This publication integrates these stand

41、ards, by reference, into a framework that may be applied during custody transfer of crude oil from lease tanks to a tank truck without requiring direct access to the tank thief gauge hatch. Many of the individual standards have guidelines defining the frequency and tolerances for installation, verif

42、ication, and calibration of the specified equipment under controlled or ideal conditions allowing for uncertainty within custody transfer requirements. However, with the conditions encountered in many of todays applications, the installation, verification, and calibration of measurement devices may

43、have higher uncertainties due to the operational characteristics and limited access available at the lease site. In the interest of safety and environmental concerns, these higher uncertainties may still provide acceptable measurement for custody transfer of crude oil from tanks using the defined al

44、ternate methods. The alternate measurement methods discussed in this standard are intended to minimize uncertainty and bias while encouraging consistent measurement and testing practices using existing technologies within API standards that are available at the time of the development of this standa

45、rd. They are not intended to interfere with business contracts, existing API standards, or the development of new technologies or to comprise the only acceptable alternate methods of custody transfer of crude oil by trucks. Custody Transfer of Crude Oil from Lease Tanks Using Alternative Measurement

46、 Methods 1 Scope This standard defines the minimum equipment and methods used to determine the quantity and quality of crude oil being loaded from a lease tank to a truck trailer without requiring direct access to a lease tank gauge hatch. Methods and equipment described are grouped by tank zone, tr

47、ailer zone, and the transition zone between the two (see Section 5). The equipment used for measurement is dependent on the existing design of the lease equipment, the equipment used to transport the product, or a combination of the two. Some sites may require measurements from multiple zones in ord

48、er to arrive at an accurate load quantity and quality. 2 Normative References The following referenced documents are indispensable for the application of this document.
