A method of operating a diaphragm valve is specified. The diaphragm valve comprises a fluid housing having a valve seat formed therein, a diaphragm which cooperates with the valve seat to open or close a flow path through the fluid housing, and at least two sensors from the following group: a capacitive sensor, which is arranged such that the diaphragm is located at least in sections in the electric field of the capacitive sensor, a temperature sensor, a pressure sensor, a force sensor, a pH sensor, a stress sensor and a vibration sensor, wherein an index value is formed from the measured values of the different sensors by means of a data fusion algorithm at at least two points in time, wherein a degree of wear of the diaphragm is determined on the basis of a change in the index value. Furthermore, a diaphragm valve is specified.

Method of operating a diaphragm valve and diaphragm valve

A diaphragm valve having a movable diaphragm () configured as a closure element has a valve housing () and an actuator (), the diaphragm () being clamped between a flange () of the valve housing and a base () of the actuator () and being provided with a first identification means () in which data which are adapted to be read out wirelessly are stored. A further identification means () is also fastened to the flange () and/or the base (). The read-out surfaces of the further identification means () are substantially at right angles to the read-out surface of the identification means () on the diaphragm ().

A measuring device with a fluid module is proposed, which comprises a measuring tube through which a fluid can flow and at least one acoustic measuring unit. The at least one acoustic measuring unit comprises at least one transmitter, at least one receiver as well as at least one waveguide. The measuring tube has at least one measuring section with a substantially angular internal cross section and at least one connecting section with a non-angular internal cross section, wherein the measuring tube has at least one transition section, which extends between the measuring section and the connecting section. The transition section has an internal cross section identical to the internal cross section of the measuring section at an end allocated to the measuring section and further an internal cross section identical to the internal cross section of the connecting section at an end allocated to the connecting section. Furthermore, a fluidic system is described.
