Metrolog memory gauges are powered by lithium cell based batteries, operating at low and high temperature, specially designed by Metrolog called Smart batteries.

Thanks to the very low gauge consumption, their life has been widely extended and thus, can be used for extra long duration jobs.

Our batteries are Smart, as they know their remaining power any time.

During acquisition, batteries record the energy used by the gauge, taking into account the surrounding temperature, the current programming and the gauge actual consumption. The battery gets its remaining energy by subtraction.

The parameters needed for the calculations and the required statistics are permanently stored in the battery, so a battery can be switched from one gauge to another without loss of information: wen a gauge is connected to a computer, battery type and remaining energy are displayed for user's information.

The indication has an accuracy of ± 5 %. For jobs that cannot be easily repeated, no risk should be taken when the remaining energy is displayed to be a few days since there is no guarantee about the accuracy at that stage.
