Automatic Tank Gauging Systems For Release Detection: Reference Manual (August 2000) 1

 For UST Inspectors:

 How Can You Use This Booklet?

The following pages present “system descriptions” of automatic tank gauging (ATG) systems used

to monitor release detection at underground storage tanks (USTs). As an UST inspector, you can

use this information to evaluate systems and to educate UST owners/operators. Each

description of an ATG system provides information on how the equipment works, its specifications

and limitations, its operation and maintenance requirements, and how to print and read reports.

Systems Described Here Have Passed Third-Party Evaluation

All ATG systems described in the following pages are taken from the “List Of Leak Detection

Evaluations For USTs,” which is maintained by the independent National Work Group on Leak

Detection Evaluations, consisting of State and EPA UST program staff. All ATG systems listed

here have been evaluated by third parties and certified by them to meet the federal requirements

for detecting leaks at a minimum rate and within the prescribed probabilities for detection and false

alarm. In short, if the system is listed here it has been evaluated and passed third-party scrutiny.

You can access the most current “List” at EPA’s Web site at

http://www.epa.gov/oust/pubs/ldlist.htm.

Use As An Inspection Tool: 

Look Up System Descriptions Quickly

As an UST inspector you face a wide array of release detection devices that you must evaluate to

see if they are installed, operated, and maintained properly to detect leaks efficiently. For any ATG

system you encounter in the field, you should be able to quickly find a system description in the

following pages that will help you evaluate the system’s application at the site. Use the table on

pages 4 through 6 to find what page to go to for a system description of a specific leak detection

system (identified by vendor and model name and/or number).

Use As A Compliance Assistance Tool: 

Leave System Description With UST Owner Or Operator

You can provide valuable compliance assistance and “education” as you walk the UST

owner/operator through a copy of the system description from the reference manual — note how

the device is used, its limitations, the necessity of following maintenance instructions from the

manufacturer, how to print and read reports, and so on. To help you in this educational task, this

manual includes a two-sided handout (“For UST Owners And Operators”) you can copy and leave

at the UST site (see pages 7 and 8), along with copies of other appropriate pages from the system

description.

 For UST Owners And Operators:

 How Can You Use The “System Description” Of

 Your Leak Detection?

Automatic Tank Gauging Systems For Release Detection: Reference Manual (August 2000) 7

As the owner or operator of an underground storage tank (UST) system, you should make sure

your vendor or installer provides you with the information and training necessary to guarantee your

release detection equipment works effectively to detect leaks. 

If you don’t know how your system works, you will fail inspections and may find yourself with

violations and penalty fees. Or even worse, you may find too late that you have had a leak and you

may now have to pay for extensive cleanup of a contaminated site and for damages caused to

others. It is your responsibility to know how to operate all protective devices properly so that you

meet regulatory requirements that protect the environment.

The “system description” of the automatic tank gauging (ATG) system left with you will help you

get started. The outline on the back of this page explains how you can understand each heading in

the system description. 

But to really know your equipment, you should contact the vendor listed and make sure you get full

documentation for your leak detection system — such as an owner’s manual or schedules for

when recalibration is necessary or when regular maintenance is needed. Also, you should make

use of any training provided by the vendor or someone else that would ensure that you operate

and maintain your system properly.

Special Note If You Have Manifold Tanks: The information provided in the accompanying

system description is largely for single tanks that are not part of a manifold system of

interconnected multiple tanks. If you have a manifold UST system, you need to look carefully at

your system description to see if it has been evaluated for use with manifold tanks. If you discover

that the ATG system has not been evaluated for manifold tanks, there is still a possibility that it

may work if you can functionally separate the tanks — basically cancelling the “manifold”

interconnection of tanks — which may be possible if the tanks have a valve system or other

mechanism that can isolate tanks for release testing. That’s a lot of “ifs,” so you must check with

your vendor, installer, or manufacturer, as well as your state regulatory agency, for help in

understanding how you should act in this situation involving manifold tanks.

PLEASE NOTE: The information given to you in the accompanying system descriptions

comes from third-party evaluations and from release detection equipment vendors. These

sources alone are responsible for the veracity of the information presented here. EPA does

not endorse any specific release detection devices. EPA has gathered this information from

third-party evaluators and vendors and is distributing it solely to provide UST

owners/operators with basic information. Each user should take the next step of contacting

the vendor for further confirmation or help.

