ALTOSONIC V12
Ultrasonic gas owmeter for custody transfer
As times change, so do the requirements for ultrasonic meters. Today it is assumed that an ultrasonic device
measures accurately and precisely, but what about long-term reliability? After all, this depends on more
than just the ultrasonic meter itself. The transferred effect of the high pressure calibration on the installation
conditions in the measuring station and dirt, which may collect on the meter over time, can also have a
negative effect.
The unique chord arrangement of the ALTOSONIC V12 enables it to generate diagnostic data for places
where traditional ultrasonic meters gathered too little information or none at all: rstly at the pipe wall itself,
scanning with reection. Secondly, in close proximity to the pipe wall, using the geometrical arrangement of
the outer chords. Thirdly, at the bottom of the pipe. This data is gathered using a separate diagnostic chord.
This extremely extensive diagnostic data allows the ALTOSONIC V12 to carry out self-monitoring, which sets
the standard for other devices in terms of performance monitoring.
Highlights
• 12-chord design
• High reliability with built-in redundancy
• Swirl compensation in each measuring plane
• Transducer replacement under pressure
• Bi-directional ow measurement
• Fully encapsulated cabling
• Field display for main functions
Industries
• Oil & Gas
• Petrochemical
Applications
• Offshore FPSO and platforms
• Onshore exploration
• Transmission
• Underground gas storage (UGS)
• Distribution
• Large gas intakes, for example for
power stations, petrochemical industry,
aluminum smelters, etc.

Inlet / outlet run requirements
Without Flow Conditioner
With KROHNE Flow Conditioner
ALTOSONIC V12
Under specic conditions ALTOSONIC V12 can be installed with just 5D
and no ow conditioner, please consult KROHNE if this option is required.
Where traditional ultrasonic ow meters typically require 10D straight inlet piping with a ow conditioner or
20D without a ow conditioner, ALTOSONIC V12 only requires 5D with ow conditioner or 10D without ow
conditioner. This not only minimizes the weight and footprint of the installation, but also saves on installation- and shipping costs, both during new installation as well as during re-calibration.
This much shorter installation length permits planning of more compact new metering runs and slot-in
replacement of conventional meters such as turbines during revamps.
