Abstract: A method for fluid flow measurement for a discrete area of a fluid supply network, where the fluid supply network includes a network of pipes that includes a main pipe for transporting fluid from a source into the fluid supply network for delivery to consumers, wherein the main pipe crosses a boundary between the discrete area and a further area of the fluid supply network, which is outside of the discrete area, and a plurality of distribution pipes each transport fluid from the main pipe to a consumer, where fluid pressure and the fluid consumption on at least two selected key metering points located inside and outside of the discrete area are measured, and where the fluid pressure and the fluid consumption measured on these selected key metering points the fluid flow in the main pipe that crosses the boundary of the discrete area is calculated.

Abstract: An apparatus for monitoring of a device including a moveable part, especially a rotating device, wherein the apparatus includes a control module which receives a measured vibration signal of the device provided by a sensor connected to the device, provides a spectrum of the measured vibration signal, pre-processes the spectrum to determine base frequencies and side frequencies, where the base frequencies are frequencies having peak powers corresponding to eigen frequencies of the device or faulty frequencies and the side frequencies correspond to other frequencies, where the control module additionally processes the base and side frequencies by applying separately a one-class classification on the base and side frequencies, combines the results of the one-class classifications to obtain a classification signal representing a confidence level, and outputs a decision support signal based on the classification signal, where the decision support signal indicates an error status of the monitored device.

Abstract: An apparatus for monitoring of a pump includes a control module, and an error detection unit, wherein a support vector machine based module is provided that receives an estimated output quantity data value from the control module, processes the estimated output quantity data value to provide a processed estimated output quantity data value via the support vector machine, and supplies the processed estimated output quantity data value to the error detection unit instead of the estimated output quantity data value of the control module.
