Ultrasonic flowmeters for Caspian oil
pipeline
Ultrasonic flowmeters from Krohne are playing a key role in maintaining the flow of oil from one of the world's richest oil fields in Kazakhstan
The 1500km Caspian Pipeline, built by the multinational Caspian pipeline Consortium (CPC) was officially opened in November 2001 to carry oil from Kazakhstan to Russia The USD2.3 billion pipeline has an initial capacity of 28 million tons of crude oil per year (600,000 barrels per day)

The oil is carried from the huge Tengiz oil field in Kazakhstan, around the coast of the Caspian Sea and across southern Russia to the port of Novorossiysk where the largest oil terminal in Russia has been constructed.
The majority of the UFM 500 twin beam ultrasonic flowmeters are of large diameters from 40 up to 56inches.
Fifteen have been installed in the Russian section of the pipeline, a further five in the section within Kazakhstan, and four, including two 56inch UFMs, are in use at the marine terminal.
Pressure drop caused by intrusive flowmeters such as PD or turbine units is a vital consideration on long distance pipelines.
Krohne UFMs offer 'zero pressure drop' which means less powerful pumps can be used, thereby saving on energy costs and resulting in higher flow rates.
The Krohne units are also virtually maintenance free with no moving parts to wear; another key factor as the pipeline stretches across many areas that are difficult to access.
To eliminate potentially hazardous leakage at the flanges, the UFM 500s were built without flanges and welded directly to the pipeline itself.
Krohne also equipped the piezo sensors on each UFM with heating elements which are constantly heated at a temperature above the pour point of wax in order to remove the wax and paraffin deposits which can lodge in cavities after the passage of the 'pig' in the pipeline.
