Primary elements for raising magnitudes e.g. volumetric flow, density, mass flow, viscosity and Reynolds number, has straight stretch section of cross-sectional pipe which is equal to conduit

摘要

The primary elements has a straight stretch section of cross-sectional pipe, which is equal to the conduit. The conduit contains a row tube, a fluid resistance based on a beam of capillary tubes and three intakes of pressure. The dense meter is connected to two intakes of fluid water located upstream and downstream of the fluid resistance. The density is determined by the extent of the burden equivalent to the correct weight of spare float filled with fluid for measuring.
