Ultrasonic gas flowmeters for custody transfer applications.
With the Altosonic V12 Krohne has launched the next generation of accurate ultrasonic gas flowmeters for custody transfer applications.
The flowmeter has 12 measuring chords, two of which are solely dedicated to diagnostic functions. Once commissioned, it continuously checks the operating status. The positioning of the chords in five horizontal parallel planes compensates for swirl and thus provides reliable measurements even with highly distorted flow profiles.
The diagnostics in Altosonic V12 reliably assess deposits, contamination or changes in wall roughness so that maintenance can be scheduled according to the actual needs.
During product development Krohne focused on two significant problems that customers encounter and which were not satisfactorily addressed by existing ultrasonic flowmeters:
* The first challenge was 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. In order to solve this, hundreds of flow profiles in all kinds of applications were analysed. This has resulted in an ultrasonic flowmeter capable of complying with the ISO17089 and AGA9 standards having 5D straight inlet requirements without using a flow straightener.
* The second challenge concerned self-monitoring of the flowmeter during operation. In other words, how accurate is billing going to be after a certain period of operation? Applying the proven reflecting technique, the meter is able to detect not only changes in the flow profile, but also the changes in the cross sectional area.
The meter is available in sizes DN 100 – DN 600, an installation length of 3D, and a maximum operating pressure of 150 bar. It is compatible with commonly used protocols and can be seamlessly integrated into any existing infrastructure.

Editor's Choice Flow Measurement & Control
There are many processes where it is undesirable for the load to suddenly change quickly, for example in the paper industry. Examples of level control have involved reasonably fast tuning. An example of a level loop tuned this way and responding to a step change in setpoint is given.
