Q.Sonic-max

What Is It?
Since the publication of the AGA Report No. 9 in 1998, multipath ultrasonic flow meters have become the dominant method for measuring flow in large pipelines, particularly for the purpose of custody transfer of natural gas. There are many reasons for this trend – excellent measurement accuracy, high turndown, good resistance to installation effects, and cost effectiveness.
As good as these meters may be, like all meters they can still be affected by the conditions in which they are placed. In particular, the design of the upstream pipework and its operating conditions determine the velocity profile of the fluid as it passes through the meter. In order to minimize this installation effect, the Q.Sonicmax, meets and exceeds the OIML Accuracy Class 0.5.
 
How Does It Work?
The Honeywell Q.Sonicmax USM is the first 8-path meter to combine reflection paths with direct paths, which results in detailed flow profile recognition with superb noise immunity. Due to this unique patented path configuration, the device offers the lowest uncertainty possible with the most extended diagnostics capabilities. The reflective paths with their sophisticated diagnostics mean the meter quickly identifies swirl, fouling or liquids inside the meter. The direct paths provide enhanced robustness for higher valve noise immunity and CO2-rich applications.
Internal pressure and temperature sensors ensure accurate calculation of the Reynolds number and dynamic correction of the meter body. It offers unequalled flow profile recognition and maintains the lowest uncertainty in all situations.  
 
What Problems Does It Solve?
Market leading ultrasonic metering technology, advanced diagnostics and easy-to-use software deliver the highest levels of accuracy, confidence, cost-effectiveness and long-term reliability. The Q.Sonicmax offers unequalled flow profile recognition and maintains the lowest uncertainty in all situations. No deviations from the standard or restricted flow rates have had to be accepted in order to  comply with OIML Accuracy Class 0.5 .
