What are the features of a pressure-free intelligent mixing valve?
What are the features of a pressure-free intelligent mixing valve?
Traditional bathhouses and shower rooms in bath centers all use dual-pipe water supply systems, with manual temperature-control valves used to adjust the water temperature to a comfortable level. When we’re taking a bath, we often find that the water temperature suddenly becomes too cold or too hot midway through, making it unsuitable for bathing. In such cases, we have to readjust the water temperature again.
A review of the correct usage and maintenance of water meters.
A review of the correct usage and maintenance of water meters.
When purchasing a water meter, you should first check whether the product has a manufacturing license for measuring instruments. For newly installed water meters, you should also verify that they bear the mark indicating they have passed the initial verification. Next, you need to inspect the meter carefully to ensure it does not compromise installation or operational safety. If necessary, you can entrust the relevant authorities, such as the Quality Supervision Department, to confirm whether the meter meets safety standards and to check for any instances of substandard workmanship, material substitution, or non-compliance with safety regulations.
Smart water meters are the primary method for measuring water consumption in daily life.
Smart water meters are the primary method for measuring water consumption in daily life.
Smart water meters are a popular type of water meter and are also the primary model promoted by water utilities. Smart water meters feature electronic displays that show water consumption data, including usage volume and associated costs—all clearly presented on an electronic screen. Unlike mechanical water meters, which often produce blurry or unclear readings that make it difficult to read accurately, smart water meters offer much greater clarity and ease of reading. As technology and the times continue to evolve, intelligent water meters will undoubtedly become the direction of future applications.
Fighting the epidemic—We’re taking action!
Fighting the epidemic—We’re taking action!
Recently, the Delta variant of COVID-19 has made a comeback. This mutant strain is more contagious and carries a higher viral load than previous strains. Outbreaks have been reported in cities such as Nanjing, Yangzhou, and Zhangjiajie. In the face of this war without smoke, businesses should even more closely align themselves with the Chinese people, share their fate, and work together to achieve victory in this battle.
Overcoming technical challenges, heat meters achieve a new breakthrough.
Overcoming technical challenges, heat meters achieve a new breakthrough.
The prices of domestic heat meters have consistently been lower than those of foreign heat meters, and the primary reason for this is that domestic manufacturers have yet to overcome the challenge of ensuring accurate measurement across the entire range of flow rates—a critical technological shortcoming. For an ultrasonic heat meter to be classified as a Class 2 meter, it must maintain a measurement accuracy of Class 2 under any temperature or flow rate within its specified operating range. However, current domestic brands can only be considered “quasi-Class 2” meters—meaning they achieve Class 2 accuracy only within a narrow temperature range. Once the temperature variation exceeds this narrow range, their accuracy will significantly degrade. Domestic brands have now broken through technical bottlenecks in another key area, reaching new heights. We will continue to strive relentlessly to accomplish more tasks and solve even more challenging problems.
How can we prevent smart water meters from being hacked and water stolen?
How can we prevent smart water meters from being hacked and water stolen?
Mechanical water meters are gradually being replaced by smart water meters, which have solved the problem of meter readers visiting households to take manual readings. This has also made it more convenient for users to check their usage and pay their bills. However, some users have begun to think about finding ways to hack and steal water. Many users, when installing smart water meters, secretly remove them and then connect the two pipes directly, bypassing the meter altogether. Until an effective regulatory mechanism is put in place, the only recourse is to rely on individuals’ moral integrity and property management practices. According to Article 49 of the Law on Public Security Administration Punishments, anyone who steals, defrauds, loots, snatches, extorts, or intentionally damages public or private property shall be detained for between 5 and 10 days and may also be fined up to 500 yuan. For more serious cases, the detention period will be between 10 and 15 days, and a fine of up to 1,000 yuan may also be imposed. If a user steals large quantities of water, it constitutes the crime of theft, and not only will they face a monetary fine but also administrative penalties. Smart water meter manufacturers have also taken certain measures. Each time a meter is removed, its technical features will trigger an alert, making it immediately obvious during inspections and helping to curb the phenomenon of smart meters being hacked and stolen.
