Ultrasonic flow meters are advanced instruments that measure the flow rate of liquids or gases by using high-frequency sound waves. They are widely used in the oil and gas industry, especially for custody transfer, pipeline monitoring, and process control, due to their non-intrusive nature, high accuracy, and low maintenance requirements.

 

Custody transfer grade meters range from ±0.1% to ±0.5% in accuracy and they operate exceptionally well in clean, pre-conditioned flow.
