Krohne Altosonic V12 – The answer to rising gas prices

30 January 2009

In a world of continually increasing energy prices, demand has grown for highly accurate and reliable flowmeters that can help end users take greater control of their process costs.

KROHNE has listened to the market and as a result has developed the ALTOSONIC V12 – a new generation of ultrasonic gas flowmeters for custody transfer applications.

The ALTOSONIC V12 has 12 measurement chords, two of which are dedicated solely to diagnostic functions, so once commissioned, the meter continuously checks the operating status. The positioning of the chords in five horizontal parallel planes compensates for swirl and therefore provides reliable measurement even with highly distorted flow profiles.

The diagnostics in the ALTOSONIC V12 reliably assess deposits, contamination or changes in wall roughness so that maintenance can be scheduled according to the actual needs of the user.

During the research and development phase of the ALTOSONIC V12, KROHNE found that there were two main areas of concern that customers were finding could not be satisfactorily addressed by ultrasonic flowmeters currently on the market:

Firstly, the issue of how to transfer the calibration curve obtained under ideal conditions in the high-pressure test rig, to the real-life measuring station with its headers, strainers, bent pipes, etc. had to be addressed. Hundreds of flow profiles in all kinds of applications were analysed as part of the product development, the result of which is that the ALTOSONIC V12 fully complies with the installation requirements of ISO17089 and AGA9 standards.

Secondly, KROHNE found that end users were becoming increasingly concerned about the accuracy of the meter after a certain period of operation and the effect this ultimately had on costs and billing. Therefore the next challenge was to address the self-monitoring of the flowmeter during operation. By applying the proven reflecting technique, KROHNE’s ALTOSONIC V12 is able to detect not only changes in the flow profile, but also changes in the cross sectional area. Through this, the meter is capable of assessing process changes that existing ultrasonic flow meters cannot even detect.

The ALTOSONIC V12 is available in sizes DN 100 – DN 600, with a maximum operating pressure of 150 bar. It is also compatible with commonly used protocols and can be seamlessly integrated into any existing infrastructure.
