    摘要： A water utility meter configured for dynamic throttling and arranged to register and manage the amount of water delivered to a consumption site from a distribution network is disclosed. The water utility meter comprises a flow sensor for measuring a flow rate through the water utility meter, a valve for limiting the flow rate from the distribution network to the consumption site, an actuator for changing a valve position so that the valve may be in an open position or a closed position or a variable throttling position and a controller unit arranged to control the actuator. The controller unit is further configured to monitor the flow rate using the flow sensor, to verify if the flow rate exceeds a maximum flow rate limit or does not exceed a minimum flow rate limit and if the limits are exceeded adjust the valve position to change the maximum flowrate.

    摘要： A modular ultrasonic flow meter including a substantially watertight meter housing connected; a measurement printed circuit board including a measurement circuit communicating with one or more ultrasonic transducers, arranged in the meter housing for transmitting and receiving ultrasonic signals; and a self-contained power supply. The ultrasonic flow meter further includes a control module comprising a module housing connected with a main printed circuit board including a central processing unit, a memory circuit and a communication circuit, and a power- and communication connection is provided between the main printed circuit board of the control module and the measurement printed circuit board whereby the self-contained power supply may power the main printed circuit board and the measurement printed circuit board.

    摘要： The present disclosure provides a method for separately detecting the amount of utility consumption by respective devices, the method including: acquiring first flow rate data corresponding to the supply amount of first-type water, which is supplied through a first supply pipe, in each meter-reading interval; acquiring electric power amount data corresponding to the supply amount of electric power, which is supplied through an electric power lead-in wire, in each meter-reading interval; and, via analysis of the first flow rate data and the electric power amount data, extracting the amount of consumption of the first-type water and the amount of consumption of the electric power by the first device in a time interval in which the use pattern of the first-type water by the first device and the use pattern of the electric power by the first device are concurrently detected.

    摘要： The invention relates to a method for detecting domestic hot water use by a sanitary fitting (200) during an observation period by analysing data relative to volumes of water passing through a water meter (400), the method comprising: receiving a first item of data, noted VΔ1, representing the maximum volume of fluid measured over a predetermined period, preferably equal to 5 minutes; receiving a second item of data, noted VΔ2, representing the maximum volume of fluid measured by the meter during another predetermined period, preferably equal to 15 minutes; and detecting that domestic hot water has been used when VΔ1 > 15 litres and VΔ2 ≥ 20 litres.
