Custody Transfer Systems encompass a wide range of processes, including pipeline metering/loading, unloading/trans-loading of rail cars, tanker trucks, barges, ships, and tank farms. These systems play a pivotal role when ownership of a product transitions from one entity to another. The terms “Fiscal Metering” and “Custody Transfer” are often used interchangeably, with Fiscal Metering referring specifically to the transfer phase and Custody Transfer referring to the broader system or solution.

At the heart of Custody Transfer Solutions lies the flow measuring device, commonly known as the “flow meter.” This device captures and records data concerning the volume of product being exchanged between the buyer and seller, often likened to the cash register of the Oil & Gas industry.

While a variety of flow meters are available, selecting the appropriate one for a specific custody transfer application is crucial. The wrong choice can lead to operational difficulties and jeopardize the accuracy of the Custody Transfer System. Precision is of utmost importance due to the stringent accuracy requirements. Therefore, careful consideration is essential when designing a Custody Transfer System tailored to each unique application.

To ensure compliance with Custody Transfer requirements, all complete pumping systems must adhere to governing body regulations such as ISO, API, AGA, and metrology standards like NIST, GOST, OIML, ONML, PTB, and CMC. Two primary approaches are commonly taken when handling Custody Transfer: contractual agreements between buyers and sellers for large-volume transfers and legal metrology traceable from Weights and Measures.
