Item Open Access Design of a large scale flow-meter test and calibration facility(FEDSM2000 FORUM ON FLUID MEASURENMENT AND INTRUMENTATION BOSTON, MASSACHUSETTS, ON JUNE 11-15, 2000, 2000-06-11) Corrales-Barallobre, C.; Martínez-Huen, R.; Alvarez, Luis; Polanco, G.; Rojas-Solorzano, L.The design and set up of a large-scale flowmeter calibration and test facility is presented. The facility was designed to handle flowmeters with diameters between 6” and 14”, flow rates up to 0.3 m3/s and to give results less than 1% accurate. The calibration methodology consisted firstly in calibrating the pattern flowmeters, using volume and time primary measurements, and secondly, comparing the pattern to the flowmeters needing calibration. The design and calculation of the primary calibration device is addressed, including numerical simulations of the outflow manifold and the comparison to experimental data. The calibration facility proved to be accurate and reliable in producing renewed calibration data for various tested flowmetersItem Open Access Design of the distribution manifold for a large-scale flowmeter calibration facility(FEDSM2000 FORUM ON FLUID MEASURENMENT AND INSTRUMENTATION BOSTON, MASSACHUSETTS, ON JUNE 11-15, 2000, 2000-06-11) Corrales-Barallobre, C.; Martínez-Huen, R.; Alvarez, Luis; Polanco, G.; Rojas-Solorzano, L.The design and test of the distribution manifold for a large-scale flowmeter calibration facility is presented. The design was intended to have an air-free flow operation and a free-surface flow-like towards the downstream half-body discharge. Back of the envelope calculations are presented for the estimation of the preliminary dimensions. Numerical simulations of the flow during manifold steady state operation are utilized to refine the manifold design. No air entrapment is noticed in the flow simulation
