The analysis of 0, 50, 100 mL/h of ultrafiltration net using a total volume of affluent (dose) of 900, 900 and 500 mL/h, respectively, during 120 min. A Shows the predicted cumulative UF, the weight measured cumulative UF, and the beaker measured cumulative UF. B Shows the Bland–Altman diagram measuring the agreement of UFnet measured through the affluent and effluent weight difference and UFnet predicted. C Shows the Bland–Altman diagram measuring the agreement of UFnet measured through the beaker and through the affluent and effluent weight difference. UF denotes ultrafiltration rate. The affluent and effluent pumps worked intermittently, synchronized, and with variable bits output from microcontroller. Predicted cumulative UFnet was calculated dividing the set UFnet/60 min and adding this value each minute observed during the experiment. The configuration 2 of Additional file 1: Fig. S4 was used in this experiment
