Operating Mode
The LEVELtrol-II can be thought of as making a series of measurements of level, 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 and density equations are computed as needed based on the instrument equations and input usage selected by the user.
Step 3 : Compute the Tank Level
The value is computed based on the level sensor input type selected and by installation details on the tank.
Step 4: Compute the Uncorrected Tank Volume
Compute the uncorrected tank volume from the tank level measurement and known geometry of the tank.
Step 5: Compute the Corrected Tank Volume at
Reference Conditions or Mass in tank.
Step 6: Check Alarms
The alarm functions have been assigned to one of the above during the setup of the instrument. A comparison is now made by comparing the current value against the specified hi and low limits.
Step 7: Compute the Analog Output
This designated process value is now used to compute the analog output.
Step 8: 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 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.

LEVELtrol-II Installation & Operating Instructions
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 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 (optional) which runs on a PC using a RS­232 Serial for connection to the instrument. Illustrative examples may be down loaded in this manner.
The setup mode has numerous subgrouping of parameters needed for the instrument functions. There is a well conceived hierarchy to the setup parameter list. Selections made at the beginning of the setup hide unnecessary items further down in the lists.
In the setup mode, the instrument activates the correct setup variables based on the instrument configuration, the equations, and the hardware selections made for the compensation transmitter type, the level transmitter type, and any enhancement 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.
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 modified by the user.
Maintenance Mode:
The Maintenance Mode of the LEVELtrol-II 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 Supervisor or Manufacturers password is required to gain access to this specialized mode of operation. Start-up, quality, calibration, and maintenance personnel will find 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 Examine Error History Perform Keypad Checkout Perform Display 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 Voltage Test Print Datalogger Contents
Note that a calibration of the analog input/output will advance the audit trail counters since it effects the accuracy of the system.
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 level 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.

LEVELtrol-II Installation & Operating Instructions
RS-232 Serial Port
The LEVELtrol-II 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
Instrument Setup by PC’s over Serial Port
A Diskette program is optionally available with the instrument that enables the user to rapidly configure the LEVELtrol-II 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.
Operation of Serial Communication Port with Printers
LEVELtrol-II’s RS-232 channel supports a number of operating modes. One of these modes is intended to support operation with a printer in applications requiring transaction printing, data logging and/or printing of calibration and maintenance reports.
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.
Operation of Serial Port with Modems (optional)
The LEVELtrol-II 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.
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.

Batcher Operation
Batcher Configuration

5.4 Batcher Operation

The Batcher mode is used primarily to dispense batches of fluid based on changes in tank volume as indicated by tank level. The main difference between the Batch mode and Level/Total mode is the relay operation. The Batch mode allows the operator to "START" the batch transfer 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 level sensor will send a signal to the unit and total comparisons will begin. When the Prewarn value (PRE 2) is reached, Relay 2 will drop out (this is ideal for flow 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).

5.4.1 Batcher Configuration.

When the unit is programmed for the batch mode, several batch operation choices are available. These choices include: Up or Down Counting, Batch Into or Out of the Tank, Batch Overrun Correction feature, Start or Reset/Start, and Stop or Stop/Reset.
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.
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 previous batch was completed). If a previous batch was stopped during a batch cycle, the unit will Restart 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 or override
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 PASSWORD submenu), the unit will be locked. The unit will prompt the user for the password when trying to enter the menu. The unit will also prompt the user to enter the password if this access has been limited.
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
A control input can also be configured as a jumper hardware lockout.

5.4.3 Relay Operation in Batcher mode

Four relays are available for batch control and/or alarm outputs. Preset 1 (RLY1) is reserved for batch amount, Preset 2 (RLY2) is usually 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 PRE 1 or PRE 2 key on the front panel. Preset 3 and Preset 4 are accessible only through the setup menu. Relays 3 and 4 can be assigned to trip according to level, temperature, density, overrun or alarm. When level, temperature or density is selected the relays can be programmed as low or high alarms. Overrun can be used to detect minor leakage around valves in some applications.
Pulse Output
(Batch mode)
NOTE: Choose relay operations that will fail safe for your process. Also
use suitable safety interlocks (level switches) to prevent overfilling containers.

