Totalizer / pulse output
The base units for the totalizer and the pulse output are m3 for volume,
m3 norm. for standard volume and kg for mass.
The unit and the conversion factor can be changed in menu item 3.2.8 "Tot.Conf.". User defined units (User Def.) can be selected and entered. The conversion factor of the unit must always be entered based on the base unit.
The maximum pulse output frequency is 0.5 Hz. To ensure that the pulse output does not exceed
0.5Hz, the conversion factor of the totalizer must be selected and set accordingly. The pulse output represents an exact copy of the whole number value of the internal totalizer.
Max. pulses per hour
fmax. ≤ 0.5 Hz

Max. pulses / hour = 1800 pulses
Example
Flow Qmax. | Factor A1 Coef. | Pulses / litre | Pulses / h | Comment |

5.6 m3/h | 0.001 | 1 pulse / 1 litre | 5600 | not possible |
| 0.01 | 1 pulse / 10 litres | 560 | 560 < 1800 = ok. |
