A data acquisition system using LabVIEW software and the Arduino microcontroller for a test bench of centrifugal pumps connected in series and parallel has been developed. The acquisition system allows real-time display of centrifugal pump discharge pressure values, voltage, current and volumetric flow of the test bench. A description of the system operation (front panel and block diagram) as well as the elements (actuators, instruments, controller and software) used in the system is given. From the front panel it became possible to operate the test bench for three modes of operation (Individual, Series and Parallel). Pressure, voltage, current and volumetric flow values were recorded over time and stored in a text file generated by the acquisition system.
