The invention relates to measuring devices or display devices and a method for operating these devices, in particular instruments for level measurement, for level detection, for detecting the topology of a product surface or for displaying the measured values of these instruments. A measuring device or display device has an RFID unit. The RFID unit is set up to exchange data with a memory on an external command from an external communication device, to switch a controllable switch on and off, and/or to transfer energy to an energy storage device.

Described is a process measurement device having an interface for connecting a plug-in memory, in which a processing measurement device includes a memory operating device that can switch the process measurement device into a memory access mode when the memory is connected to the process measurement device. Also described is a power supply that ensures that the energy demand required for read access or write access to the process measurement device is automatically covered after the connection of the memory by increasing the amount of electrical energy that is freely available in the process measurement device. Undesired undersupply of the process measurement device can thereby be effectively avoided.

A radar level indicator comprising a processor, an analogue-digital converter circuit and an intermediate memory connected therebetween. The intermediate memory is configured to receive digital signals from the analogue-digital converter circuit at a first data rate. The processor is configured to read out the intermediate memory at a second data rate that is different from the first data rate.

The invention relates to a flow measuring instrument which ascertains the water level of a watercourse, the flow rate of the watercourse at a specific location, and the wind velocity at the location of the measuring instrument, and these three measurement data are incorporated in the calculation of the average flow rate of the watercourse and/or of the calculation of the flow. By taking the wind velocity above the watercourse into consideration, calculation of the flow can be improved.

Measuring a fill level or limit state is performed using an electromagnetic vibrating system, in which a transmission signal(s) is generated. A vibrating body () is excited into a state of vibration by the transmission signal (s); and by means of the reception signal (e) that is then produced by the vibrating body () the transmission signal (s) is modified for at least one subsequent excitation of the vibrating body (), while a natural frequency (fe) of the vibrating body&#x2014;or a magnitude (te) dependent on the natural frequency (fe)&#x2014;is determined from the reception signal (e), and the transmission signal (s) is thereby modified.
