摘要

智能水表在促进城市可持续发展、优化水资源管理、提高公用事业效率和减少环境影响方面发挥着至关重要的作用。关于它们在不同条件下的长期表现的知识有限。这项研究评估了家庭中的现代超声波水表，测试了来自五个品牌的六对水表。评估包括改变水流速率、模拟启动和停止、突然供应变化和耐久性评估。一般来说，仪表表现准确，避免了一致的多计或少计。然而，由于技术差异，不同品牌和车型的性能各不相同。集成电池配备的仪表满足精度标准，但在更苛刻的测试条件下表现出差异。

Behavior of domestic ultrasonic water meters subjected to multiple tests

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.
