The Micro Motion New Generation LNG Dispenser System is the most advanced measurement package available for the global LNG refueling market. By integrating both the liquid delivery meter and the gas return (BOG) meter into a single transmitter, it offers a streamlined, complete solution in one compact package.

Integrated 2-in-1 Solution: Eliminates the need for separate transmitters for filling and vapor return. This integration simplifies dispenser design, reduces costs, and provides a unified data output for the dispenser’s controller.
Cryogenic Mastery: Rated down to -196°C (-320°F), the system handles the unique challenges of liquid natural gas, including rapid cool-down cycles and extreme temperature gradients.
Two-Phase Flow Excellence: Advanced MVD (Multivariable Digital) technology excels in managing entrained gas during the start of the fueling cycle, ensuring batch accuracy remains within ±0.5%.
Simplified "Plug & Play" Wiring: Features high-durability aviation plug joints and a built-in safety barrier. This reduces wiring errors during assembly and improves long-term reliability in vibrating dispenser cabinets.
Compact Footprint: Engineered to save critical installation space inside narrow dispenser housings, allowing for easier maintenance access and more efficient skid layouts.
Custody Transfer Approved: Third-party certified performance ensures compliance with local metrology requirements (MID, NTEP, OIML), making it ready for global commercial use.
Zero Maintenance: No moving parts to wear out or replace, ensuring repeatable measurement for years without the drift associated with mechanical meters.
Enhanced Durability: Aviation-grade connectors resist moisture ingress and the constant vibration of high-traffic refueling stations.
Total Inventory Control: By measuring both the liquid delivered and the gas returned to the tank, operators get a true "net" delivery figure for better inventory management.
The Challenge: An LNG dispenser OEM struggled with complex internal wiring and inconsistent accuracy during the initial "flash" phase of fueling when gas and liquid are mixed.
The Hanyu Solution: They adopted the Micro Motion New Generation LNG Dispenser System from
The Result: The 2-in-1 transmitter reduced internal cabinet wiring by 50%. The system's ability to handle two-phase flow ensured the batch accuracy stayed well within the ±0.5% legal limit.
The Impact: Dispenser assembly time was reduced by 3 hours per unit, and the end-user reported 100% reliability in billing, even during high-temperature ambient conditions.
Q: Does one transmitter really handle two different flow streams?
A: Yes. The dual-core processor is designed to independently process signals from both the liquid sensor and the gas return sensor simultaneously, outputting data for both.
Q: Is this system compatible with all LNG dispenser controllers?
A: The system is designed to be highly compatible with standard industrial protocols. We recommend pairing it with the latest Emerson transmitters for the best integration.
Q: How does it handle the start of the fueling process?
A: It uses specialized algorithms to filter out the noise caused by two-phase flow (gas/liquid mix) that typically occurs when the hose is first chilled, ensuring the batch total remains accurate.
