LPG LNG Density Meter Inline

Short Description:

Process Density Measurement

The Inline LPG/LNG Density Meter enables continuous, real-time density monitoring directly in pipelines—eliminating inefficient offline sampling. Engineered for precision, it delivers reliable readings even in LNG’s cryogenic temperatures and LPG’s dynamic pressure conditions, with corrosion-resistant, rugged construction built to withstand harsh fuel-handling environments. Seamlessly integrable into existing storage, transport, or processing systems, it empowers operators to optimize fuel quality, enhance operational efficiency, and maintain safety compliance.

    Product Tags

    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.