5.4.4 Pulse Output in Batcher mode

The isolated pulse output (open collector) is assigned to produce pulses on changing Volume, Corrected Volume or Mass as indicated by the pulse output usage and the compensation equation selected. The pulse output duration can be set for 10mS (100Hz max) or 100mS (10Hz 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. It may be used to keep track of deliveries, the amount sent to/from a tank or for a combination of these. See section
1.3 for electrical specifications.

7. Principle Of Operation
General Operation
Determining the Liquid Quantity for Various Tank Geometries
7.1 General Operation
The determination of the level and the amount of material in a tank is a commonly needed industrial measurement. In other applications it is desired to dispense liquid from one container to another. This instrument is intended to satisfy these needs.
A variety of displays, analog outputs, pulse outputs, alarms, and communications ports are provided to suit the various application needs which might be encountered.

7.2 Determining the liquid quantity for various Tank Geometries

Various tank geometries are used in industry as containers for liquids. These tank geometries may be classified as vertical cylindrical, horizontal cylindrical, or spherical. Many “calibrated” tanks come with a “strapping chart” which equates the volume in the tank for various liquid level measurements.
This instrument permits the user to either enter his tank shape and dimensions or strapping table. The unit then computes the volume in the tank for the measured liquid level based on mathematical equations solved by the instrument.
Determining Liquid Level
Tanks often have a discharge location which is somewhat above the base of the tank so that the tank can never be fully drained. The quantity of fluid below the discharge point is sometimes called a “reserve” amount. The instrument computes both the total amount and the available amount from the discharge location information entered by the user.

7.3 Determining Liquid Level

A liquid level measurement is required in order to compute the quantity in a tank.
There are a wide variety of liquid level measurement techniques to choose from. Among the most common measurement techniques are:
a. hydrostatic pressure measurement b. ultrasonic level measurement
The equations necessary to compute the liquid level are different for the two techniques. This instrument uses the correct equation for the level sensor type you have chosen. The level calculations also include adjustments for the location of the sensor above the base of the tank.
7.4 Corrections for density in hydrostatic pressure based level measurements
The hydrostatic pressure measured at the base of a tank is a function of the liquid level and the density of the fluid.
The LEVELtrol-II provides for the connection of a compensated input, a temperature or density transmitter, which will enable accurate determination of the liquid level in the tank. Stored fluid properties are used to infer the density from a temperature measurement.
38
Page 45
LEVELtrol-II Installation & Operating Instructions

7.5 Computation of Corrected Volume in Tank and Mass in Tank

The mass in the tank can be computed if the volume in the tank and the density are known. This instrument has menu selections which permit the user to compute and view the quantity in the tank in mass units.
Corrected Volume is the equivalent volume the liquid would occupy at some reference condition. This instrument also provides menu selections which permit the user to compute and view the quantity in the tank in corrected volume units. This is often useful in determination of volume in the tank for petroleum quantities when it is desired to know the volume the liquid would occupy at 60 F. (Remember that when the temperature of the material is changing and the actual volume of the material in the tank is changing with that temperature based on the expansion factor for the liquid.).
LEVELtrol II Equations Summary
Level_Sensor = % • (Level_fs-Level_zero) + Level_zero Temperature = % • (Tfs - Tzero) + Tzero Density = % • (Dfs - Dzero) + Dzero Density = Dref • (1 - c•1e-6 • (Tf - Tref))

7.6 Calculating the Expansion Factor For a Fluid

Calculating Expansion Factor
The liquid density is a function of the flowing temperature for many fluids. This unit solves an equation which represents this physical property of the fluid.
The information which the unit uses to describe the fluid is entered by the user in the following variables: Reference Temperature, Reference Density, Expansion Factor These parameters can be derived from fluid information available in one or more of the following forms:
Fluid Specific Gravity vs. Temp. Table Specific Gravity vs. Temp. Graph Fluid Density vs. Temp. Table
Fluid Density vs. Temp. Graph Begin by obtaining one of the fluid properties for the fluid you are using from available manufacturers information or Engineering Handbooks. In some cases this information is listed on the Material Safety Data Sheet for the fluid. Two temperature-density pairs will be required to compute the temperature coef ficient. The reference temperature is simply chosen by the user. Common reference temperatures are 60° F or 15° C. However, for cryogenic fluids, the normal boiling point may also be used. In some cases the fluid data may list properties at 100° F, this temperature may also be used as the reference temperature. The reference temperature should be chosen so that it is in the application temperature range. i.e. 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 density corresponds to the fluid density at the reference temperature chosen. Enter this information in the units that are prompted for by the unit.

