Ms. Sherry Sheckels has performed volume and density calibrations at NIST since 2000. In this work, she has calibrated a variety of volumetric test measures, including slicker plate type and standard volume test measures with nominal volumes from 1 gallon to 1500 gallons. She is active with the American Petroleum Institute representing NIST at the spring and fall meetings. She also performs hydrometer calibrations. Ms. Sheckels is also conducts liquid flow calibrations in the Fluid Metrology Group. She calibrates flow meters up to 2 inches in size using the 0.1 L per sec liquid flow standard and the 2.5 L per sec liquid flow standard.
