Overview

KROHNE metering systems are used throughout the entire oil & gas value chain – from allocation measurement during oil production up to truck and train loading of refined products at the refinery – to guarantee an exact measurement. Also the downstream consumers of HFO or LFO like power plants make use of our metering systems. KROHNE takes full project responsibility for the system, including metering skids, analysers, and flow computers integrated into the metering control cabinet, with all supervisory and validation software.

KROHNE metering systems are often designed as a master-duty configuration, where a Z-cross over allows periodical verification of the duty meters against the master meter. This set-up reduces costs, weight and footprint - as a high-end bulky prover is no longer required. KROHNE can offer a range of mobile and ball provers for custody transfer metering, in cases where an on-site prover is still requested. With instrumentation and metering system design from the same source, flow measurement relies 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.