11.7 View Tab

LEVELtrol-II Installation & Operating Instructions
The View Tab screen allows for viewing selected group items on the PC in a similar format as shown on the unit display. Data from the following groups can be viewed in the List of Values section:
Process Parameters (i.e. level, temperature) Totalizers (i.e. total, grand total)
The setup software assumes the current setup has been uploaded from the instrument into the PC. It is important that the setup program and the LEVELtrol-II unit are using the same setup information at all times or the information requests will be inconsistent. It is best to upload or download the setup before using this feature.
To start the viewer, first check the boxes of items to view and then click the start button. The data will appear in the appropriate sections and will be continuously updated. The refresh rate is dependent on the number of items that are being viewed and the baud rate of the connection. Data in the List of Values section can be collapsed by clicking on the ‘minus’ sign in front of the group title. The data can be expanded by clicking on the ‘plus’ sign in front of the group title. If a group is collapsed and data in the group changes on refresh, the group will automatically expand. Changing the view items requires stopping the current viewing, checking the new selections and then restarting the viewer.
If communication errors occur while reading data from the LEVELtrol-II device, the word ‘Error’ will appear in place of the actual value. If the connection to the LEVELtrol-II is lost, the viewer will time out with a message saying the device is not responding.
The viewer will attempt to communicate with the LEVELtrol-II device matching the device ID set in the communications screen. If you are having trouble establishing communication, compare settings for the PC and the instrument. Also verify the connections between the PC and instrument.

12. Glossary Of Terms (Continued)
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 relay is assigned to temperature and the Preset is set at 100, and the hysteresis is set at 10, the relay will energize when the temperature reaches 100, the relay will remain energized until the reading falls below 90.
Instrument Type
A description of the basic instrument function. (i.e. Level/Total or Batcher)
Key Lock
A hard wire jumper which blocks access to the instrument setup and test mode.
LCD
Abbreviation for: Liquid Crystal Display
Level Sensor Type
The basic measurement principle for the level sensor.
Limit Setpoint
An alarm trip point setting which specifies the value or magnitude of a process parameter necessary to activate an alarm indicator or control relay.

The permissions given to users without password prompts.
Operator Password
An operator password code which authorizes changes to the setup of the instrument but blocks access to the Service/Calibration/Test mode.
Parity
A method for detecting errors in transmissions of serial communications data.
Preset
A set point used to trigger the relay outputs of the LEVELtrol-II.
Print Interval
The print interval allows the LEVELtrol-II to transmit information to the serial port at selectable time intervals.

Pulse Output
The pulse output of the LEVELtrol-II is available for remote accumulation of the delivery totals or batch totals into or out of the tank. The output can be scaled using the Pulse Output Scaling Constant.
Level Averaging Filter
The level averaging filter is used to stabilize fluctuating level displays. Higher settings provide more averaging for a more stable display. Derived from the equation: (OLD DATA x "Avg. Filter" + NEW DATA)
("Avg. Filter" + 1)
Ref. Dens.
Abbreviation for Reference Density. This is the fluid density at reference temperature.
Ref. Temp.
Abbreviation for Reference Temperature. This represents the base or reference condition to which corrected total will be computed.
Reset/Start Control Input
In a batching system, a single operator activation of the START key or Control Input 1 will reset the total then start the batch process.
Sensor Location
The distance above the base of the tank at which the sensor is installed.
Stop/Reset Control Input
In a batching system, a single operator activation of the STOP key or Control Input 2 will stop the batch process then reset the total.
Strapping Table

13. Diagnosis and Troubleshooting

13.1 Response of LEVELtrol-II on Error or Alarm:

Error and warning indications which occur during operation are indicated in the RUN mode alternately with the measured values. The instrument has three types of error:
TYPE OF ERROR DESCRIPTION
Sensor/Process Alarms Errors detected due to sensor
Self Test Errors Errors detected during self test.
failure or process alarm conditions
System Alarms Errors detected due to system
failure
Some alarms are self clearing. Other alarms require the user to acknowledge and clear the alarm. Press the ENTER button to acknowledged and clear alarms. Alarms may reassert themselves if the alarm condition is still present.
NOTE: A historical error alarm log is viewable in the "Test Mode". The following descriptions suggest possible causes and corrective
actions for each alarm message.
