In the high-stakes world of Liquefied Natural Gas (LNG) transactions, even a 0.1% measurement error can result in millions of dollars in financial discrepancies. The FLOWSIC900 is a specialized ultrasonic flowmeter engineered specifically for the extreme cryogenic demands of the LNG industry—from liquefaction plants to offshore floating storage (FSRU) and transport.

Financial Risk Mitigation: Certified to OIML R117 Class 0.3, the FLOWSIC900 provides the world's highest measurement certainty, ensuring fair and accurate billing for large-scale LNG shipments.
Superior Energy Efficiency: Traditional meters cause pressure drops that lead to expensive boil-off losses. The FLOWSIC900's wide-open path ensures zero pressure-induced BOG, maximizing your liquid recovery.
Cryogenic-Ready Installation: Unlike other meters requiring complex on-site insulation, the Flare-XT comes factory pre-insulated. This drastically reduces installation time and prevents thermal leakage.
Intelligent Digital Diagnostics: Continuously monitors gas quality and meter health via Speed of Sound (SoS) tracking, allowing for predictive maintenance without interrupting the flow.
Hanyu Supply Reliability: We ensure compliant technical selection and specialized global logistics for large-bore instrumentation, keeping your LNG terminal projects on track.
The Challenge: An LNG import terminal required a maintenance-free ship-to-shore measurement solution that would not trigger pressure-induced boil-off during high-volume unloading.
The Hanyu Solution: We provided the FLOWSIC900 with a remote SPU configuration.
The Result: The terminal achieved real-time transparency during unloading with the lowest possible uncertainty.
The Impact: The full-bore design effectively minimized BOG losses, saving the operator significant product volume per shipment. Technicians now monitor data safely from the control room, far from the cryogenic hazard zones.
Q1: How does FLOWSIC900 maintain accuracy at -162°C?
A: The meter utilizes advanced ultrasonic transducers specifically designed for cryogenic fluids. Combined with factory-applied thermal insulation, it prevents thermal gradients that could affect the speed of sound and measurement stability.
Q2: Does zero pressure drop really save money?
A: Yes. In LNG transfer, pressure drops lead to localized heating and "flashing" (liquid turning to gas). By maintaining a zero pressure drop, the FLOWSIC900 minimizes BOG formation, ensuring more of your product stays in liquid form.
Q3: Can Hanyu Zhilian support technical selection for large-bore LNG projects?
A: Absolutely. Through
đĄ System Integration Tip:
For maximum custody transfer precision and MID/OIML compliance, the FLOWSIC series is ideally paired with the [SICK Flow-X High-Precision Flow Computer]. To ensure stable pressure compensation for fiscal measurement, we also recommend integrating the [Rosemount 3051S Pressure Transmitter] as part of our high-end integrated solutions.
