LNG Coriolis Mass Flow Meter | ±0.1% Cryogenic Accuracy

CMASS025LD LNG Coriolis mass flowmeter

1. Enables Accurate Trade Settlement and Prevents Financial Loss

This flow meter delivers unparalleled accuracy (typically up to 0.1%) and directly measures mass flow (kg/h), the internationally recognized standard for LNG trade settlement. It provides the sole, trustworthy measurement basis for both buyers and sellers, completely eliminating financial risks and disputes caused by inaccurate metering.

2. Enhances Process Control and Ensures Production Safety

Real-time, accurate flow data serves as the foundation for DCS/SIS systems to execute equipment interlocking, load adjustment, and tank farm management. Precise control prevents safety hazards such as equipment overload or tank overfilling, ensuring stable and safe operation of the entire facility.

3. Enables Precise Energy Management and Cost Reduction

Provides precise cumulative mass data (in tons or kilograms), enabling enterprises to implement detailed energy management, accurately calculate costs and revenues, and optimize operational strategies.

4. Ensures Compliance with Regulations and Standards, Safeguarding Project Legitimacy

Cryogenic Coriolis flow meters are often the preferred solution to meet these stringent regulatory and certification requirements (such as ATEX explosion-proof and SIL safety ratings), ensuring full compliance and legal integrity for projects.

Key advantages of applying it to liquefied natural gas operating conditions

1. Direct Mass Flow Measurement Without Conversion

This is the core strength of the Coriolis principle. LNG is a cryogenic liquid whose volume fluctuates significantly with minor changes in temperature and pressure. Traditional volumetric flow meters (e.g., turbine, vortex) require complex temperature and pressure compensation systems, and any errors in compensation models are amplified.

2. Structure and Materials Designed for Cryogenic Service

Uses stainless steel or alloy steel with exceptional low-temperature toughness to prevent cold embrittlement. Employs specialized low-temperature sealing materials (e.g., PTFE, metal bellows seals) to ensure leak-proof reliability. Typically features insulation jacket ports for external insulation, preventing cold loss and ice formation that could compromise electronic components.

4. Multi-Parameter Measurement Capability

Advantage: While measuring mass flow, it simultaneously monitors the density and temperature of LNG.

Typical Application Scenarios

• Unloading measurement and tank turnover at LNG receiving terminals
• Large-scale vehicle or ship bunkering at LNG refueling stations
• Custody transfer and trade measurement at liquefaction plants
• Leak detection and inventory management in cryogenic storage tanks
• Flow control of cryogenic media (e.g., liquid nitrogen, liquid oxygen) in chemical processes
