In my opinion you may refer following stds.
API 2531 – Mechanical Displacement Meter Proves – 1st Edition 1963.

API 2534 - Manual of Petroleum Measure Standards Chapter 5 – Liquid Metering – Section 4 Accessory Equipment for Liquid Meters – 2nd Edition 1987.

API 2534 - Manual of Petroleum Measure Standards Chapter 5 – Metering – Section 5 Fidelity and Security of Flow Measurement Pulsed-Data Transmission Systems – 1st Edition 1992.

API 2534 - Manual of Petroleum Measure Standards Chapter 6 – Metering Assemblies – Section 7 Metering Viscous Hydrocarbons – 2nd Edition 1991.

API 2551 - Method for Measurement and Calibration of Horizontal Tanks – 1st Edition 1965.

API 2552 - Method for Measurement and Calibration of Spheres and Spheroids – 1st Edition 1965.

API 2554 - Method for Measurement and Calibration of Tank Cars – 1st Edition 1965.

API 2555 - Method for Liquid Calibration of Tanks – 1st Edition 1966.

API 2556 - Correction Gauge Tables for Incrustation – 2nd Edition 1993.

If you have any other idea do share.
