Measurement solutions for custody transfer and fiscal metering

Metering control systems

A custody transfer metering system is a critical component of the oil and gas industry used to measure and quantify the transfer of hydrocarbon products between parties. It ensures accurate measurement and accountability during the exchange of oil, gas, or refined products, typically between buyers and sellers or different entities within the supply chain. Custody transfer and fiscal metering systems play a pivotal role in determining the value, quantity, and quality of hydrocarbon products being transferred, and it is essential for commercial transactions and regulatory compliance.
