Do you get the most from your investment in Tank Level Gauges (TLG) Tank Level Gauge definition Level measurement, instrumentation techniques to measure height within a vessel Gauge (instrument), any of a variety of measuring instruments..and the most under-utilised piece of equipment on the forecourt. Today we can harness the connectivity opportunities and the data within the TLG to achieve so much more than just dipping the tanks for fuel volume and ullage space.
TLG Connectivity Example Customer via Remote Wet Stock Management Local Alarm Double Skin Tanks Driver Information System Submersible Turbine Pump Line Leak Interceptor Tank Chamber Dispenser Sump Water (Firefighting) Fuel Level, Volume, Temperature, Water Dry-Run protection
Reconciliation by a high-end TLG Tank Gauge Connecting a reconciling TLG to the POS/FCC to receive sales information opens up a whole range of possibilities for Wet Stock control including: POS or FC Controller Daily or Periodic Business Inventory Reports Variance analysis; dividing variance into Delivery, Temperature and Unexplained Variance Alarms for leak & other loss based on dynamic reconciliation You can see the loss performance of each station; diagnostic capability in the TLG
How do you know what good looks like? > Do you accurately collect loss information for each station? > Is the station loss or network loss acceptable? > When you have a variance, how do you know what caused it? > How quickly would the Site Manager or Head Office react to a sudden changes in behaviour? > How and when would the Site Manager or Head Office team recognise a small change occurring over a long period? > How much are losses costing you annually; how much could you save by reducing loss by x%? Or How much loss reduction (%) is needed in order to justify an investment in remote WSM?
What Cloud Wet Stock Management Delivers Centralised management of data from sites 24/7 response to alarms from on-site TLG and to changes in trend detected in cloud software processing big data Consolidation of management reports to provide accurate and meaningful information on site and network performance Dedicated team of experts dealing with WSM on a daily basis Compliance with legal requirements and oil company rules
How do we get data to the Cloud Install a low cost data collection device to capture real-time data from site and transmit to the cloud Tank Gauge Deliveries (BOL) from customer POS or FC Controller Sales & Inventory from site VPN to Network or GPRS connection to site WSM Service Centre The device captures all sales transactions and 30-second inventory information
Enabling of Wet Stock Management from the cloud With a High end TLG you got: Sales interface and reconciliation TCP/IP or Modem connection AccuChart auto-calibration Business Inventory Reconciliation / Variance Analysis Hourly Reconciliation Monitoring Alarms With a low cost data collection device & simple TLG you can now get: Real-time sales interface and reconciliation TCP/IP or GPRS connection Fuel & Water Height + temperature every 30 seconds AND from the Cloud: Tank Calibration BIR/VA HRM Alarms Theft (Sudden Loss) Meter Drift detection Statistical Inventory Reconciliation (SIR) accredited to US EPA
What Cloud Wet Stock Management Delivers > Line & Tank Leak > Inaccurate tank calibration > Temperature changes > Meter over-dispensing > Theft > Evaporation > Delivery shortages Tank calibration, Delivery shortages and temperature changes have the largest impact on variance whilst meter over-dispensing presents the most immediate savings
Importance of Improved Tank Calibration Sources of Inventory Variance Tank Unknowns: Probe Offset error Diameter error End shape error Length error Tank tilt error 80% A poor tank chart is the #1 source of site variance. Tank Chart Delivery Meter Drift Direct Loss Masking Loss WHY? Theft Vapor Leak Source: FMS, Technical support Simsbury An Accurate Tank Chart is the First Step to Successful Reconciliation
Improved Tank Calibration: Result Auto Calibration > In Auto Calibration the data from the ATG are compared with the Sales Data from POS > Various ATGs offer some kind auto-calibration but best results are obtained by a Cloud Calibration (OSC) due to advanced algorithms and more computing power Before OSC over-read by 6% under-read by 6% After OSC Results > After OSC the errors are near-zero in the region where the tank is typically operated The result is a dramatic improvement in tank calibration and reduced variances

Variance Analysis & Delivery Verification Delivery Variance Temperature Variance Unexplained Variance > Various possible causes: > Calibration > Over/under dispense > Evaporation > (Small volume) Theft > Leak Better understanding of the sources of loss in the supply chain
Delivery Verification: Example Delivery Report Delivery Report > Insite360 compares the delivered volume (from the delivery invoice) with the actual received volume (ATG reading). NOTE: Good tank calibration is needed in order for this to work. Delivery Variances Delivery variances can be investigated by exception
Sudden Loss / Theft Detection Theft/Sudden Loss detected Alarm Raised Event trigger to Customer Notification: ~15 mins! Theft Incidence Customer Informed WSM Services offer real-time theft detection and alarm notification
Diagnostic tools allow detailed interpretation of Alerts from Cloud Software
Case Study 1 Drain-Back > Analysts can access individual transactions to identify causes of loss > In this case a drain-back is diagnosed; the tank gains when idle but there equal losses on the first transaction > Air ingress can be traced directly to the transaction and pump responsible > Cause drain back due to leaking gaskets on the under pump check valves
Case Study 2 Suction Line Leak Overnight gain is only 2.5 litres, but loss on next two transactions is ~25 litres This leak was approximately 22 litres per day.
Case Study 3 Theft from unattended site > Product leaving tank with no sales taking place > ~125 litres lost in 4 minutes > Loss starts at 00:00 and finishes at 00:04 > Customer checked CCTV and found suspicious activity involving the pump being switched to manual mode police involved
Case Study 4 Loss due to water removal > On the face of it a similar pattern to a theft > But our data shows water level reduced during the same period > Site reported a loss (some days later) but WSM services were able to demonstrate the real cause and save the cost of further investigation
Not every loss is a leak most are equipment or data related INVESTIGATION OUTCOMES MAY TO AUGUST 2016 Water Ingress - Tank Chamber 14 % ACV / UPV fault / Filters 13 % Water Ingress - Sump 2 % Tested/No Fault Found 12 % Comms issues 22 % Site Refurbishment 1 % Sensor Replaced 7 % Probe fault 10 % Header Tank Refill 10 % Fill Point 2 % Investigation Processes need to determine Root-Cause Configuration incorrect 1 % Data Improvement 6 %

if you add buying and selling price to the cloud data you enable Price and Margin Management
the same data can also be used for Delivery Planning
And finally; Cloud Computing in our Industry > We are using in limited ways, e.g., > Card authorization / authentication > Lottery tickets > Prices changes based upon real-time data > Loyalty programs with points, price roll-back, promotions, and coupons > GVR remote wet stock management > GVR media on the pump Despite these successes We overly rely on site-level technology, which limits our ability innovate
CLOUD Connectivity will bring DISRUPTION in convenience retail + + Your mobile device has more than enough power to simultaneously run every application at a typical petrol site. What if we could move it all to the cloud? Lower acquisition cost Cloud connected devices report status, problems, and are remotely upgradeable
For Example: 1M GVR devices in the field Goal to connect and tie with Insite360 Devices historically lack native connectivity Data Collection & new forecourt devices new gateway I360 platform to connect all of devices Time to market on new software will be cut, as the service enables push updates Future: mobile, telematics, connected car, and a more consumer experience Retail Consumer Devices Fuel Logistics Dispenser Fleets Predictive Selling (Impulse) Point of Sale ATG Compliance
