Abstract
Smart water meters play a crucial role in promoting sustainable urban development, optimizing water management, utility efficiency, and reducing environmental impact. Limited knowledge exists regarding their long-term performance across diverse conditions. This study assessed modern ultrasonic water meters in households, testing six pairs from five brands. Evaluations involved varying water flow rates, simulating starts and stops, abrupt supply changes, and durability assessments. Generally, the meters performed accurately, avoiding consistent over- or undercounting. However, performance varied across brands and models due to technological disparities. Integrated battery-equipped meters met accuracy standards, yet exhibited discrepancies in more demanding testing conditions.
期刊介绍：
Flow Measurement and Instrumentation is dedicated to disseminating the latest research results on all aspects of flow measurement, in both closed conduits and open channels. The design of flow measurement systems involves a wide variety of multidisciplinary activities including modelling the flow sensor, the fluid flow and the sensor/fluid interactions through the use of computation techniques; the development of advanced transducer systems and their associated signal processing and the laboratory and field assessment of the overall system under ideal and disturbed conditions.
FMI is the essential forum for critical information exchange, and contributions are particularly encouraged in the following areas of interest:
Modelling: the application of mathematical and computational modelling to the interaction of fluid dynamics with flowmeters, including flowmeter behaviour, improved flowmeter design and installation problems. Application of CAD/CAE techniques to flowmeter modelling are eligible.
Design and development: the detailed design of the flowmeter head and/or signal processing aspects of novel flowmeters. Emphasis is given to papers identifying new sensor configurations, multisensor flow measurement systems, non-intrusive flow metering techniques and the application of microelectronic techniques in smart or intelligent systems.
Calibration techniques: including descriptions of new or existing calibration facilities and techniques, calibration data from different flowmeter types, and calibration intercomparison data from different laboratories.
Installation effect data: dealing with the effects of non-ideal flow conditions on flowmeters. Papers combining a theoretical understanding of flowmeter behaviour with experimental work are particularly welcome.
