Operating Mode
The Flow Computer can be thought of as making a series of measurements of flow, temperature/ density sensors and then performing calculations to arrive at a result(s) which is then updated periodically on the display. The analog output, the pulse output, and the alarm relays are also updated. The cycle then repeats itself.
Step 1: Update the measurements of input signals-
Raw Input Measurements are made at each input using equations based on input signal type selected. The system notes the “out of range” input signal as an alarm condition.
Step 2: Compute the Flowing Fluid Parameters-The
temperature, viscosity, and density equations are computed as needed based on the flow equation and input usage selected by the user.
Step 3 : Compute the Volumetric Flow-Uncompensated
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 Conditions-In the case of a corrected liquid 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.
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

Specifications
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: 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 finally runs a task to update the various table entries associated with the front panel display and serial outputs.
Setup Mode
The setup mode is password protected by means of a numeric lock out code established by the user. In addition, a secret, manufacturer’s numeric unlock entry sequence is available.
The system also provides a minimum implemetation 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.
A Worksheet is provided to assist the user in setting up the instrument. In addition, a software program is available which runs on a PC using a RS-232 Serial connection to the Flow Computer. Illustrative examples may be down loaded in this manner.
The setup mode 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 affect offerings further down in the lists.
In the setup mode, 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.
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. A blank parameter will prevent the user from entering the run mode and a suitable warning message will be issued.
Also note that in the setup mode there 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.
Hint: It is possible to enter in a nominal constant
value for temperature or density, or analog flow 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 121 Series is the Test and Calibration Mode for the device. This mode provides a number of specialized utilities required for factory calibration, instrument checkout on start-up, and periodic calibration documentation.
A password is required to gain access to this specialized mode of operation. Normally

RS-232 Serial Port
The 121 Series has a general purpose RS-232 Port which may be used for any one of the following purposes:
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, a remote contact closure, or upon completion of a batch.
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 lists all the instrument setup parameters and usage for the current instrument configuration. In addition, the Audit trail information is presented along with a status report listing any observed malfunctions which have not been corrected.
The user initiates the printing of this report at a designated point in the menu by pressing the print key on the front panel.

General Operation
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 defined default values). The unit can be programmed to perform Ratemeter/Totalizer or Batching functions (see section 6.3, SELECT INSTRUMENT Submenu).
5.3 Ratemeter/TotalizerOperation
The Ratemeter/Totalizer mode is used primarily to monitor flowrate and accumulated total. The relays can be used to trigger flow, total, temperature or density alarms.
5.3.1 Password Protection for Rate/Total mode
After an Operator and/or Supervisor Password is entered in the setup mode (see section 6.3, SETUP PASSWORD submenu), the unit will be locked. The unit will prompt the user for the password when trying to perform the following functions:
Clear Total Clear Grand Total Enter Menu Edit Preset 1 Edit Preset 2
The Supervisor password should be reserved for supervisors. The Supervisor password will allow access to restricted areas of the Setup and Test menus.
5.3.2 Relay Operation in Rate/Total mode
Two relays are available for alarm outputs. The relays can be assigned to trip according to rate, total, temperature, density readings or general system alarms. The relays can be programmed for low or high alarms. Preset 1(RLY1) and Preset 2 (RLY2) are easily accessible by pressing the PRESET 1or PRESET 2 key on the front panel.
5.3.3 Pulse Output in Rate/Total mode
The isolated pulse output (open collector) is menu assignable to Volume Total, Corrected Volume Total or Mass Total. The pulse output duration can be set for 10mS (50 Hz max) or 100mS (5 Hz max). A pulse output scale factor (pulse value) can be set to scale the pulse output. The pulse output is ideal for connecting to remote totalizers or other devices such as a PLC. See section 1.3 for electrical specifications.
5.3.4 Analog Output in Rate/Total mode
The analog output is menu assignable to correspond to the Volume Rate, Corrected Volume Rate, Mass Rate, Temperature, Density, Volume Total, Corrected Volume Total or Mass Total. The analog output is ideal for "trend" tracking using strip chart recorders or other devices.
5.3.5 RS-232 Serial Port Operation in Rate/Total mode
The RS-232 serial port can be used for programming (using the Setup Disk) or for communicating to printers and computers in the Operating Mode (Run Mode).
PC Communications:
The Setup Disk also allows the user to query the unit for operating status such as Flow Rate, Flow Total, Temperature, Density, Presets, etc.

