8.10 Battery lifetime
The maximum battery lifetime depends on the choice of battery pack, the diameter and on the
measurement interval. Other factors influencing the battery lifetime include the ambient
temperature, the pulse output settings, the status output, the pulse width and the
Modbus baud rate settings . 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 and Modbus settings, an ambient
temperature of 25
°
C / 77
°
F and a flow rate at 2 m/s. The effect of the optional pressure and
temperature sensor decreases the battery lifetime with 5% (on average).
