Abstract: An electromagnetic valve has a magnetic coil and a movable element coupled to a valve element. The magnetic coil, when excited, conveys the movable element in one direction to move the valve element from its initial position into its active position. A control circuit for the electromagnetic valve has a current source for optionally supplying current to the magnetic coil and a measuring device for measuring a voltage level of the magnetic coil and/or a current level through the magnetic coil. A monitoring unit which is connected to the measuring device establishes a switching state of the electromagnetic valve corresponding to the position of its valve element based on the intended current supply state of the current source and the current and/or voltage characteristic measured by the measuring device and, if appropriate, determines a fault state of the current supply and/or the electromagnetic valve.

Abstract: Communication between a terminal, such as a consumption meter, installed at a fixed location and a mobile data collector, by way of Wireless M-Bus, via a short-range radio receiver. Data from the terminal is forwarded to the data collector via a bidirectional WPAN interface. The terminal sends a message periodically and unprompted for the communication set-up and subsequently opens a reception window after a period of time. In response, a command or a command sequence is conveyed from the mobile data collector to the receiver and to the terminal in one or more reception windows. The receiver determines the reception time at which the message arrives at the receiver, and the receiver stipulates the time at which the command or command sequence is transmitted onward to the terminal, so that the command or command sequence is received by the terminal within one reception window or multiple reception windows.

Abstract: A method operates a measuring device used to determine a fluid variable. The measuring devices contains a vibration transducer driven to excite a wave in the fluid due to a test excitation signal. The wave is guided along a propagation path back to the vibration transducer or to an additional vibration transducer, thereby exciting the (additional) vibration transducer to vibrate. An output signal relating to this vibration is acquired, and a frequency of that segment of the output signal that lies in an analysis interval is determined. The analysis interval starts once the driving of the vibration transducer to excite the wave has finished, and/or once a maximum of the amplitude of the vibration is reached. The determination of the fluid variable is performed based on the determined frequency. An error message or a notification is output to a user and/or to a device external to the measuring device.
