Why use Automatic Tank Gauge for Release Detection Automated process to monitor: Underground Tanks- (Tank Testing to meet UST Compliance needs) Above Ground Storage Tanks (Inventory Control) Containment Sump Monitoring Dispenser Pans Monitoring Product lines- Meet 3.0 GPH requirements Other areas of leak sources Automatic Tank Gauge In-Tank Inventory and Tank Testing Probe

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

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

Sensor Type and Applications Sensor Application Guide

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

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

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.

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.

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.

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.

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

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

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

In Tank Test Results DEC 16, 2010 2:35 PM LEAK TEST REPORT T 1: UNLEADED GASOLINE PROBE SERIAL NUM: 627020 TEST STARTING TIME: DEC 10 , 2010 11:23 PM TEST LENGTH = 4.7 HRS STRT VOLUME = 2123.9 GAL START TEMP = 58.7 F END TEMP = 58.1 F TEST PERIODS 2-7 -0.01 -0.02 -0.01 -0.03 -0.05 -0.04 LEAK TEST RESULTS RATE = -0.01 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.

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