General Operation
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 6.3.20 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 defines 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, Configure).
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 Test menu (see section 8.2.3 PRINT SYSTEM SETUP).
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 flow control device (i.e. solenoid valve or pump). The flow sensor will send a signal to the unit and total accumulation will begin. When the Prewarn value (PRESET 2) is reached, Relay 2 will drop out (this is ideal for flow slow down). When the Batch amount (PRESET 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).
5.4.1 Batcher Configuration.
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.
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 flowrate. 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.
Auto Batch Restart
The Auto Batch Restart function allows the user to set an amount of time to automatically restart a batch after the completion of a batch (choose on or off).
121-000-350 © 2001 Max Machinery, Inc. Pg 17
Page 18
General Operation
Time Delay
The Time Delay for Auto Batch Restart functions as follows: When a batch is completed, the next batch will automatically start after the amount of time entered here. This time can be set from 1 to 99 seconds.
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 flow persists for more than the user entered time then the batch will be aborted. This prevents over flows due to faulty flow sensors and/or wiring.
Maximum Drain Time
The unit declares that a batch is “done” when the flow rate equals “0”. A flow 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 flow rate is “0” or the Maximum Drain Time has expired. The batch data will then be available for printing and datalogging.
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 flow) will energize for Slow Start and RLY 2 (fast flow) will energize after the Slow Start Quantity has been delivered. This helps reduce turbulence when filling an empty container.
START, RESET/START and STOP, STOP/RESET
When configuring 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.
5.4.2 Password Protection for Batcher Mode
After an Operator and/or Supervisor Password is entered in the setup mode (see section 6.3, SETUP PASS
WORD submenu), the unit will be locked. The unit will prompt the user for the password when trying to per
form the following functions:
Clear Grand Total
Enter Menu The Supervisor password should be reserved for supervisors. The Supervisor password will allow access to restricted areas of the Setup and Test menus. The passwords are factory set as follows:
Operator = 0
Supervisor = 2000
5.4.3 Relay Operation in Batcher mode
Two relays are available for alarm outputs. Preset 1 (RLY1) is reserved for batch amount, Preset 2 (RLY2) is reserved for prewarn. (see section 5.4 Batcher Operation for Relay 1 & Relay 2 functions) Preset 1 (RLY1) and Preset 2 (RLY2) are easily accessible by pressing the PRESET 1 or PRESET 2 key on the front panel.

RELAY NOTES & CONSIDERATIONS
1. Relay activation is based on the computed readings not the displayed value. Therefore the display damping factor will not affect the relay response time. The RELAY DELAY feature allows the user to enter a time delay for relay activation. This feature is very useful in applications where short over/under range conditions are not considered alarm conditions.
2. When INSTRUMENT TYPE is set to batcher, Relay 1 is reserved for PRESET and Relay 2 is
reserved for PREWARN. (the Prewarn value is relative to the Preset value. Input the
number of units that Relay 2 should “drop out” in advance of Relay 1.)
3. Setting the relays to NA (Not Assigned), will allow the relay activation to be controlled via the RS-232 Serial ports.

