The specter of leaks looms large in oil and gas production. With a digital leak detection system (LDS), oil and gas operators can get a warning the moment a leak begins. An LDS combines sensors and analytics to give a complete view of the pipeline infrastructure that can minimize risks, decrease product loss, and maintain profit margins. |

The high rate of false alarms in standard pipeline leak detection systems can force system operators to waste labor chasing down problems that don’t exist. In some instances, false alarms are so prevalent that operators in the field view the detection system as the boy who cried wolf and simply turn the system off. Fortunately, newer technology provides an alternative. |

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. |

Custody transfer measurement of LNG is traditionally based on tank-level readings, but in recent years dynamic measurement using flow meters has rapidly gained popularity. KROHNE recently released a solution to measure LNG quality directly during loading. The newer capability helps to avoid costly disputes once the vessel has departed, while eliminating human errors in data processing. |

Process measurement of hydrogen has been successfully done for years in chemical or petrochemical installations and measurement of CO2 has been done in the food & beverage industry. However, high-accuracy measurement of large flowing volumes using ultrasonic time of flight or Coriolis flow meters still creates unique challenges. Explore these technical challenges and the solutions that have been developed. |

Generating accurate flow measurements in bulk transfer situations such as pipelines is a critical, but often difficult, task that requires large-diameter meters. Older mechanical metering technology tends to drift over time, rendering it less accurate and reliable. By comparison, Coriolis meters have a distinct advantage because they directly measure mass flow — so they are not affected by changes in temperature or pressure, the factors that have an impact on volume. |
