Metering stations are facilities used to measure the flow and quality of various substances, such as natural gas or liquids, in pipelines. They play a crucial role in monitoring the amount of product being transported, ensuring accurate billing, and maintaining safety standards. These stations typically include equipment like flow meters, pressure gauges, and sampling devices. By collecting data on the flow rate and composition, metering stations help operators manage resources efficiently and comply with regulatory requirements, contributing to the overall reliability of the pipeline system.
