Chapter 3 Meter Specifications (by Type) 3.2 Vertical Axial Flow Impeller Type (Vertical Wortman) <Dry Structure, Screw-in Connection Type> (1) The vertical axial flow impeller type is a method of indirectly measuring the flow rate from the speed of the flowing water. The water flow inside the meter flows from bottom to top parallel to the rotating axis, rotating a vertically attached spiral impeller, and the principle is that the number of revolutions is proportional to the flow rate. The rotation of this impeller is transmitted to the totalization indication mechanism to mechanically convert the flow rate and display the total.
