    Abstract: A magneto-inductive flow measuring device for measuring the flow of a flowable medium is described. The flow measuring device includes a measuring tube, a pair of coils, which are arranged opposite one another on the measuring tube and which are designed to produce an alternating magnetic field, which can be turned on and off, and which extends essentially transversely to the longitudinal axis of the measuring tube, as well as a pair of permanent magnets, which are arranged opposite one another on the measuring tube and which are designed to produce a permanent magnetic field, which extends essentially transversely to the longitudinal axis of the measuring tube. Moreover, the flow measuring device includes one or more pairs of measuring electrodes arranged opposite one another on the measuring tube, of which one pair of measuring electrodes is designed, in the case of turned off alternating magnetic field, to tap a measurement voltage induced by the permanent magnetic field, and an evaluation unit, which is designed, in the case of turned off alternating magnetic field, to monitor the measurement voltage induced by the permanent magnetic field, at least in the case of a predefined change of the measurement voltage, to turn on the alternating magnetic field and, by means of the alternating magnetic field, to determine a measured value for the flow.

    Abstract: A circuit arrangement comprises a voltage regulator coupled to an external voltage supply and a control loop associated with the voltage regulator. The control loop includes an electrical current controller for setting the electrical current value, an analog-digital converter, a reference resistor and a computation/control unit coupled with the voltage regulator and the said analog-digital converter, and the control loop is so embodied that the voltage regulator, as a function of the presently set electrical current value, controls a voltage to an external load connected with the electrical current output. Particularly the computation/control unit is adapted to calculate a voltage to be delivered by the voltage regulator and to operate both, the electrical current controller and the voltage regulator for setting the electrical current value and to operate and for tuning the voltage delivered by the voltage regulator as a function of the presently set electrical current value, respectively.

    Abstract: A method for determining a quality of a wireless transmission of data packets of a field device via a wireless communications interface to a higher-level unit comprises sending the data packets via the wireless communications interface to the higher-level unit, wherein the data packets are sent intermittently; receiving the data packets through the higher-level unit; checking whether the time duration between two data packets received by means of the higher-level unit, a size of the respective data packets, and/or information stored in the respective data packets fulfills a criterion; and determining a communications status depending upon the check and optional output of the communications status.

    Abstract: An electronic device having a housing for accommodating electronic components, preferably electronic components forming a process transmitter. The housing has two chambers, in which electronic components and user interfaces and/or connection elements for cable are arranged. The electronic components are arranged in a first chamber. In the case of a process transmitter, which is simple to maintain, electronic components are arranged exclusively in the first chamber, while user interfaces of the electronic components and/or connection elements for cable are positioned exclusively in the second chamber.
