Abstract
Battery-operated field devices and methods for operating battery-operated field devices, in particular field devices for fill level measurement, for determining a limit level, for detecting a topology of a filling material surface, or for displaying the measured values of these devices, is provided. A battery-operated field device, which may be a fill level sensor device, a flow sensor device, a pressure sensor device, or a display device, includes an energy storage means, a time management unit connected to the energy storage means via a first line, and a radio unit connected to the energy storage means via a switch, the radio unit being configured to transmit time information about a next measurement via a first interface to the time management unit and/or to receive the time information from the radio unit, when the switch is activated.
