61 calculates the current water flow of quick volume pulses without average determination as the
number of volume pulses per 10 sec. multiplied by the scaling factor.
Q = (Imp./10 s. x flow factor)/65535

/h with 100 imp./l (CCC=419), flow factor = 235926
Current water flow = 317 l/h, corresponding to 88 Imp./10 s.
q = (88 x 235926)/65535 = 316.8 which is displayed as 316
