... But very often a precise total flow over a longer period is of higher interest than a fast single measurements. For this purpose the ASF1430 can be set to slower read out times (see 0). The sensor internally still integrates slices and recognizes fast signal changes but for the read out the total flow over the whole period is calculated ...
