E&H D8LB Coriolis Mass flowmeter

Complete Technical Guide: E&H D8LB (LNG mass) Cryogenic Coriolis Mass Flowmeter for LNG Applications

In the rapidly evolving landscape of liquefied natural gas (LNG) infrastructure, precision measurement at cryogenic temperatures is not just a requirement—it is a critical safety and fiscal necessity. The E&H D8LB Coriolis mass flowmeter, part of the Endress+Hauser LNGmass family, is the world’s most compact flowmeter specifically designed for LNG dispensers and bunkering stations .

As a specialized supplier of precision process instrumentation, ST-YUKE CO., LIMITED offers the complete range of the D8LB series. This technical guide provides engineers, project managers, and procurement specialists with an in-depth analysis of the specifications, model variants, and ordering code logic for this specialized cryogenic flowmeter.

Introduction to the LNGmass D8LB Coriolis Flowmeter

The E&H D8LB is a dedicated Coriolis mass flowmeter engineered explicitly for liquefied natural gas (LNG) applications . Unlike standard flowmeters, the D8LB operates flawlessly at extreme cryogenic temperatures down to –196 °C (–321 °F), ensuring accurate custody transfer and process control during LNG refueling operations .

The device features an ultra-compact design—the smallest worldwide for its class—allowing installation in the most space-constrained dispenser environments without any upstream or downstream straight-run requirements . With no moving parts, the LNGmass D8LB is inherently maintenance-free, reducing total cost of ownership in demanding LNG service .

Key Technical Specifications

The D8LB series leverages the Coriolis measuring principle, which operates independently of fluid properties such as viscosity or density—a critical advantage when measuring cryogenic liquids with varying compositions. Below are the verified technical specifications from Endress+Hauser documentation :

Full Model Range: The D8LB Series by Nominal Diameter

The D8LB series is classified into three primary nominal diameter variants, allowing precise matching to your LNG flow requirements. ST-YUKE CO., LIMITED stocks and supplies all the following configurations:

D8LB08 (DN 08 / 3/8″) – For micro-LNG flows and small-scale dispensing applications .

D8LB15 (DN 15 / 1/2″) – The standard size for typical LNG vehicle dispensing .

D8LB25 (DN 25 / 1″) – For high-capacity LNG bunkering and bulk transfer operations .