To generate basic status, leak detection test, and alarm history reports, you will use the STAT

command and HISTORY command. Specific instructions for generating these reports follow.

Inventory/Status Reports

You can generate a status report from the Status (Stat) Screen. This report can tell you, among

other things, how many tanks are being monitored, what type of fuel is in each tank, how much

water and product are in the tanks (as well as the temperature compensated volumes), and the

current leak rate of each tank.

To view the Status (Stat) Screen:

For more detailed inventory/status information you can generate a Fuel History Report, which

describes the tank level, volume, ullage, and fuel usage for eleven of the most recent twelve hour

periods, or a Delivery Log Report, which describes the temperature, volume, date, and time, by

tank, at the beginning and end of the last eleven deliveries. You generate both of these reports

from the History Menu. 

To generate a Fuel History or Delivery Log Report:

Log in as described above

 Type HISTORY after the R> prompt; a list of history commands will appear

 Type FUEL HISTORY 1 or DELIVERY LOG 1, as appropriate, after the R> prompt

Change the suffix following the name of the report if you wish to view reports older than the eleven

most recent. For example, type FUEL HISTORY 12 for the eleven twelve-hour periods preceding

the eleven most recent. If you wish to view one of these reports for only one tank in a multi-tank

system, identify the number of the tank after a space following the numerical suffix. For example,

a Fuel History Report showing the eleven most recent twelve hour periods for just tank 1 would

require you to type FUEL HISTORY 1 1.

Delivery reports can help you determine if leak test results might be affected by introduction of

product during a test, or this data can be used to perform statistical inventory reconciliation to

validate the results of in-tank leak detection tests.
 Andover Controls 

 Infinity/Continuum TMS: Sample Reports (continued)

Leak Test Reports

The Infinity TMS can also generate leak test reports, which provide detailed information on the

most recent leak tests performed by the system. The Infinity TMS will automatically attempt to

perform a leak detection test daily, so unless the system has been programmed to perform

differently, you should have daily leak detection test results for each tank attached to the system. 

To print a Leak Test Report:

 Log on as described above

 Type LEAKLOG 1 after the R> prompt; this will display the results of the four most recent leak

tests, log index numbers (LOG NBR) one through four

To get the results of preceding leak tests, change the number following LEAKLOG. For example,

to obtain the results of the four leak tests that proceeded LEAKLOG 1 results, enter LEAKLOG 5,

which will display results for leak tests with LOG NBRs five through eight.

Infinity TMS leak test results and their meaning are shown below:

 PASSED: test was able to run for the minimum test time, and during the test, the temperature

compensated volume remained the same or increased or decreased less than 0.1 gal/hr

 FAILED: test was able to run for the minimum test time, and during the test, the temperature

compensated volume increased or decreased more than 0.1 gal/hr; such increases or decreases

of greater than 0.1 gal/hr may be attributable to product leaking from the tank or the influx of

groundwater into the tank

 INVALID: test stopped before completion due to delivery, dispensing, or probe hardware alarm

or loss of system communication 
 Andover Controls 

 Infinity/Continuum TMS: Sample Reports (continued)

Automatic Tank Gauging Systems For Release Detection: Reference Manual (August 2000) 15

If the Infinity TMS reports that the tank failed or that the test was invalid, you should investigate

further to determine the cause of a possible leak. The system can reliably detect leakage rates of

0.2 gph or higher, and was third party certified as such, but reports that a tank failed if it detects a

leak of more that 0.1 gph. 

Alarm Reports

You can also generate reports that tell you what types of alarm events have occurred for a tank

system in the past, or what alarms are currently triggered. The Alarmlog Screen displays the most

recent alarm events. 

To generate an Alarmlog Report:

 Log on to the system as described above

 Type ALARM LOG 1 at the R> prompt

Change the suffix following the name of the report if you wish to view reports older than the eleven

most recent: For example type ALARM LOG 12 for the eleven alarm events preceding the eleven

most recent.

Finally, you can generate reports that differentiate between alarms generated to inform the

operator that the level of the tank is too high or low, or that theft has occured, and alarms

generated to inform the operator of a leak, an incomplete leak test, or other alarms. These reports

are called the Levelalarms Report and Tankalarms Report respectively.

