The CEESI videos showed liquid entrained downstream in the recirculation area.
Therefore, NIST itself is responsible for the calibration of the large working standard turbine meters at CEESI.

"The bulk of our calibrations so far have been ultrasonics," notes Steve Caldwell, CEESI Vice President.
The latest research results are then presented annually at CEESI flow measurement workshops and conferences around the world.
A graduate of California State Polytechnic Institute-Pomona where he would eventually earn his BS in mechanical engineering, he joined CEESI in August 2012.
In 1999, CEESI set out to quantify two-phase flow measurement errors by building a wet gas test facility (WGTF).
CEESI has been actively monitoring and analyzing ultrasonic meter calibration results for a variety of purposes, including assessment of recalibration intervals.

The following independent data is from API 22.1 testing that was performed at the CEESI facility in 2011.
Figure 2 shows a 4-inch, 0.45 beta ratio cone meter being calibrated with natural gas flow at CEESI. This meter was previously calibrated with water at lower Reynolds numbers at the manufacturer's facility.
Figure 1 shows a 4-inch, 0.6 beta ratio dual chamber orifice meter at the CEESI wet gas flow test facility.
