Series AD Working principle A spring M keeps a disk B in zero flow rate position. When the fluid flows through the disk at a specific speed, a force is made on the disk B, moving it to an equilibrium position. The distance covered by B depends on: - The force of the fluid flow F. - The relationship between areas A & B. - The force in opposition of the spring C. The equilibrium between forces F and the one generated by C defines the position of the disk B, equivalent to flow rate. The disk B, which contains a magnet M, acts over the switches and/or the local indicator.
