产品概述 Product Overview

光电直读水表采用了光电直读技术读取字轮数据，与传统脉冲表相比，它可将读数误差降低至零，是自动抄表系统中机电转换误差小的电子远传水表，且采用了低功耗设计，平常无需供电，仅在抄表或开关阀门时才需对它供电。光电直读水表配合物联网智能抄表云管控平台，完成用水数据抄读，并实现与结算中心连网数据共享。 用来测量流经自来水管道饮用水的总量并通过M-BUS总线或485 总线传输给二次仪表。

The photoelectric direct reading water meter adopts photoelectric direct reading technology to read the character wheel data. Compared with traditional pulse meters, it can reduce the reading error to zero. It is an electronic remote water meter with zero electromechanical conversion error in automatic meter reading systems, and adopts a low-power design. It usually does not require power supply and only needs to be powered when reading meters or opening and closing valves. The photoelectric direct reading water meter is combined with the IoT intelligent meter reading cloud control platform to complete water data reading and achieve data sharing with the settlement center. Used to measure the total amount of drinking water flowing through the tap water pipeline and transmit it to the secondary instrument through M-BUS bus or 485 bus.

产品特性 Product Features

1. 内置CPU、存贮芯片和通讯模块。只需在采集水表数据时供电。由光电管读出水表字轮编码，经CPU 判断产生数字并由M-BUS 总线 或485 总线输出。

2.LXLC50-300 为可拆螺翼式水表，计数器与下层结构分离，读数永久保持清晰，更换计数器可在不停水情况下进行，水表维修无需从管道上拆卸水表设备。

3. 符合《电子远传水表》(CJ/T224-2012) 标准；流量性能符合GB/T778.1-3-2007 标准，准确度等级：2 级。

4. 兼容多种通讯规约：MODBUS-RTU、DL/T645、CJ/T188 内部协议。

5. 信号传感器采用无源器件，无需电源即可输出开关信号。

6. 传感器装置采用不锈钢外壳外加屏蔽层，可有效防止磁场干扰，防止用户盗水现象的发生。

7. 传感器装置采用全密封结构，防水级别IP65，防水防潮。

8. 准确率100%：直接识别计数器当前数字、电子读数与基表数据吻合，真正达到零误差实时抄表。

9. 无累计误差：直接读取表计的窗口市值，不计脉冲数无累计误差。

1. Built in CPU, storage chip, and communication module. Just need to supply power when collecting water meter data. Read the water meter character wheel code from the photoelectric tube, generate a number through CPU judgment, and output it through M-BUS bus or 485 bus.

2. LXLC50-300 is a detachable spiral wing water meter, with a counter separated from the lower structure and a permanently clear reading. The counter can be replaced without stopping the water supply, and water meter maintenance does not require dismantling the water meter equipment from the pipeline.

3. Complies with the standard of "Electronic Remote Water Meter" (CJ/T224-2012); The traffic performance meets the GB/T778.1-3-2007 standard, with an accuracy level of 2.

4. Compatible with multiple communication protocols: MODBUS-RTU, DL/T645, CJ/T188 internal protocols.

5. The signal sensor uses passive components and can output switch signals without the need for a power supply.

6. The sensor device adopts a stainless steel shell with an external shielding layer, which can effectively prevent magnetic field interference and prevent users from stealing water.

7. The sensor device adopts a fully sealed structure, with a waterproof level of IP65, and is waterproof and moisture-proof.

8. 100% accuracy: Directly identify the current number of the counter, the electronic reading matches the base meter data completely, and truly achieve zero error real-time meter reading.

9. No cumulative error: Directly read the window market value of the meter, without counting the number of pulses, and there is no cumulative error.
