A rotameter can be included between the constant head tank and the flow control orifice in the dose controller to verify the flow rate of chemical. The motivation for this experiment was to determine whether the use of a rotameter would be feasible in the chemical dose controlling system. The head loss through the rotameter would need to follow the relationship of head loss proportional to the square of the flow rate. The head loss through the rotameter was measured to determine if it is suitable for use in the dose controller.

The head loss through the rotameter was be determined using the setup that is diagrammed in Figure 1. A peristalic pump was used to circulate the fluid at a certain flow rate. Two attenuators were used to minimize the effect of the pulsing from the peristalic pump, and one pressure sensor was used to measure the pressure difference before and after the rotameter.
