Ultrasonic and Coriolis flow meters are generally the most accurate technologies to support pipeline leak detection systems, which is critical because the better the metering, the better the detection sensitivity.
Ultrasonic flow meters — which rely on high-frequency sound waves for more precise readings — are ideal for a variety of applications because they don’t have moving parts and are not subject to drift over time. However, these meters measure fluid velocity, so they strongly depend on a known cross-sectional meter area for volumetric flow metering.
Oil and gas companies rely on accurate flow measurement anywhere that hydrocarbons are being stored — including terminals and loading/offloading facilities — as well as upstream, where crude oil is pulled from the ground and small amounts of gas byproduct are commonly flared.
As the sheer number of pipelines crisscrossing the country continues to increase, there is an urgent need to ensure pipeline infrastructure safety. Now, new technology has been developed that meets the need for reliable protection that complies with regulatory requirements while eliminating false alarms.