To generate a Levelalarm or Tankalarm Report:

 Log on as described above

 Type HISTORY at the R> prompt; a list of HISTORY commands will appear

 Type LEVELALARM 1 or TANKALARM 1, as appropriate, to generate a report of the eleven

Leak Test Reports

The Tank Manager system can display leak test results graphically on screen in two ways. First,

the Test Summary Display is a bar chart, one chart per tank, which displays the gallon per hour

volume change rates for the last 15 tank leak tests. Each bar on the chart represents the results of

one test. On the left hand axis of the bar chart on the screen, you will find the scale for the volume

change rate, marked as plus (into tank) and minus (out of tank) gallons or liters per hour. To the

left of the bar chart, you will see a box which displays the depth, volume, and temperature of the

fuel in the tank, the volume and temperature change for the test, and the month, day, and time of

the test. The Last Test Detail Display shows you only the results of the last test that was run on

each tank. 

To view the Test Summary or Last Test Detail Display:

 Press DSP MENU

 Press 3 (press 6 to view Last Test Detail Display)

 Use the [ARROW] keys to move between details of various tests

Or

 Press [ARROW] to position the cursor over the TEST SUMMARY or LAST TEST DETAIL option

in the DSP MENU and press ENTER

You can also print a Test Summary Report, which is a concise summary of the last 15 valid leak

detection tests run on each tank. The following conditions may result in invalid test results, which

are not saved: recent deliveries, large temperature changes during a test, not enough quiet time

during the six hour test window, or low tank volume. A Test Summary Report is shown below:

If the Tank Manager system detects an increase or decrease in volume greater than 0.2 gph,

based on the results of the last complete leak test, then the system will show the test alarm

indicator, TA, on the LCD. If the Tank Manager system reports such an event, the operator should

investigate to determine the cause of a possible leak.

Alarm Reports

You can view current alarm indicators on the STAT display screen (described above). These

indicators appear as text (defined below) flashing against a dark background. For example, if the

last leak test showed a loss or gain in volume of 0.2 gph or more, TA will flash beside the tank

number on the Stat Display. A list of alarm indicators relevant to the tank, volume, water level, and

sensors follows:

Tank

 TA: last leak test showed a loss or gain in volume of 0.2 gph or more

 C: tank probe is not detecting level and may require service

 T: no tank test has been completed for 21 days

Volume

 HI: tank is filled above the high volume alarm set point

 LO: tank volume is below the low volume set point

Water

 HI: water level in the bottom of the tank exceeded the high water set point

Sensors

 LIQ: one or more defined sump or interstitial sensors are in alarm

 VAP: one or more vapor sensors are in alarm

 BRN: brine sensor shows low or high level

 LNE: 3.0 gph pressure line leak test has failed

You can view historical alarm and sensor information by requesting from the Tank Manager

system an Alarm History Display (shown below) or an External Sensor History Display. The Alarm

History Display shows the date and time, type and location, and applicable numerical details of the

last seven alarm conditions detected by the system. The External Sensor History Display shows a

graph of one week’s liquid, vapor, and brine sensor results. The box on the left hand side of the

display shows the subchannel, type of sensor, and recorded value for each of the sensors. You

can change the set of sensors displayed by pressing the NEXT key, or move between days by

pressing the [ARROW] keys to move the cursor on the graph.

Automatic Tank Gauging Systems For Release Detection: Reference Manual (August 2000) 35

In addition to the Inventory Status Report, the EECO System TLM will automatically print a

Delivery Report approximately two minutes after the end of a delivery. This report includes the

total gross and net volume added to the tank, plus the starting and ending inventory, but does not

account for fuel dispensed during the delivery process. You can see historical delivery information

by requesting a Delivery Status Report, which provides the date, time, gross and net volume of

each tank for the last 10 deliveries. Delivery reports can help you determine if leak test results

might be affected by introduction of product to the tank during a test, or you can use this data

along with usage data to perform statistical inventory reconciliation to validate the results of in-tank

leak detection tests.

Leak Test Reports

You can set the EECO System TLM to run a leak detection test, program the system to test at

specified times, or set the system to run in a continuous leak detection mode, where the system

will perform a test automatically after product is dispensed. The sensitivity of the leak test you run

is generally set at system start-up. 

