Background
Before implementing a tank monitoring system, most plantation companies checked fuel stock manually — using dipstick measurements or visual inspection. This approach created persistent problems: inaccurate data, delayed information, and an ongoing risk of fuel loss or misuse.
For a rubber plantation operation in Medan, North Sumatra, fuel is a critical operational resource spread across a wide estate area. Without automated monitoring, stock levels were never fully visible in real time, reorder decisions were reactive, and there was no reliable history of consumption to support planning or audits.
PT Phase Delta Control was engaged to deploy an Automatic Tank Gauge (ATG) system — a high-precision level sensor solution that measures fuel volume automatically and continuously, replacing manual checks with live, accurate data accessible from a web-based platform.
System Requirement
Provide real-time fuel stock data across all tanks without manual checks
Eliminate operator time spent on manual dipstick measurement
Reduce the risk of stock recording errors
Detect fuel loss or leakage automatically
Trigger timely fuel reorder before stock runs critically low
Maintain a complete history of fuel consumption across all tanks
Support fuel stock audits and reconciliation with accurate records
Project Implementation
Component | Function |
|---|---|
ATG Sensor | Mounted on top of each fuel tank — measures fuel volume continuously with high precision |
Communication Network | Transmits sensor readings from tanks to the monitoring system |
Monitoring Server | Processes incoming measurements and converts raw data into readable stock figures |
Web-based Dashboard | Displays live stock levels, consumption trends, and automatic alarms from any workstation |
System Description
ATG sensors are mounted at the top of each fuel tank and measure conditions inside the tank continuously. Readings are transmitted to the monitoring system through a communication network, where raw sensor data is converted into clear, readable information — fuel stock volume, consumption rate, and remaining capacity.
The system monitors all tanks simultaneously, giving operators and managers a single live view of stock levels across the entire plantation estate. When a reading crosses a configured threshold — a low-stock level or an anomalous drop that may indicate leakage — the system raises an automatic alarm, enabling the team to respond before the situation affects operations.
All measurements are logged continuously, building a complete historical record of fuel consumption that supports procurement planning, audit reconciliation, and regulatory reporting.
Summary
The ATG system replaced manual dipstick checks with continuous, automated fuel stock monitoring across the plantation estate. Stock levels that had previously depended on operator visits and handwritten records became instantly visible, automatically alarmed, and fully logged — giving the company accurate data to manage fuel more efficiently and reduce losses.
Key Outcomes:
Real-time stock monitoring across all fuel tanks — no manual checks required
Fuel loss risk reduced through automatic anomaly detection and alerts
Data accuracy improved by eliminating manual measurement and recording
Fuel procurement planning supported by live consumption data and trend history
Audit and reporting simplified with complete, automatically generated records
Operational efficiency improved across the estate
Digital transformation of plantation fuel asset management