Principle Of Operation
7.1 General: General Operation
The 121 Series 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, density and viscosity. This information is then used to compute the Corrected Volume Flow or Mass Flow.
7.3 Flow Equations:
Input Flow Computation:
Linear or External SQRT Input Flow = [% input span • (flow FS - flow low scale)]+ flow low scale
Input Flow Computation:
General Case Tf = [% input span • (temp FS - Temp low scale)] + temp low scale
RTD Case Tf = f(measured input resistance)
Input Density Computation:
Temperature Transmitter density = reference density • (1 - Therm.Exp.Coef. • (Tf-Tref))
Density Transmitter density = [% input span • (density FS - density low scale)] + density low scale
Uncompensated Flow Computation:
Pulse Input; Average K-Factor Volume Flow = input frequency • time scale factor
Pulse Input; Linear Table Volume Flow = input frequency • time scale factor
Analog Input; Linear

7.4 Calculating the Expansion Factor Calculating
Expansion Factor
Two temperature-specific gravity pairs will be required to compute the temperature coefficient. The reference temperature is simply chosen by the user. Common reference temperatures are 60 F or 15 C. The reference temperature should be chosen so that it is in the application temperature range. (ex. application temperature range -10 to 120 F, reference temperature of 60 F chosen.) Enter the reference temperature you have chosen at this point. The reference specific gravity corresponds to the fluid SPECIFIC GRAVITY at the reference temperature chosen. You may convert the fluid density information to specific gravity if it is in units other than specific gravity. Use EQ1.
CAUTION: Since the expansion factor is based on a per degree change in temperature, the temperatures used in the following equations must match (Fahrenheit or Centigrade) the units used on the indicator display program­ming.
Expansion Factor Equations
EQ1.
Spec.Grav. = Density of Fluid / Density of Water
Given the reference temperature, reference specific gravity, a second temp. and a second Spec.Grav., the Expansion Factor (C Factor) can be computed as follows:
EQ2. Used for Liquid Mass and Corrected Volume Equations
C = 1 - √ (Spec.Grav.2 / Ref.Spec.Grav.) x 1,000,000
Temp.2 - Ref.Temp
Given the reference temperature, reference density, a second temp. and a second density, the Expansion Factor (C Factor) can be computed as follows:
Example: Diesel fuel (0.845@20˚C, 0.830@42˚)
C = 1 - √ 0.83/0.845 x 1,000,000 = 405.25
(42-20)
EQ3. Used for Liquid Mass and Corrected Volume Equations
C = 1 - √ (Dens.2 / Ref.Dens.) x 1,000,000
Temp.2 - Ref.Temp

7.6 Linearization Table
7.6.1 Linearization Table General Information
The Linearization Table is used when the flow input device gives a nonlinear input signal. The unit uses up to 16 different points, as entered by the operator, to form a curve for linearizing the input signal.
Notes:
1) A minimum of three points must be set up.
2) If "0" is entered for the frequency of any point other than point 1, the Flow Computer assumes there are no more points above the points that preceded them. The display will advance to the next setup prompt. Extrapolation is taken from the last two nonzero points.
3) If the input frequency is above the highest or below the lowest frequency programmed, the unit will use the last known point for the K factor in computing the resulting actual flow.
4) Frequencies or apparent flows should be entered in ascending order.
7.6.2 Linearization Table for Pulse Inputs
The linearization table for pulse inputs programming is quite simple when values of frequency and flow are known. The Flow Computer asks for 16 different frequencies (Freq) and 16 corresponding K factors (K). It then uses this data to determine what the actual flow is for any given input frequency. Usually the necessary data is provided with the flowmeter.
7.6.3 Linearization Table for Analog Inputs
The Linearization Table for Analog inputs programming is similar to the Pulse input setup. The Flow Computer asks for 16 different flow rates (apparent flow) and 16 corresponding Correction Factors. It then uses this data to determine what the Actual flow is for any given apparent input signal. Again, a minimum of three points must be set up.
Correction factor = Actual Flow
Apparent Input Flow
The same rules that applied for the Digital setup apply for the Analog setup as well. The Flow Computer prompts you for the Apparent input signal (APR) and a correction factor (CFr) to multiply it by to yield true actual flow.

9.1 RS-232 Port Description:
The Model 121 Series 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 (optional) Computer Communication Link Configuration by Computer Print System Setup Print Calibration/Malfunction History
9.2 Instrument Setup by PC’s over Serial Port
A Diskette program is provided with the Model 121 Series that enables the user to rapidly configure the unit using a Personal 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.
9.3 Operation of Serial Communication Port with Printers
The Model 121’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, a remote contact closure, or upon completion of a batch.
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. The user may specify a “next calibration date” for periodic maintenance. The unit will automatically remind the user that calibration is scheduled during instrument power up and in some printed documents after that date.

