3. Why use Automatic Tank Gauge for Release Detection
Inventory Levels, Temperature Measurements and Delivery information
These measurements are continuously and automatically analyzed for reporting and recording purposes.
In the "inventory mode," the ATG replaces the use of the gauge stick with a In-tank probe that measures product and water levels.
Inventory Control
Using an ATG for daily inventory control provides owners the ability to:
Understand site business cycle (Fuel Consumption)
Delivery Schedule management
Sudden Loss and Theft
Inventory variance gaps
Automatic Tank Gauge
In-Tank Inventory
and
Tank Testing Probe

4. Why use Automatic Tank Gauge for Release Detection
Overfill Alarm Protection using In-tank level readings
When a tank is either 90% full or within 1 minute of being overfilled the ATG system will generate an audible and visual alarm alerting the delivery driver.
External Alarms with horns and lights are typically used to ensure the delivery driver will react to the alarm
Containment Sump & Dispenser Pan Monitoring (New Requirement)
ATG’s can provide continuous monitoring of Secondary containment area’s.
Discriminate between fuel and liquid
Alarm and Notify of a potential environmentally issues
If programmed to do so, shutdown submersible pump systems or Individual dispensers
STP and Dispenser Sensors

5. Why use an ATG for Interstitial and Containment Monitoring
Interstitial Sensors provide continuous monitoring methods per EPA requirements for:
Dry or Wet Interstitial
Containment Sumps (STP, Fill, Dispenser and Other)

Sensor Application Guide

9. Interstitial Sensor for Fiberglass double wall tank
Non-discriminating interstitial sensor for fiberglass tanks detects the presence of liquid in the interstitial space..
ATG continuously monitors Sensor for activity and will generate alarm conditions based on communications, and Float Position
Three Conditions:
Normal
Fuel Alarm
Sensor Out Alarm

10. Hydrostatic Reservoir Sensor
The Hydrostatic Reservoir Sensor accurately detects fluid level change in the reservoir of the interstice of a double wall storage tank. T
This sensor is available in a dual-point or single-point configuration.
The Dual-Point version is ideal for high groundwater areas, and can differentiate between a high level alarm condition and a low level alarm condition.
The Single-Point version can be used in low groundwater locations.
Three Conditions:
Normal
Fuel Alarm
Sensor Out Alarm

11. Interstitial Sensor for Fiberglass double wall tank High Alcohol
Veeder-Root’s Solid State interstitial sensor technology uses light refracting technology to detect the presence of liquid in the double-wall fiberglass tank that contains high alcohol (E-85)
An open sensor triggers a Sensor Out Alarm.

12. Discriminating Interstitial Sensor for Fiberglass Double Wall Tank
Discriminating Interstitial Sensor for double-wall fiberglass tanks uses solid-state liquid level sensing technology
to detect liquid in the interstitial space of the tank.
The sensor can differentiate between hydrocarbons and other liquids.
An open sensor triggers a Sensor Out alarm.

13. Position Sensitive Interstitial Sensor for Steel double wall tank
The sensor for steel tanks detects the presence of liquid between the double walls of the tank. In addition, it provides an alarm when the sensor is not positioned correctly on the bottom of the interstitial space.

14. Liquid Sensor Status Report
Now lets discuss the Liquid Sensor Status Report
If your location is equipped with containment, interstitial and other types of sensors that detect the presence of Liquid in a designated area, this report provides a status report of the alarm state the sensor is currently in. This report provides the proper documentation needed to meet your monthly sensor compliance requirements.

