The New NIST Water Flow Calibration Facility



V S. Gowda, Tsyh Tyan Yeh, Pedro I. Espina, N Yende


A static-gravimetric liquid flow calibration facility is under construction at the NIST Gaithersburg Campus. The facility is designed to calibrate flow meters from 25 mm to 400 mm in diameter, at flow rates from 8 L/min to 38,000 L/min. It incorporates a diverter valve design, which minimizes the uncertainty associated with conventional diverter valve designs. This paper details design and construction novelties of the system and outlines the expected uncertainty budget for the calibration facility.
