SISCO ultrasonic fuel level transmitter is designed for accurate non-contact fuel level monitoring in tanks and storage systems. It supports stable operation in harsh environments, with an instrument temperature range of -20°C to 60°C and a probe temperature range up to 80°C. The compact 500 g design and 10%–85% humidity tolerance make it suitable for diesel tanks, oil storage, and industrial fuel management systems.
Superior Measuring Performance & Measurement Accuracy
- High Resolution & Fast Response: With <3 mm resolution and a minimum response time of 2 seconds, this ultrasonic fuel level sensor quickly detects liquid level changes.
- Intelligent Ultrasonic Probe: Multi-point signal transmission technology reduces errors caused by single-point emission, improving measurement stability in complex industrial environments.
- Automatic Temperature Compensation: The ultrasonic fuel level sensor automatically adjusts sound velocity according to temperature changes, reducing measurement errors and maintaining consistent accuracy.
- Echo Curve Visualization: Real-time echo signal monitoring helps technicians complete on-site setup and identify interference sources.
User-friendly Operation & Robust Hardware Protection
- Optimized Human-Machine Interaction: Equipped with a high-definition LCD supporting Chinese & English bilingual menus. The 4-key intelligent control panel enables intuitive, smooth parameter configuration for operators.
- IP68 High Protection Grade for Probe: The ultrasonic level transmitter probe reaches an IP68 waterproof and dustproof rating. Maintenance-free design ensures continuous stable service for over 5 years, perfectly suitable for outdoor, humid, and dusty industrial environments.

Q1: How does an ultrasonic fuel level sensor improve fuel tank management?
A1: An ultrasonic fuel level sensor improves fuel tank management by providing real-time level information without manual inspection. It helps users monitor fuel usage, schedule refilling, reduce downtime, and improve efficiency in industrial fuel storage systems.
Q2: Is an ultrasonic fuel level transmitter safe for fuel monitoring?
A2: Yes. Since the ultrasonic level transmitter does not directly contact the fuel, it reduces risks related to corrosion, contamination, and mechanical failure. Proper installation and selecting a suitable model are important for safe operation.
Q3: Can an ultrasonic fuel level sensor monitor fuel consumption?
A3: Yes. When connected to a monitoring system, an ultrasonic fuel level sensor can track fuel level changes over time, helping users analyze fuel consumption and manage refueling schedules.
Tips: Can an ultrasonic fuel level sensor be used for diesel generator fuel tanks?
Yes, an ultrasonic fuel level sensor can be used for diesel generator fuel tanks to provide continuous and accurate fuel level monitoring. Its non-contact measurement design avoids direct contact with diesel, reducing maintenance and preventing sensor wear. It helps users track fuel levels in real time, schedule refilling, and reduce the risk of unexpected generator shutdowns caused by low fuel.
