Abstract: A method for determining the volume fraction of a phase of a multiphase medium, wherein the medium has a first phase with a first value for a first electrical parameter and, at least temporarily, a second phase with a second value for the first electrical parameter. The medium is impinged with a plurality of electrical excitation signals via a pair of electrodes and a plurality of corresponding electrical response signals are captured for the electrical excitation signals. A plurality of values for the first electrical parameter of the medium is determined from the plurality of excitation signals and the plurality of response signals. The volume fraction of the second phase in the medium is determined by identifying a scattering value of a statistical scattering measure from the plurality of determined values and by using a mathematical relationship between the statistical scattering and a volume fraction of the second phase.

Abstract: A flowmeter includes a control and evaluation unit, a sensor unit for capturing a primary variable, and a memory for storing data sets. The control and evaluation unit has a computing unit for determining the flow rate and/or for operating the sensor unit. The sensor unit is connected to the computing unit. During operation, the computing unit determines the flow rate from the primary variable, and determines the flow rate based on a data set and/or controls the sensor unit based on a data set. The data set includes a set of calibration values and/or a parameter for the operation of the sensor unit, and/or a parameter for determining the flow rate. The data set is assigned to a value of a state variable. The state variable is a medium parameter and/or a process parameter. The computing unit exchanges the data set depending on a change in the state variable.

Abstract: A method for operating a field device for process measurement technology includes: capturing and storing fieldbus messages in a learning mode; in a plurality of capture steps, at least partially storing the captured and stored fieldbus messages as a learning data set in each case if a status rule of the field device is fulfilled, so that a plurality of learning data sets are captured; in an evaluation step, evaluating a plurality of learning data sets to derive a message rule dependent on at least one fieldbus message for changing from normal mode of the field device to diagnostic mode of the field device; and applying, by the field device, the message rule for changing from the normal mode of the field device to the diagnostic mode of the field device instead of or in addition to the status rule.

Abstract: A method for operating a filling system with first and second filling points is disclosed. The first filling point has a first unit for controlling and monitoring the filling of the first filling point. The second filling point has a second unit for controlling and monitoring the filling of the second filling point. The first and second units are connected via a communication channel. In an operating state, the first filling point switches to diagnostic mode. The first unit reports the diagnostic start to the second unit. The first unit outputs substitute flow rate or level values. The second unit transmits a deviation message to the first unit in the event of a deviation of the current flow or level value from an expected value. After receipt of the deviation message, the first unit interrupts diagnostic mode and switches to normal operation or outputs corrected substitute flow or level values.