15. Why use Electronic Line Leak Detection with an ATG
Veeder-Root’s patented measurement technology tests lines at full pump pressure for highly accurate 0.1 gph precision,0.2 gph and 3.0 gph gross testing.
Wide range of piping types
Eliminates Slow Flow from thermal contraction

Number of tests passed in the previous 24 hours
Number of tests passed since midnight
Displays the last years 0.20 gal monthly tests
The Pressure Line Leak Test Results will display the results of the 3 GPH, .2 and .1 if programmed.
The PLLD system attempts to run a 3.0 gph test after every dispensing transaction. The last 3 gal test is posted along with the number of 3 gal tests performed in the past 24 hours and since midnight.
The pressure line leak report lists the previous years .2 test. The first passing test of the month is recorded.
The 0.1 Gal test portion of report is similar to the 0.2.
Displays the last years 0.10 gal monthly tests

17. Why use an ATG for Wet Stock Management
Wet Stock Management using Automatic Reconciliation
Wet stock Reconciliation is the management of liquid stock, stored on the site, e.g. petrol, diesel, kerosene etc. It is based on the same theory of any stock control system, that is measuring the amount of stock delivered into the storage tanks, subtracting the amount sold, and measuring what is left in stock.
ATG’s capable of monitoring Dispense, Delivery and Inventory activity may have the ability to provide Reconciliation results to meet business and regulatory needs.
Automatic reconciliation provides a highly accurate accounting of your wet stock control.
Helps meet state and local inventory control requirements
Reconciliation Reports
Shift, Daily, Rolling and Periodic
Variance Analysis
Labor and time savings
Using the ATG provides efficiencies when gathering and recording the inventory and compliance data used to manage your locations. It also provides

18. In-Tank Static Testing
One of Veeder-Root’s methods of in-tank testing is Static Tank Testing. Static testing utilizes In-tank probes, which employ Magnetostrictive principles.
Mag probes use six-point temperature sensors to provide accurate temperature compensation required for in-tank leak testing capabilities.
The tank must be removed from service and remain “Static” for a period of time.
The test time period is dependent on many factors
Delivery wait period = 8 Hours
Test Time = 2 to 8 hours
Threshold = 0.07 (0.1 test), 0.13 (0.2 test)
Tank Size = up to 30,000 gallons
Minimum Level = Approx. 18” to 39” (Automatic)
Throughput = N/A
Manifolded Tanks = Not supported

19. In Tank Test Results DEC 16, 2010 2:35 PM LEAK TEST REPORT
T 1: UNLEADED GASOLINE
PROBE SERIAL NUM:
TEST STARTING TIME:
DEC 10 , :23 PM
TEST LENGTH = 4.7 HRS
STRT VOLUME = GAL
START TEMP = 58.7 F
END TEMP = 58.1 F
TEST PERIODS 2-7
LEAK TEST RESULTS
RATE = GAL/HR
0.20 GAL/HR TEST PASS
Lets review what is on the Leak test report.
The probe serial number for the probe assigned to the tank is listed.
The start time and the duration of the test indicate how long the test ran.
Fuel temperature is important, a swing in temperature will cause the product to expand or contract changing the tank volume.
During the leak test each half hour the console logs the accumulative leak rate. The first half hour results are ignored, in our example test periods from 2 – 7 are shown.
Test results are either passed, failed, or Invalid: Pass indicated that the tank test passes and the leak rate is below the threshold. A failed indicates that the volume change in the tank was greater then threshold. Invalid indicates test conditions were outside of acceptable range, reasons for an invalid include recent delivery, low fuel level, temperature out of range.

20. Continuous Statistical Leak Detection (CSLD) Test Results

25. Item # 1 is illustrating the Automatic Tank Gauge and STP Control Box
The ATG allows you to monitor multiple areas at your facility, such as the inventory in your tanks , containment areas that require liquid sensing. In addition to the ATG in your station you will also have a submersible Turbine pump control Box. This provide power to you r STP’s that deliver fuel to your dispensers
Now moving over the Item, # 2 IN the tank, this shows you the components that may be in your fuel tank and or tank farm area. Such as containment sensors, In tank inventory and tank testing probes, the Submersible Turbine Pump and other sensors.
Now lets quickly talk about the dispenser/pump area. This has multiples components that are design for safety and ease of use. Such as the breakaway device, this ensure that if a customer drives off with the nozzle in their car that it breakaway to avoid the dispenser from being pulled over. In addition to the Nozzle must installation have some sort of swivel which allows the customer to easily point the nozzle in the proper direction
