A smaller starting flow rate, with a starting flow rate of less than 0.5L/H; the low flow can reach 0.1 L/H, which is more than 16 times that of ordinary water meters. 2. In the micro-flow state of 0.5L/H to 14L/H, it measures intermittently (similar to a volumetric water meter), and the measurement error in this micro-flow range is small. 3. In the flow range from 14L/H to large flow, the anti-drip mechanism is disengaged; in this flow range, this product is completely the same as ordinary water meters; its measurement value error and pressure loss are completely the same as ordinary water meters, meeting the national standards for cold water meters. 4. This product can pass particles and impurities below 4mm at the anti-drip mechanism without being blocked or jammed, ensuring the normal operation of the anti-drip mechanism and water meter for over 6 years. 5. This product has good anti-inertia performance; when users are not using water, the water meter will not rotate by itself, and its anti-reverse performance is the same as that of B-class turbine water meters of the same caliber. 6. The product and technology have been certified by experts convened by the Ministry of Construction and the China Water Association, reaching domestic standards. The Chifeng electronic card water meter is susceptible to five types of attacks: 1. Vibration: General users may use their hands or place a thick mat, causing the IC card water meter to fail to register or under-register, which is not visually detectable as a mechanical attack. 2. Static Electricity: Using an electronic lighter inserted into the IC card slot, the static electricity generated by the lighter attacks the electronic components of the water meter, causing electronic component damage to save water. 3. Magnetic Attack: Using a magnet to interfere with the sampling and transmission parts of the water meter, causing the IC card water meter not to register or under-register, thus achieving water theft. 4. Water Attack: Adding a small amount of water to the card slot, causing moisture, which increases the power consumption of the user's IC card water meter or damages it. 5. Freezing: The operating temperature of the IC card water meter should not be below -40 degrees Celsius; however, during transportation, it may be exposed to temperatures below zero. Therefore, this aspect should also be considered during the design process. Additionally, the user's IC card water meter should have an anti-disassembly device - heat shrink film. If disassembly occurs, the valve will close, preventing water use. This water meter, combined with the remote reading system, greatly improves reading efficiency, saves labor costs, and increases water fee recovery rates for water supply companies. It is a product used in the "one meter per household, metering outside the household" project renovation for water supply companies and real estate companies. The company's R&D department is continuously enhancing the development of new products to support various water supply enterprises!
