Acquisition of the flow and pressure values and calculation of the head (tests performed conforming to the norms ISO5198 and ISO9906)

The system performs a test feeding the pump at the indicated voltage. The operator adjusts the valve in order to get as close as possible to the set flow value. Once the set flow rate value is reached, the system performs the electrical measurements, then reads, for the duration of the set time, the values ​​of: current, power, head and verifies that all results are within the acceptance tolerances, then it will measure the next prevalence flow point.