To run a manual leak test:

 Press CHANGE

 Press LEAK TEST

 Press ENTER twice

 Press CHANGE; “NO” will flash

Each of the above on-screen displays is also available in a printed report. Each time a scheduled

leak test is complete, the EECO System TLM will produce a Leak Test Report. This report shows

the test type, leak rate threshold and confidence level, last delivery, tank capacity, test time and

length, and changes in volume, product temperature, and water level. The report indicates

whether the tank has passed or failed based on the leak rate derived from the data described

above. You can also request this normally automatic report as a Last Test Ran Report.

Leak Test Reports

You can program the TMS 500 to perform leak tests automatically, or you can manually start a

leak test. The steps to starting a leak test and an example of a leak test report are displayed

below:

To initiate a leak test:

 Press TEST; the system queries you to select

a tank as above; if you wish to select all tanks

simply press ENTER, otherwise enter the

tank number and the system will display:

 Press ENTER; the system will query, SURE?

 If sure, press ENTER

The TMS 500 reports that the tank either passed or failed. If the report shows that the tank failed,

the operator should investigate further to determine the cause of a possible release. Conditions

that might indicate that the test was invalid rather than leaking, include the following: delivery

within 6 hours of the test, changes in temperature greater than one-half of one degree from the

beginning to the end of the test, and finally, differences in water level. 

You can also print a Leak Estimate Report and a Reconciliation Report. The Leak Estimate Report

lists the test rate in volume/hour, percent of gross capacity, gross and net volume, level,

temperature, water volume, water level, and the minimum amount of time needed to complete the

test. The Reconciliation Report includes the time and date, gross and net volume, and product

level at the start and end of the reconciliation period, as well as the gross and net delivery, and

gross and net usage.

Leak test results will show whether each tank in the system passed or failed, or if the test was

short or invalid. A tank passed if the volume change (if any) was less than 0.2 gph. A tank failed if

the volume change was greater than +/- 0.2 gph. Short test results indicate that the test duration

was too short to yield valid test results. Invalid test results indicate that the system detected a leak

rate greater than +/- 0.2 gph, but that one or more of the tank conditions was outside of

acceptable parameters. Invalid tests will cause the system to print at the end of the test a report

which shows which conditions were unacceptable.

Basic System Description:

The basic systems from Marconi and Veeder-Root are essentially identical. Each system is an

inventory and line leak detection system consisting of a console with liquid crystal display,

alphanumeric keypad, and in-console printer. The systems can monitor up to eight single-wall,

underground storage tanks (UST) and can be configured with various monitoring, reporting,

warning, and alarm capabilities. The systems are equipped with audible and visual alarms,

triggered by in-tank alarm conditions. Any of the in-tank alarm limits can also be tied to relays to

trigger on-site devices, such as overfill alarms, or to shut down submersibles. The Marconi

EMC/PC utilizes the same leak detection software attached to a personal computer. The VeederRoot TLS-300C is capable of monitoring one or two double-wall tanks, while the TLS-300i system

monitors up to four double-wall tanks.

Certified Leak Rates and Thresholds:

Basic System Description:

No information regarding the Hasstech system was provided by the vendor. The Patriot Sensors

7021 and Ronan systems are virtually identical in terms of appearance and operation. Patriot

Sensors 7021 can be set up utilizing either the 7030 or the 7100 series magnetostrictive probes,

though most newer systems utilize the 7100 series. Operation of the 7021 console is not

dependent on the probe type. Both systems utilize an alphanumeric liquid crystal display (LCD)

that provides instant feedback for up to eight tanks, including product gallons, depth in inches and

temperature, as well as alarm warnings and reports. All reports can also be generated in hard

copy with the system printer.

Basic System Description:

The Site Sentinel II manages up to 128 probes or sensors connected to a series of up to eight

Smart Modules. The system can provide continuous leak detection and accept input from a variety

of sensors: liquid, vapor, sump, reservoir, liquid phase, and interstitial. The system also interfaces

with cathodic protection and line leak detection systems, and provides an audible alarm in addition

to a visual alarm indicator on the controller face panel. The Site Sentinel II is operated via a builtin keypad and display, an on-site terminal or PC, or with a modem, via an off-site terminal or PC.

