Jiangbei NB Woltman - Model LXLCY-50W to LXLCY-500W -Wireless Remote Reading Water Meter

NB Woltman Wireless Remote Reading Water Meter Dry Type LX LCY - 50 W to LXLCY-500W ( 50 mm to 500 mm) is a wireless remote reading NB woltman water meter of low power consumption based on the wireless communication technology of narrowband cellular, with split design (the electronic parts.

• The mechanical part of NB meter is woltman dry type, with the high accuracy, low starting flow rate, easy reading, long lifetime, etc.
• The meter body is iron.
• Meeting EMC/ESD/EMI, the design requirements of electromagnetic compatibility for the electronic products, reaching the industrial leading level.
• The wireless module is separated with the mechanical part, for easy maintainance.
• The electronic parts are separately sealed, and the water proof grade can be IP 68.
• Adopting the advanced technology of data coding and verification, with high communication reliability.
• NB water meter is communicating directly with NB-IOT base station, without collector and concentrator as the reading system.
• Combined by the host computer, building a remote reading management system, to ensure an automatic reading and monitoring.
• Water meter data cycle reporting: it can be set up accordingly to report the data hourly, daily, monthly, including the accumulated water volume, battery capacity, meter status as well as the reporting period.
• Convenient mechanical reading: the reading would not be affected after assembling the NB wireless module.
• Stable signal: with the NB-IOT base station, NB meters set up a network by the core network to make sure a stability of the signal.
• No wiring, and easy installation.
• Advantage of the Narrowband Cellular Technology of NB-IOT.
• Pulse: 100 L/Pulse or 1000 L/Pulse (optional)
• Low power consumption
• Deep coverage of 20 dB and gain (more penetration of a wall than 2G).
• Low cost, multilink (meter reports data directly to base station, without the help of the intermediate equipment.
• Security (adopting cloud management platform to ensure the safety of the clients)
• Reliability of internet (adopting the specific internet to ensure constant and stable operation.
• Reusing the current cellular internet (fast and cheap).
• Global standard cost and roaming.
• Electromechanical conversion error: ΔV≤±1 signal equivalent.
