LPG LNG Density Meter Inline
LONNMETER-U600 is a high-precision Coriolis mass flow meter for liquids and gases. In addition to the flow, U600 also directly measures the fluid density. The U600 Coriolis flow meter was developed for applications where maximum accuracy, a huge measuring range and highest process reliability are required. LONNMETER-U600 has a variety of analog and digital interfaces and can therefore be easily integrated into existing PLC. U600 is very easy to use. Thanks to the large graphical display, the flow meter can be easily set up using the front buttons or with the included IR remote control. The LONNMETER-U600 flow meters performs with high accuracy for optional corrosion-resistant materials like Hastelloy, Titan, Tantal, Duplex S.S.. etc. The mass flow of liquids is measured in a huge span with the class 0.2%,0.1% or 0.05%. The density is determined with an uncertainty of 0.1 - 0.5 g/l. resistant steels, U600 is suitable for a variety of fluids.

Features
• Multivariable integrated measurement: Simultaneously captures mass flow, density, and temperature in a single device, eliminating the need for multiple separate sensors.
• Dual-medium applicability: Supports flow and density measurement for both liquids and gases, making it versatile for LPG/LNG and other fluid handling scenarios.
• High-precision performance: Delivers typical accuracy of 0.05–0.2% for liquids and 0.2–0.5% for gases, ensuring reliable data for quality control and operational optimization.
• Extreme condition tolerance: Engineered to operate stably under extreme temperature and pressure, adapting to the harsh environments of LPG/LNG storage, transport, and processing.
• Simplified installation: Requires no dedicated inlet or outlet, reducing setup complexity and minimizing operational downtime during integration.
• Flexible measurement option: Offers an optional bi-directional measurement function, accommodating diverse pipeline flow directions for broader application flexibility.
Applications
Coriolis flow meters excel in scenarios demanding high accuracy and reliable measurement—making them a go-to solution across multiple industries:
-
Industry-Specific Metering Tasks:
• Food industry: Precision dosing for ingredients, fruit concentrates, juices, and beer (ensuring consistency and compliance with food safety standards).
• Chemical & pharmaceutical sectors: Stable measurement for process fluids, cosmetics, and solvents (supporting strict quality control in sensitive production).
• Hydrocarbon industries: Additive dosing in fuel processing, plus dedicated measurement for liquefied gases (e.g., LPG/LNG) and oils/fats (aligning with energy sector operational needs).
-
Custody Transfer Processes:
• Ideal for applications requiring traceable, accurate measurement for trade-related fluid transfer (e.g., fuels, industrial chemicals), meeting regulatory and commercial accountability standards.
-
Broad Medium Compatibility:
• Effectively measures a wide range of substances, including detergents, alcohol, various gases, and liquefied gases—adapting to both liquid and gaseous fluid handling requirements.
