 6000-PVC wetted parts in PVC. Other components in Working principle The 6000 series flowmeters work according to variable area principle, which is obtained by a float that moves inside a borosilicate glass tapered tube. The fluid flows up through the tapered tube forcing the float to a position with sufficient free area to enable the flow to pass, where there is an equilibrium of forces: - E = force of the fluid flow galvanized and coated steel wetted parts in PP. Other components in galvanized and coated steel  6000-PTFE wetted parts in PTFE. Other components in galvanized and coated...

Flow rate equivalent curves water-liquids (with different density and viscosity) Flow rate Flow rate Change in viscosity (graph 1) Change in density (graph 2) Viscosity (mPa·s) for density 1 kg/l Nº 1. Changes in density (graph 2) If the point lies between two curves, it is optional to select: Required flow rate 1000 I/h, density 1.4 kg/I. Enter the graph at the 1000 I/h point. Move horizontally across to applicable flow tube line (C313-1000), travel the inclined line to the point of the density of the fluid (1.4 kg/I). Travel horizontally to the vertical axis and read the equivalent flow...
