LNGmass D8LB – Coriolis Flowmeter for LNG Refueling

The Endress+Hauser LNGmass D8LB is a high-performance Coriolis flowmeter specifically designed for LNG refueling applications. It combines accurate mass flow measurement with a compact, robust design to deliver reliable performance under demanding cryogenic conditions.

With operation down to -196 °C, high measurement accuracy and integrated multivariable measurement, LNGmass D8LB is engineered for applications where measurement reliability, space efficiency and consistent performance are essential.

Built for Extreme Cryogenic Conditions

Measuring LNG is considerably more demanding than conventional liquid flow measurement. Extremely low temperatures and changing process conditions require a flowmeter specifically designed for cryogenic service.

LNGmass D8LB is built for this environment, supporting medium temperatures from -196 to +125 °C. Its specialized design provides dependable measurement performance throughout LNG storage, transfer and vehicle refueling processes.

High Accuracy Where Every Measurement Matters

For LNG refueling, measurement accuracy directly affects the quantity being transferred. LNGmass D8LB provides measurement accuracy of up to ±0.15%, making it a strong choice for applications requiring precise and repeatable LNG measurement.

The Coriolis principle measures mass flow directly and provides stable measurement without relying solely on volumetric calculations.

Compact Design for LNG Refueling Systems

LNG dispensers and refueling skids often have limited installation space. LNGmass D8LB addresses this challenge with a compact measuring system designed specifically for LNG applications.

The Coriolis measuring principle also eliminates the need for conventional upstream and downstream straight pipe runs, giving system designers greater flexibility when integrating the flowmeter into compact equipment.

More Measurement from One Device

LNGmass D8LB does more than measure flow. It can provide mass flow, volume flow, density, temperature and corrected volume flow from a single measuring point.

This integrated approach simplifies the measurement system while providing the process information needed for monitoring, control and LNG dispensing applications.

Designed for Reliable Long-Term Operation

The flowmeter uses a Coriolis measuring system with no moving parts, reducing mechanical wear and helping minimize maintenance requirements.

Its robust construction is designed to withstand the demanding conditions associated with cryogenic LNG service, while the transmitter supports Modbus RS485 communication for straightforward integration into dispensing equipment and control systems.

Why is LNGmass D8LB suitable for LNG refueling?

Unlike general-purpose flowmeters, LNGmass D8LB is specifically designed around the requirements of LNG refueling and cryogenic measurement. Its extremely low temperature capability, high accuracy and compact design make it well suited to LNG dispensers and fuel transfer systems.

Can LNGmass D8LB measure LNG at -196 °C?

Yes. The flowmeter supports medium temperatures down to -196 °C, allowing it to operate reliably in cryogenic LNG applications.

How accurate is LNGmass D8LB?

LNGmass D8LB provides measurement accuracy of up to ±0.15%, supporting precise and repeatable measurement during LNG transfer and refueling.

Does it need straight pipe runs?

No. The Coriolis measurement principle allows LNGmass D8LB to be installed without conventional inlet and outlet straight pipe runs, which is especially valuable when space is limited.

What information can the flowmeter measure?

The device can provide mass flow, volume flow, density, temperature and corrected volume flow, giving the system multiple important process variables from one measurement point.

Where is LNGmass D8LB typically used?

Typical applications include LNG vehicle refueling, LNG dispensers, cryogenic fuel transfer systems and LNG measurement skids, particularly where accurate measurement and compact installation are important.
