Automated Substitution Weighing Apparatus for Liquid Volume Measurement

June 26, 2019
Author(s)
John D. Wright, Sherry D. Sheckels, Joey T. Boyd
The custody transfer of petroleum worth $1 × 10 12 / year is traced to the volume delivered from provers and liquid test measures. Mistakes as small as 0.02 % in a custody meter calibration can lead to multi-million dollar corrections in bills. NIST

Tests of the Extended Lee Model Using Three Different Turbine Meters

June 20, 2012
Author(s)
Jodie G. Pope, John D. Wright, Sherry D. Sheckels
We report additional tests of our “extended Lee model” for calibrating turbine meters. The model accounts for 1) Reynolds number (Re) dependent drag and lift, 2) bearing static drag and 3) bearing viscous drag. Initially, we tested this model using a dual

NIST Calibration Services for Liquid Volume

November 24, 2009
Author(s)
Vern E. Bean, Pedro I. Espina, John D. Wright, J F. Houser, Sherry D. Sheckels, Aaron N. Johnson
NIST provides calibration services for metal volume provers for liquid volumes from 4 L to 7600 L using gravimetric and volumetric methods. This document describes the procedures and methods of calculation used in the calibration service. The covered
