Solution Overview

Problem

Fuel dispensers at fueling stations experience meter drift between annual calibrations, leading to inaccuracies in fuel dispensing, which can result in customer or station losses, inventory discrepancies, environmental contamination, and non-compliance with regulations, with existing systems failing to detect these issues in a timely manner.

Innovation Solution

A system and method for real-time determination of meter drift using predictive modeling and physics-based fluid balancing, incorporating sensors and data processing to estimate and quantify losses due to meter drift, utilizing predictive models and error correction techniques to account for discrepancies in fuel storage facilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If annual calibration of flow meter is performed, then measurement precision is maintained, but time between calibrations allows meter drift to occur causing loss of measurement precision

Engineering Contradiction:
Improveflow meter calibration accuracyVSAvoidtime between calibrations
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary detection of meter drift conditions by continuously monitoring fuel storage facility data and comparing actual fuel levels against predicted levels based on sales and deliveries. This early warning approach allows calibration to be performed just when needed, rather than on a fixed annual schedule, thereby maintaining measurement precision while minimizing unnecessary calibration intervals.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements continuous feedback monitoring by tracking fuel inventory levels, sales transactions, and delivery records to detect deviations indicating meter drift. When drift is detected, the system generates alerts prompting calibration action. This feedback loop ensures measurement precision is maintained by triggering calibration only when actual drift occurs, optimizing the balance between calibration frequency and measurement accuracy.

Inventive Principle:
Principle #23Feedback

2Measurement precision

If frequent monitoring of meter drift is implemented, then measurement precision and compliance are improved, but device complexity and operational costs increase

Engineering Contradiction:
Improvemeter drift detection accuracyVSAvoidmonitoring system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system uses existing infrastructure components (fuel dispensers, point of sale systems, delivery records, and automated tank gauges) to automatically collect and analyze data for meter drift detection. By leveraging these self-existing data sources and processing capabilities, the system achieves frequent monitoring without requiring additional complex hardware or manual intervention, thus improving detection accuracy while minimizing added complexity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The monitoring system is designed to serve multiple functions: it tracks fuel inventory levels, monitors sales transactions, records deliveries, detects meter drift, and generates compliance reports. By making the system multi-functional and integrating these capabilities into a unified platform, the patent reduces overall system complexity while enabling comprehensive meter drift monitoring and measurement precision maintenance.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Object-affected harmful factors

If real-time meter drift detection is implemented, then losses and environmental risks are reduced, but implementation costs and system complexity increase

Engineering Contradiction:
Improveenvironmental contamination riskVSAvoiddetection system complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The system introduces an intermediary analytical layer that processes data from existing infrastructure components (dispensers, tank gauges, POS systems) to detect meter drift conditions. This intermediary layer translates raw operational data into actionable drift detection without requiring direct modification of existing equipment, thereby reducing environmental risks through real-time detection while minimizing the complexity increase associated with implementation.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Measurement precision

If predictive modeling is used to detect meter drift, then measurement precision is maintained between calibrations, but computational resources and processing requirements increase

Engineering Contradiction:
Improvefuel dispensing accuracyVSAvoidcomputational processing energy
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The system applies predictive modeling selectively rather than continuously processing all possible data. It focuses on key indicators such as fuel level discrepancies, transaction volumes, and delivery records to detect meter drift. By applying computational analysis only when relevant data patterns suggest potential drift conditions, the system maintains measurement precision while minimizing unnecessary computational energy consumption.

Inventive Principle:
Principle #16Partial or excessive action
