KROHNE flow metering systems are used throughout the entire natural gas value chain, from high pressure production of (wet) gas throughout all refining operations, and down to city gates that deliver natural gas to local gas grids. Specifically for custody transfer metering (CT) of LNG at cryogenic temperatures, KROHNE developed a metering solution to measure both the volume and quality of LNG. With the first ultrasonic flowmeter for custody transfer LNG measurement released in 2007, KROHNE has over 10 years experience with high accuracy measurement under cryogenic conditions.
KROHNE takes full project responsibility for the system, including metering skids with instrumentation, gas chromatographs and analysers, flow computers, metering control cabinets and all supervisory and validation software. KROHNE LNG metering systems can be designed as a master-duty configuration, where a Z-cross over allows periodical verification of the duty meters against a master meter. The diagnostic features of the flowmeters are used to guarantee maximum performance and lowest measurement uncertainty of the system.
With instrumentation, metering and supervisory system from the same source, customers can rely on seamless integration of all components. KROHNE is established in the Oil & Gas industry since 1921 and has a local presence in over 100 countries to provide on-going support.
