Large Caliber Water Meter

一、Product Summary Dear users, thank you for using our large-caliber water meter. Please read this instruction manual carefully before using it, so that you can easily use our products. Large-diameter water meter is a measuring instrument used to measure the total volume of water flowing through tap water pipes, which is suitable for small-scale industrial water and residential water. Dry structure, vacuum sealing of counting mechanism, no influence of water quality on the wheel of dial, and permanent clear reading. The word wheel display counter value has large measuring range and high precision. The metering and other performance requirements meet GB/T 778.1 ~ 3-2007 Class B standard, and the electronic device meets the "Electronic Remote Transmission Water Meter" (CJ/T 224-2006) standard. 二、Working Principle Compared with the traditional pulse water meter, the large-diameter water meter can reduce the metering error to almost zero, which is an ideal metering zero-error water meter in the automatic meter reading system. Moreover, it adopts a low power consumption design, so it is not necessary to supply power normally, and it is only necessary to power up the water meter when it reads. 三、Function List Serial Number Functions Comments 1 Metering function Accumulated flow of real-time Hall counter 2 Water metering data history storage local 1.

Mechanical measurement and other performance requirements meet GB/T778.1 ~ 3-2007; The electronic device meets the standard of Electronic Remote Transmission Water Meter (CJ/T224-2012); 2. Compared with the traditional pulse water meter, it can reduce the reading error to almost zero due to the direct reading of word wheel data. 3. Low power consumption design is adopted, and power supply is required only when reading. 4. Advanced data coding and verification methods are adopted, with high communication reliability. 5. Meet the design requirements of EMC, ESD, EMI and other electronic products in terms of electromagnetic compatibility, reaching the industry leading level. 6. Combining with the upper computer system, a remote automatic meter reading management system is established to truly realize meter reading automation. 五、Technical Parameters   Model Overload flow Q4 Common flow Q3 Boundary flow Q2 Minimum flow Q1 Minimum reading Maximum reading M3/h M3 ZYLXL-50Z/R 31.25 25 3.15 0.5 0.01 999999 ZYLXL-65Z/R 50 40 5.04 0.8 0.01 999999 ZYLXL-80Z/R 78.75 63 7.94 1.26 0.01 999999 ZYLXL-100Z/R 125 100 12.6 2 0.01 999999 ZYLXL-150Z/R 312.5 250 31.5 5 0.1 999999 ZYLXL-200Z/R 500 400 50.4 8 0.1 999999 ZYLXL-250Z/R 787.5 630 79.4 12.6 0.1 999999 ZYLXL-300Z/R 1250 1000 126 20 0.1 999999 六、Product structure and size The outline of the water meter is shown below,    See the following table for water meter dimensions.