11. Flow Computer Setup Software
The Model 121 setup program provides for configuring, monitoring and controlling the indicator.
Sample applications are stored in disk files. The setup program calls these Templates. You can store the setup
from the program’s memory to either the Model 121 (Downloading the file) or to a disk file (Saving the file) for
later usage. Similarly you can load the setup in program memory from either a disk file (Opening a file) or from
the Model 121 unit (Uploading a file). The program can monitor outputs from the unit while it is running. The program can reset alarms and totalizers. For assistance there are mini-helps at the bottom of each screen in the program. There is also context sensitive
help available for each screen accessible by pressing the F1 key.
11.1 System Requirements:
IBM PC or compatible with 386 or higher class microprocessor
4 MB RAM 3 MB free disk space VGA or higher color monitor at 640 x 480 Microsoft® Windows™ 3.1 or 3.11 or Windows 95™
Communication Port - RS-232
RS-232 Cable
11.2 Cable and Wiring Requirements:
The serial communication port on your PC is either a 25 pin or 9 pin connector. No cabling is supplied with the setup software. A cable must be purchased separately or made by the user. It is recommended to purchase a modem cable which matches the available communication port on you PC and a 9 pin male connection for the Model 121 serial port.
11.3 Installation for Windows™ 3.1 or 3.11
The Setup Software includes an installation program which copies the software to your hard drive. Insert Setup Disk 1 in a floppy drive. In the Program Manager, click File, and then select Run.

Pg 56 121-000-350 © 2001 Max Machinery, Inc.
Page 57
11.5 File Tab
The File Tab has three sections. Any of the options on this tab can also be accessed from the File submenu. The Template Section provides for opening and saving templates. The Save and Save As buttons provide the
standard Windows functionality for dealing with files. The Load button is used to open existing templates. There are two additional menu items available only from the File menu: Create new file and Templates. The Create new file, option allows for creating custom templates using the existing template in memory as the
starting point. Assign a new name for this template. The template will be saved under this new name.
The Template option will bring up a list of predefined templates that can be loaded into the program. These predefined templates are useful as a starting point when defining custom templates.
A typical scenario using the setup program would be the following:
• Open up a predefined template from the supplied list
• Choose ‘Save As’ to save this to a new file name
• Proceed to customize the template by making any changes that are needed
• Save the template to disk (if you want to reuse this template)
• Download the template to an attached unit.
The Communications with Model 121 Section allows the user to upload a template file from the unit, download the program’s current template to the unit or Compare the program’s current template with the unit.
The Print (report) Section allows the user to:
1. Configure the current WindowsTMprinter through the Select Printer option.
2. Print a Maintenance Report through the PC's printer using the Print Maintenance option.
3. Print the current template through the PC's printer using Print Setup option.
11.6 Setup Tab

Batch Count Mode specifies the user preference for count direction. The "Up" selection begins with a value of "0" and counts up until the batch size is reached. The "Down" selection begins with a value equal to the desired batch size and counts down to "0".
Batch Overrun
The Model 121 offers a batch overrun compensation routine. If batch overrun occurs due to slow valve response time, the unit will compensate for the overrun amount on the next batch. This feature can be disabled if desired.
Batcher
An instrument which controls the dispensing of desired batch amounts. Liquid batching systems are usually comprised of a batch controller (batcher), flowmeter and control valve. The batcher opens and closes the valve through the use of relays and measures the amounts of liquid being dispensed via the flowmeter.
Baud Rate
The speed of serial communication transmissions, expressed in bits per second.
C-Factor (Fluid Expansion Factor)
A parameter in a flow equation which is used to describe the relationship between density or volume and temperature changes.

