unit will automatically reset then start when a signal is applied to Control Input1 or the front panel Start key is pressed (provided that the pervious batch was completed). If a previous batch was stopped during a batch cycle, the unit will Start from where it was stopped. Control Input 2 can be set for STOP or STOP/RESET. When set for STOP, the unit will stop batching when a signal is applied to Control Input 2 or the front panel Stop key is pressed. A separate Reset signal must be used to clear the batch total. When set for STOP/RESET, a running batch will stop when a signal is applied to Control Input 2 or the front panel Stop key is pressed. If the unit is Stopped or after a completed batch, the unit will reset when a signal is applied to Control Input 2 or the front panel Stop key is pressed. NOTE: Applying a voltage level to Control Input 2 will inhibit all Start inputs in

either mode.
