What are the advantages and disadvantages of ultrasonic flow meter gas flow measurement?


#1

Advantages of ultrasonic flow meter for Gas flow measurement

1.High Accuracy
2.Approved for custody transfer
3.High turndown/rangeability measure low and high pressure
4.Repeatable
5.Can clamp on pipe with no penetration
6.Tolerate extreme temperature
7.Long term reliability
8.No moving parts to replace or lubricate.So low maintenance cost

Disadvantages of ultrasonic flow meter for gas flow measurement

1.High initial cost
2.Dirt and fluid impact performance and measurement accuracy
3.Noise even beyond human hearing range interfere with ultrasonic signals for clamp-on meter
4.Pipe walls can interfere with ultrasonic signals for clamp-on meter.
5.Build-up on the inside pipe walls can reduce inside diameter of pipe and affect measurement accuracy
