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.

A liquid quality management device capable of being added to a liquid supply system which can supply a liquid within a storage container to a dispensing device in order to cool the liquid, and can dispense the liquid to a drinking container. The liquid quality management device includes an actual flow rate preparation unit including a flow rate sensor for determining an actual measured flow rate of the liquid; a dispensing liquid temperature sensor for measuring a temperature of the liquid dispensed into the drinking container; and a determination unit electrically connected to the actual flow rate preparation unit and the dispensing liquid temperature sensor, for determining an integrated flow rate of the liquid when the liquid temperature is equal to or higher than a set temperature, and for determining whether or not coolability of the dispensing device is suitable by comparing the integrated flow rate with a determination value.

A configuration tool adapted to configure a quality control system to monitor and/or guide an operator in a working environment through recognition of objects, events or an operational process, comprises: a volumetric sensor adapted to capture volumetric image frames of the working environment while an object, event or operational process is demonstrated; a display, coupled to the volumetric sensor and configured to live display the volumetric image frames; and a processor configured to: generate a user interface in overlay of the volumetric image frames to enable a user to define a layout zone; and automatically generate a virtual box in the layout zone when an object, event or operational process is detected during demonstration of the object, event or operational process.

The present invention relates to a hand-held volume measuring device configured for being clamped onto part of a urinary catheter and for measuring the volume of urine miming through the urinary catheter over a period of time.

Techniques for the design and operation of an efficient battery-powered meter are described herein. A metrology unit of the meter may be at least partially located in the gas flow of a pipe, and measures gas flow rate data according to a static flow sensor. The metrology unit calculates raw gas-volume data using at least the flow rate data as input. The metrology unit measures gas temperature to produce gas temperature data, and adjusts the raw gas-volume data, based at least in part on the gas temperature data, to produce corrected gas-volume data. The metrology unit accumulates the corrected gas-volume data over multiple minutes, hours or even days, and then sends the accumulated corrected gas-volume data to an index unit of the meter. By accumulating the data over time, fewer data transmissions are required. The index unit may send the accumulated the accumulated corrected gas-volume data to a utility server.

A system is provided for tracking, in a distributed water infrastructure, water usage by category. The system may comprise at least one processor configured to receive from at least one sensor associated with the distributed water infrastructure signals indicative of water usage in the distributed water infrastructure. The system may, based on the signals indicative of water usage, construct a plurality of profiles. The system may assign each profile to one of a plurality of water usage categories.
