Correlation and agreement of normal saline weight and beaker measured volume, using intermittent flow (approximately 4 s on and 4 s off). The pump number 2 was used. A Shows the correlation of the decay of weight and volume in balance 1 (affluent) with the volume transferred to the balance 2 (effluent). B Shows the correlation of normal saline weight gain in balance 2 (effluent) with the volume transferred from the balance 1 (effluent). C Shows Bland–Altman diagram agreement between normal saline weight decay in balance 1 (affluent) with the volume transferred to the balance 2 (effluent). D Shows Bland–Altman diagram agreement between normal saline weight gain in balance 2 (effluent) with the volume transferred from the balance 1 (affluent). The configuration 1 of Additional file 1: Fig. S4 was used in this experiment. Using 5 and 10 bits from microcontroller output. A total of 28 data points were collected. Pump 2 was arbitrarily chosen since both pumps had the same behavior during the experiment number 1