12. Glossary Of Terms (Continued)
means of controlling the information flow between two pieces of equipment to prevent the sending device from transmitting
information at a rate faster than what can be accepted by the receiver.
Hysteresis
The relay hysteresis is a "dead band" setting which allows the relay to remain energized for a given amount below the setpoint. This is used to prevent relay chatter when the process value is near the setpoint value. Example: If the Preset is set at 100, and the hysteresis is set at 10, the relay will energize when the rate, temp or dens. reaches 100, the relay will remain energized until the reading falls below 90.
Input Termination
Input signal lines on digital inputs often require pullup or pulldown resistor configurations to operate properly with different sensor configurations. The Model 121 contains such resistors and may be enabled via the setup menu.
Inhibit Totalizer
"Inhibit Total" is a Control Input 1 setting that is used to stop the totalization. If enabled, a voltage level on control input 1 will inhibit the total as long as the voltage is present. This feature is useful during meter proving and in applications that provide a sensor to signal the flow computer when fluid is present.
K-Factor
A scaling factor derived from the pulses produced by a flowmeter output, expressed in pulses per unit (i.e. pulses/gallon)
Limit Setpoint

Linear Flowmeter
A flow measurement device whose output is proportional to flow.
Linearization
The mathematical correction of a nonlinear device. The Model 121 uses a linearization Table which is made up of input/output values and makes interpolations of the table to arrive at a "linearized" measurement.
LinTbl
Abbreviation for Linearization Table.
Low Flow Cutoff
A value set at which any flow measurements read below this value will be ignored.
Low Pass Filter
A low pass filter passes low input frequencies while blocking high frequencies. In the Model 121, this is the maximum input count speed to be encountered in an application. It is expressed in counts per second (Hz).
Mass Flow
Mass Flow is inferred by the volumetric flow and density (or implied density) of a fluid.
Flow Signal Timeout
Flow Equation
Follow, Alarm
Function Key
Handshake
The Flow Signal Timeout allows the user to enter a timeout of 0 to 99 seconds. If a batch is “Filling” and zero flow persists for more than the user entered time then the batch will be aborted. This prevents over flows due to faulty flow sensors and/or wiring.
A flow control expression or algorithm describing a mathematical equation to be solved by a flow computer in the desired application.
Alarm relays which are non latching and whose output state is based solely on the comparison of the current process value and the alarm setpoint (trip point).
A key on a push-button panel or keyboard (whose function is described by the key label) used to perform an instrument function or special routine.

Preset
A set point used to trigger the relay outputs of the 121 Series.
Print Interval
The print interval allows the 121 Series to transmit information to the serial port at selectable time intervals.
Private Code
An operator password code which authorizes changes to the setup of the instrument but blocks access to the Service/Calibration/Test mode. The private code also blocks the clearing of the Grand Total.
Process Parameters
Any sensor information which has been scaled to engineering units including Flow, Temperature and Density.
Pulldown (Input Termination)
The termination of an input at which the input is pulled down to ground through a resistor. Inputs that are terminated by this method need to be driven high with a positive voltage pulse.
Pullup (Input Termination)
The termination of an input at which the input is pulled up to a positive voltage through a resistor. Inputs that are terminated by this method need to be pulled low with a sinking current or contact to ground .
Pulse Output
The pulse output of the 121 Series is available for remote accumulation of the total or sent to peripheral devices, such as a PLC. The output can be scaled using the Pulse Output Scaling Constant.
Quad
Abbreviation for Quadrature. Quadrature signals are used for direction control. Two flowmeter signals are output with a 90° phase shift. The counter counts UP when channel Aprecedes channel B, and counts DOWN when Channel A lags Channel B.
Quick Setup
A utility that provides for rapid configuration of an instrument. The Model 121 quick setup provides the following:
1) Prompts the user for only critical information.
2) Automatically sets specifications to common uses. After following the Quick Setup procedure, the unit will be operational to perform the basic measurement. The setup can be further customized using the setup menus.
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.
Maximum Drain Time
The unit declares that a batch is “done” when the flow rate equals “0”. A flow 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 flow rate is “0” or the Maximum Drain Time has expired. The batch data will then be available for printing and datalogging
