Abstract
NIST and other laboratories calibrate meters that measure the flow of valuable liquids such as petroleum products. Historically, these calibrations have been conducted using Stoddard solvent. Laboratories using Stoddard solvent for liquid-flow calibrations must contend with flammability, inhalation toxicity, and hazardous waste disposal requirements. In response to these health and safety concerns, we modified NISTs piston-prover flow standards so that calibrations are now conducted with mixtures of propylene glycol and water (PG + W). In this paper, we describe the modifications to NISTs calibration systems and our experiences in using the modified systems to calibrate turbine, positive displacement, and coriolis meters.Proceedings Title
