What are the different classification standards for common household and industrial water meters? Household and industrial water meters are mainly classified according to measurement principles, usage scenarios, installation methods, measurement accuracy, and other standards. 1. According to the measurement principle, mechanical water meters measure water volume by rotating the impeller, including rotor dust difference or type (small flow rate) and spiral wing type (large flow rate), with low cost but average accuracy. Electronic water meter: using ultrasonic or electromagnetic induction principles, with no mechanical wear, high accuracy, and support for remote reading, suitable for intelligent water management systems. two According to the usage scenario, it is usually DN15-DN25 caliber, mainly mechanical, such as the common rotor type cold water meter. Industrial use: The caliber can reach DN300 or above, requiring high pressure resistance and high flow rate, such as compound water meters or electromagnetic flow meters. three Horizontal installation according to installation method: Most household meters require horizontal pipeline installation. Vertical installation: A specially designed vertical water meter suitable for space limited scenarios. four According to the measurement accuracy of Class A/B, it is mostly Class B for household use (with an error of ± 2%), and Class A for industrial use (with an error of ± 1%) is more accurate. R160/R400: Industrial meters have a higher measurement ratio (maximum/minimum flow ratio) and are adaptable to flow fluctuations. Other categories include hot and cold water meters (distinguished by blue/red markings), prepaid water meters (controlled by IC cards), and wireless Paiw
