Photoelectric direct reading valve control direct drinking water meter

Photoelectric direct reading valve control direct drinking water meters are advanced water measurement devices that combine the precision of photoelectric reading technology with the convenience of valve control. Here is a detailed description of the product:

1. Photoelectric Direct Reading Technology: These meters utilize photoelectric sensors to directly read the spool data, reducing reading errors to zero compared to traditional pulse meters. This technology offers electronic remote water metering with zero electromechanical conversion error in the automatic meter reading system.

2. Low Power Consumption Design: The meters are designed with low power consumption, requiring power supply only during meter reading or valve switching, making them energy-efficient.

3. Advanced Data Encoding and Verification: They adopt advanced data encoding and verification technology, ensuring high communication reliability.

4. Rotor Metering Structure: Featuring a rotor type metering structure, these meters offer high metering accuracy, convenient meter reading, and an aesthetically pleasing appearance.

5. Compatibility with Multiple Communication Protocols: The meters are compatible with multiple communication protocols, including DL/T645, CJ/T188, and internal protocols, allowing for versatile integration with various systems.

6. EMC, ESD, and EMI Compliance: They meet the design requirements of EMC (Electromagnetic Compatibility), ESD (Electrostatic Discharge), and EMI (Electromagnetic Interference), reaching an industry-leading level.

7. Valve Control Capability: The meters can be integrated with a host computer system to establish a remote automatic meter reading management system, enabling automation of meter reading and monitoring. They also feature the ability to remotely control the opening and closing of individual meter valves.

8. Technical Parameters: The product model includes lxsxy-15/20, with a working voltage of DC 36V for the M-Bus interface and DC 12V for the RS485 interface. The working current for meter reading is ≤ 2.5mA, and the static working current is ≤ 1.3 mA. The valve on/off bus current is ≤ 16 mA.

9. Working Environment: The meters are designed to work in a water temperature range of 0.1℃ to +45℃ and a humidity of 0 to 95% RH. The storage temperature range is -25℃ to +65℃, and they can withstand a maximum water pressure of 1 MPa with a maximum pressure loss of 0.063 MPa.

10. Communication Mode and Protocol: The meters communicate with the host computer via M-BUS or RS485, with a communication transmission rate of 2400 baud and a maximum communication transmission distance of 300m.

11. Valve Type and Operation Time: The meters are equipped with motor valves, and the opening/closing time for a single meter valve is 15 seconds.

These photoelectric direct reading valve control direct drinking water meters offer a combination of advanced technology, precision, and convenience, making them ideal for modern water management systems.
