Battery life The battery has a maximum battery life of 15 years.
The battery life, and thereby the availability of the measuring device if powered by batteries, depends
on a number of factors, including:
• The number of batteries
• The ambient conditions
• The frequency of data transmission via the GSM/GPRS modem
• The size of the files transmitted
• The interface activities (use of local operation, GSM/GPRS modem etc.)
• The selected measured value acquisition method:
– "MAX. LIVE" (max. battery life): measured value acquired every 15 seconds.
– "SMART" (dynamic control of measurement data acquisition): measured value acquisition depends on the
flow profile. The measuring device records the measured value every 5 seconds. The frequency of the
measured value acquisition cycle is increased if the measuring device detects a change in the flow profile.
The measuring device is supplied with the "SMART" measuring mode as standard.
– "AVERAGE": measured value acquisition every 3 seconds.
– "CONTINUOUS": continuous measured value acquisition.
