 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.

Viscosity (mPa-s) for density 1 kg/l Density (kg/l) Examples of calculation N° 1. Changes in density (graph 2) Flow rate to be measured: 1000 l/h Liquid density: 1.4 kg/l Enter the graph at the 1000 l/h point and move horizontally to the left until the thick line that determines the proper flow tube (C33-10001). Follow the inclined line until crossing the 1.4 kg/l vertical line. From this point, move horizontally to the right until reaching the flow scale axis, where we can determine that the maximum flow rate we can measure with this tube is 800 l/h. N° 2.
