8.7 Battery lifetime
The maximum battery lifetime depends on the choice of battery pack, the diameter and the
measurement interval.
Other factors influencing the battery lifetime include the ambient temperature, the pulse output
settings, the status output, and the pulse width. The graphs show the battery lifetime for the
different available battery types and measurement intervals.
Conditions
The maximum battery lifetime is based on default menu settings, an ambient temperature of
25°C / 77°F and a flow rate at 2 m/s.
