A measurement device arrangement includes a measurement device measuring a distance to an object, for example in the form of a depth measurement. A control unit is provided, which calculates the point in time for the next distance measurement, taking account of current or predicted weather conditions at the location of the measurement device. The frequency of the measurement can thus be adjusted to the weather conditions in order to reduce the power consumption of the measurement device without having to go without punctual reports of depth changes in the process.
