Henan Fire Protection Water Meter The lack of effective supervision over the quality of water meters is a significant issue. In Europe and the United States, the regulation of products that come into direct contact with ordinary citizens has reached a level that is almost harsh or even severe. For example, in 1998, the European import of poultry products from China led to losses of billions of dollars due to stringent residue standards for poultry products. Chinese experts expressed great indignation over this, as China's poultry exports primarily go to Central Europe and some Western European countries. The increase in residue standards can only increase safety probabilities by one in a billion, which is far less than the total population of Europe fifteen years later. In China, however, there is a lack of effective regulation on issues related to people's livelihoods. For instance, in Fushun City's Wanghua District in 1988, over eight hundred children were vaccinated with a polio vaccine, resulting in more than one hundred cases of varying degrees of adverse reactions, with over sixty children left with lifelong disabilities. Yet, as of 25 years later, none of the main responsible persons faced any consequences. To this day, there is still no conclusion on how the vaccine was contaminated. With such regulation, substandard water meters naturally find a breeding ground.
Convenient to use, reliable performance, affordable price1. One meter per household, non-duplicable, pre-collected fees, no need for meter reading, is a technological means for the water supply department to achieve scientific and intelligent management.
2. Utilizing ultra-large-scale dedicated microprocessor integrated circuits, high-reliability design, and specialized manufacturing methods, it possesses superior features such as moisture-proof, damp-proof, anti-interference, and anti-tampering.
3. Dual signal sources and interrupted pulse method for reading collection ensure interference-free transmission of effective signals, accurate and error-free.
4. Comprehensive preventive measures: dual collection signals, power batteries, input card slots, and the water meter itself are all protected and alerted against illegal strong magnetic interference, strong current impacts, disconnection, short circuits, disassembly, and power cuts.
5. Users purchase water cards equipped with high-capacity AT88SC1608 logic encryption cards and various encryption technologies, providing good anti-counterfeiting features. These can be combined or managed independently for eight types of meters, implementing bank electronic currency and one-card management.
