Background of Ultrasonic Meter Use

elster instromet ultrasonic flowmetersSince AGA Report No. 9 in 1998, multipath ultrasonic gas flow meters have become the primary method for measuring flow in large pipelines, particularly for the custody transfer of natural gas. The meter has excellent measurement accuracy, high turndown, good resistance to installation effects, and cost-effectiveness and is found throughout the natural gas network, from gathering, transmission, and distribution.

Working Principle and Benefits

Ultrasonic meters measure the velocity of the gas within the meter’s body. By knowing the velocity and cross-sectional area, the uncorrected volume is computed.

The gas flow meter uses sound waves to establish the velocity of a gas flowing in a pipe. At no-flow conditions, the frequencies of an ultrasonic wave transmitted into a pipe and its reflections are the same. Whereas, when gas flows, the frequency of the reflected wave changes because of the Doppler effect. When gas moves faster, the frequency shift increases linearly. The meter’s transmitter processes the signals from the transmitted waves and their reflections to determine the gas flow rate.

  • High rangeability (typically > than 50-1)
  • High accuracy and very linear
  • No moving parts
  • Ability to measure bi-directional flow
  • No pressure drop
  • Reliable with dirty gas