The system may include a factory installed printer for generating hard copy reports. The Site

Sentinel III offers the same capabilities, but utilizes a compact desktop controller, instead of a

built-in keypad and display. This configuration is designed for remote and unattended monitoring

applications. No information on the Petrosonic III model was provided by the vendor.

The functionality of both models is nearly identical. The main differences are in the hardware. The

Model II utilizes a backlit, liquid crystal screen to display tank information, while the Model III

displays tank information on a normal computer monitor. You will see the same menu screens and

reports regardless of the type of display. You will generate printed reports on the built-in printer

(Model II), if it has been installed, or a printer attached to the PC or terminal controller.

The keypad (Model II) has several multi-function keys. The CLEAR/NO key either erases an entry

or field, or answers NO to a prompt. The ENTER/YES key either finishes an entry or answers YES

to a prompt. The HELP key may not be functional on some models. The CANCEL key will back

you out of the current menu, or cancel the previous command. You print most screens by pressing

the ?*-/0 key on the keypad, or by typing P at the terminal. Only screens with PRINT on the bottom

Leak Test Reports

The Individual Events Menu (option 10) allows you to view reports on 17 specific events: overflow,

low product, high water, bad temperatures, thefts, deliveries, sales, timed leak test, high sensor

levels, low sensor levels, I/O module inputs, input #1 contact closures, input #2 contact closures,

probe failures, module failures, printer failures, power failures. Option 8 will generate the timed

leak test report. This report provides both the leak rate of a particular tank and an indication of

whether a leak has been detected.

To generate a Timed Leak Test

Report:

 Type 8 at the Individual Events

Menu prompt

 Press Enter

 Press ?*-/0 on the keypad or type 

P at the terminal to print the report

This example report indicates a leak rate of 0.6104 gph for the tank in question. Since the leak

rate exceeds the 0.2 gph regulatory limit, the tank has failed the leak test and the report displays

LEAK INDICATED. You should not excavate your tank based only on the evidence of the timed

leak test. Further testing should be conducted to confirm the results of the timed leak test. The

owner and operator must also comply with the procedures of 40 CFR Section 280.50 for reporting

suspected releases.

The keypad of the EMS-3500 consists of control keys (gray or red background) and data entry

keys (white background). The control keys are used to display information for selected tank(s) or a

manifold group of tanks, and to obtain printed reports. The data entry keys are used for requesting

information on a particular tank or event. The CLEAR key is used to remove data entered into the

system and to silence audible alarms. The FUNCT. key is used to shift the data entry keys from

numeric to data for viewing tank information on the liquid crystal display (LCD). The TANK key is

used to designate a specific tank for viewing information, or starting ATG leak checks.

The key switch on the EMS-3500 control panel is used to select one of the three operating modes

of the system: Normal, ATG Leak Test, and Maintenance. When the EMS-3500 is in the normal

operating mode, the LCD will continuously display the current time in hours, minutes, and seconds

using a 24-hour format. When requested, the LCD can display the current tank readings, last

delivery information, current alarm conditions, and the time and date. 

To display tank information:

 Press TANK, followed by the tank number (using the number keys) 

 Press FUNCT., followed by the function key (the number keys) corresponding to the desired

tank information (e.g., product level, temperature, alarms) 

Inventory/Status Reports

The Status Report contains the current information on the status of all the probes in the system. It

will also contain current inventory information if the system utilizes ATG probes, as well as any

current alarm/warning conditions. You may print a Status Report any time the console is in the

normal mode of operation. 

To print a Status Report:

Sample Status Report (continued)

*Designates probe in alarm condition

Leak Test Reports

The EMS-3500 provides four methods in which the console may run automatic tank gauge leak

tests: manual, timed leak test (TLT), automatic leak test (ALT), and remote. Regardless of the

means of activation, the leak test will be terminated automatically by the the EMS-3500 console. 

Manual Leak Test

When you put a tank into leak check mode from the console keypad, the test for each tank must

be started individually. This allows some tanks to remain in operation while other tanks are being

tested. The system will automatically end and print out the results of the leak tests once they have

been started. The user may also choose to manually end the leak test, though this may lead to

inconclusive results. 

