PetroNetwork™-S3 Continual Reconciliation System-The S3 system provides precision fuel reconciliation analysis for sites equipped with automatic tank gauging systems and advanced dispenser pump controllers. Upon the completion of every fueling transaction a simultaneous observation of elapsed sales and associated tank system product heights and temperature are recorded. The continual reconciliation system can identify operational problems as they occur in real time and is certified to provide the EPA Leak Detection Monitoring for complex manifold tank systems up to 100,000 gallons in capacity and over 2.7 million gallons in monthly throughput. Among the categories of services encompassed by S3 analysis are the following:
                        1. Quick Reference Precision Inventory Reconciliation for each Product
                        2. Meter Drift Analysis- This is a patented method of identifying meters drifting away from strike and holding back or giving away product. Meter Drift Analysis reports can be provided for each dispenser position associated with a product to identify the financial impact of meter error on site profitability.
                        3. Dispenser Flow Rate Analysis- This procedure calculates the dispenser flow rates for each position associated with that particular product. The purpose of Dispenser Flow Rate Analysis is to identify dispenser positions which are delivering products slowly to the customer because of clogged filters, defective flow arrestors, or inadequate turbine pump capacity.
                        4. Delivery Audit-The S3 continual reconciliation system can identify the gross and net amounts of product that have actually been delivered to the tank system. Because deliveries to retail facilities are not metered when product is introduced to the tank system. WRA’s delivery audit provides a reliable measure of the actual amount of product delivered versus the bills of lading that the supplier is charging for the product. The delivery calculations that WRA supplies are corrected for temperature, tank geometry, and the amount of elapsed sales that occurred while the delivery was being made.
                        5. Blend Ratio Verification – Product blending to create mid-grade gasoline distillates is becoming more common as operators try to use their storage tanks most efficiently. Typically blending ratios are set to meet the octane requirements specified by weights and measures. When these ratios differ from those which should be set, WRA will identify where this is occurring by dispenser position and actual blending percentage.
                        6. Dispenser Theft – When dispensers have been tampered with so that they will not record the actual amount of product withdrawn from the tank systems, WRA will identify the incidents of dispenser theft by date, time, and amount.
                        7. Dispatch Planning- Based upon the sales and tank volumes for products at a location, WRA can predict when the next delivery is required for a tank system and provide optimal load reporting. These calculations are based upon the fueling history at the site, daily sales patterns and predicted fuel usage.
                        8. Repair Validation- When service representatives are conducting dispenser or automatic tank gauge repairs at a facility, WRA can provide an assessment of whether the repairs were effective or what additional work needs to be performed.
