A fast flow-diverter for use in a laboratory in primary flowmeter calibration
Abstract
A description is given of the hydraulic system recently installed at the Istituto di Metrologia G. Colonnetti (IMGC) in the Section for Mass and Volume Measurement to calibrate flowmeters in the range of small and medium flowrates, which can be extended up to 1 cu m/sec. This article describes in detail the mechanical device for diverting the flow in the weightank. The device was developed according to an original principle of construction, in order to obtain very short operation times (about 10 ms), and to obtain an accuracy of time measurement comparable to the accuracy of mass measurement.