To start the Manual Leak Test: 

 Turn the key switch to the ATG LEAK TEST position 

 Press TANK, followed by the desired tank number; the display will show the tank number,

followed by an N overlaid by a blinking cursor 

 Press the 0(ON) key; Y will appear on the display and a Leak Test Enable Report will be printed;

if the automatic leak test or timed leak test features are enabled, the message, ALT ACTIVE or

TLT ACTIVE, will be displayed and no other action will be taken by the system; these automatic

and timed tests will test the system during quiet (down) time and at regular intervals; reports will

be printed by the system at the completion of these tests 

 Return the key switch to the NORMAL position; if the automatic or timed test features have not

been enabled, the system will run the leak test and automatically end the test once completed;

examples of the Leak Test Enable Report and Disable Report (printed at the completion of the

test or when the test has been disabled) are shown below:

In this example, the leak rate of -0.050 for the tank in

question is below the regulatory thresholds of 0.1

gph (annual) and 0.2 gph (monthly), thus the system

indicates that no leak has been detected. 

You can program the EMS-3500 to run leak tests at defined start and stop times (TLT), or to

automatically begin leak tests during quiet times when no fuel is being dispensed or delivered

(ALT). If the system has been unable to perform an automatic test, you can configure the system

to notify the operator that a conclusive leak test has not been performed on a particular tank and

that adequate down time must be provided to allow a test to run.

The system can also generate theft detection reports based on programmed time intervals, self

test reports (detailing the internal diagnostic routine), and an automatic power outage report.

Once the system is set up properly, all standard system reports (e.g., inventory, leak alarm) can

print automatically. You can view tank and fuel information at any other time by using the keypad.

The system display typically shows no activity (for which the system displays the current date and

time, an alarm condition, or a command in progress). While in the no activity or normal mode, you

can display information on tank levels, volume, etc. While an alarm condition is being displayed,

the system will accept no commands other than ALARM RESET.

The keypad is organized with the command keys in the right-most column. When you need

system information (e.g., tank levels), press DATA. When you want to begin or end a leak test,

press LEAK CHECK. Press ALARM RESET to clear the alarm being displayed. The * key is

reserved for special functions and will otherwise be ignored by the monitor.

To use the keypad, press and hold the desired key until the system recognizes it. The keypad will

function better if the keys are held down longer. 

Press the DATA key to access one of the modes of operation. The system will request a category

number between 1 and 5:

1. Display commands

2. Print commands

3. Report commands

4. Profile commands

5. Diagnostic commands

You can view tank information on the local display by selecting mode 1. This mode of operation

will enable you to select from the following information for each tank to display:

1. Product level

2. Water level

3. Average temperature

4. Product volume

5. Combined tank data

6. Contact monitor status

The system will prompt you for the tank number for which the data is requested. 

You can print tank information on the internal strip printer by selecting mode 2 (print mode). The

system will accept two commands in this mode (depending on software version, the system may

not accept Command 1):

1. Combined tank information

2. Tank volume table

When you select either command, the system will request the tank number for which the

information is requested. When selected, the combined tank information command will prompt the

system to continuously print new tank information (product volume, water volume, ullage, product

level, water level, and temperature) for the selected tank. You must press CLEAR or ENTER to

stop printing. The key must be pressed and held down until the system recognizes it (the system

stops printing or the screen goes blank).

When you select the tank volume table command, the system prints a table showing the adjusted

volume of the tank at inch increments. The system adjusts the volume to compensate for tank tilt.

It is suggested that you print this report for each tank immediately after startup, and file the report

as a permanent reference, which can be used if the system is unavailable for any reason or the

system is reconfigured.

You can print all system reports at any time by issuing commands in Mode 3: Report Mode. 

 From the default display, press DATA; the system will prompt the user for a mode number

 Press 3; the display will then prompt the user for a command:

The system will accept commands for the following reports:

1. Inventory (Current)

2. Delivery

3. Product Thruput

4. Leak Test

5. Alarm History

6. Inventory (Captured)

Inventory/Status Reports

To generate the Inventory Report, first put the system in

Report Mode (see above):

 Enter 1 at the command prompt

 Press ENTER; the system will indicate that it is printing the

inventory report

After the report finishes, the system will prompt you for the

next command. You can use the CLEAR key to exit the

Leak Test Reports

You can configure the system to run leak tests automatically, or you can manually start a leak test.

