The Servo Tank Gauge is highly suited for custody transfer applications due to its high accuracy, reliability, and compliance with international standards. Custody transfer involves the commercial transaction of bulk liquids such as crude oil, refined petroleum products, chemicals, and LNG, requiring precise level measurement and volume calculations.
Why is a Servo Tank Gauge Ideal for Custody Transfer?
✅ 1. High Accuracy & Precision
- Offers an accuracy of ±0.4 mm or better, crucial for financial transactions.
- Ensures compliance with OIML R85 and API MPMS standards for custody transfer.
✅ 2. Continuous & Reliable Level Measurement
- Uses a servo-driven displacer to measure liquid levels continuously.
- Can detect interface levels, density, and temperature variations, essential for compensation in volume calculations.
✅ 3. Compensation for Density & Temperature
- Measures product density in real-time, improving inventory accuracy.
- Works with temperature sensors to provide compensated volume readings.
✅ 4. Integration with Inventory & Control Systems
- Easily integrates with tank farm management systems (TFMS).
- Supports communication protocols like Modbus, HART, FOUNDATION Fieldbus, ensuring seamless data transmission for custody transfer records.
✅ 5. Suitable for a Wide Range of Liquids
- Works with crude oil, refined fuels, chemicals, and LNG.
- Handles floating roof, fixed roof, and cryogenic tanks.