To start the leak test manually, ensure the system is displaying the default screen (system time

and date) and press the LEAK CHECK key. The system may prompt you for a PIN code if the

system has been set up to prevent unauthorized access. After you enter a PIN code and press

ENTER, the system begins the leak test. The display shows a running clock to indicate proper

system function in place of the system date and time. 

The leak test will run until either 24 hours elapse, or the test is stopped manually. If the test has

been started manually, you must stop it manually. Once a leak test has been started manually, the

system disables scheduled automatic testing until the next day (midnight).

After the leak test finishes, the Leak Report will print automatically. The information in this report

represents the results of the last leak test completed and will not be released until another leak

test completes. An example Leak Report is shown below.

Test results are given on an

hourly basis (gallons leaked

for one hour)(+x.xx = gallons

into the tank, -x.xx = gallons

out of tank,   = out of

range (more than 9.99)).

Note: The test in the

example shown was run for

only eight hours, thus only

eight lines of data are

displayed.

Following the hourly data, the

system prints the end values

for the test, including the end

date and time, and a test

summary detailing the highest

leak rate per minute, the

average leak rate per hour for

the entire test, and the test

status.

Once the report is printed, you should verify that it appears correct. 

You should:

 Check the start and stop times. Are they correct?

 Verify that the start and end volumes and temperatures for each tank appear correct.

 Check the number of hours the test ran (if the test ran for more than 55 minutes during any hour,

that should be considered an hour. The number of lines printed in the hourly data section should

equal the number of hours. If the wrong amount of lines are present, check if the power failed

(check the test status).

 Check the test status listed at the end of the report. If the status is other than 01, the test may be

invalid for small leaks. Status codes of 90 (product loss), 91 (product gain), or 92 (water

change), may still indicate a leak if the code cannot be explained by a condition which occurred

during the test (such as product was dispensed).

 Check each line of hourly data per tank to verify that all the hourly leak rates appear reasonable.

(If a line shows -9.55 gallons for that hour, product was either dispensed, which invalidates the

test, or a major leak occurred).

 Check the high leak rate per minute listed at the end of the test. If it is much different than any of

the hourly leak rates, then fuel may have been delivered or dispensed during the test, which

invalidates the test. 

 If all test data appear normal, the average leak rate at the end of the test and the test status

should be used as a leak indicator.

In the sample report above, Tank 1 shows an average leak rate of -0.04 gallons per hour during

the 8 hour test. Since this is within the limits of a 0.2 gph test, this tank is probably not leaking.

Since this is not guaranteed, further testing should be used to verify the results (by running the

same test again and/or looking at other leak indicators). Tank 2, however, shows an average leak

rate of -3.50 gallons per hour for 8 hours or a loss of 28 gallons from the tank. This would indicate

that either a very large leak exists or that 28 gallons of fuel was dispensed (or stolen) during the

test. The user must resolve the reason for the loss.

Positive leaks can exist. A leak of +0.10 for 8 hours may indicate that 0.8 gallons of water leaked

INTO the tank. This can occur if the tank leak is below the groundwater level. 

During the leak test, the system will monitor conditions which can invalidate the test. These

conditions will be printed in the form of status codes at the end of the test. The possible test status

codes are:

01 = No test errors detected

20 = Calculation overflow error (during leak rate calculations)

90 = Product loss error

91 = Product gain error (a delivery was detected)

92 = Water change error

93 = Power failed during test

If the following errors occur, the gallons/hour high and average information will not be printed on

the report:

94 = Not used

95 = Temperature deviation error

96 = Level deviation error

97 = Level probe fail

98 = Tank profile error

99 = Test did not run for more than 1 hour

You can also request a Leak Report while in report mode. At the command prompt, enter 4 and

press ENTER. The system will print a leak report detailing the results of the last leak test

completed. Regardless of how it is generated (following a leak test, or manually), all leak reports

are identical in appearance.

In order to pass a monthly test, a tank’s leak rate may be no higher than +/-0.2 gallons per hour. In

the example above, all leak rates are below this threshold; therefore, all the tanks have passed. If

N/A appears on the report, not enough data was collected to successfully run a valid precision

leak rate test.

At any time during the month, the system may replace a previous precision test. A test will only be

replaced if the tank’s leak rate is within the set threshold and the product volume is higher than

that of the previous test. At the beginning of each new month, the previous monthly report will be

saved.
