Details description
This product adopts a suspended screw-wing internal structure and a straight pipe section design. The impeller axis is in the same direction as the water supply pipe. It has the characteristics of wear resistance, small pressure loss, and small initial vibration. Built-in LoRa IoT chip, the LoRa IoT network is used to realize the remote reading function of water meter usage data.
The water meter has a built-in stainless steel ball valve, which can realize remote meter reading and remote control of the valve. For malicious users with arrears, the valve can be closed remotely. It is suitable for the management, measurement and charging of water meters with large water consumption such as corporate users, supporting master meters, and specific users. It is easy to maintain and easy to use. It is the preferred remote management water meter for large water users by the water resources management department and a large-diameter Internet of Things water meter.
Technical features
It has advanced technology and adopts a suspended propeller-type internal structure and a straight pipe section design. The axial direction of the impeller is the same as the axial direction of the water supply pipe. It has the characteristics of wear resistance, small pressure loss, small initial movement, and a longer service life than a rotor-type water meter;
The integrated design of the meter and valve, with built-in valve, can realize remote data transmission and remote control of the valve, and you can choose prepayment or postpayment. Prepayment method, automatic valve closing in case of default, is the preferred measuring instrument for water resources management and charging departments;
Each specification has wireless remote transmission type, wired remote transmission type, and card-type prepaid type to choose from;
Wireless remote transmission type, frequency range 470MHz~510MHz, wireless self-organizing network communication method, each water meter can act as a router, supporting up to 7 levels of routing. The battery voltage can be checked in real time through the management software for easy replacement;
Wired remote transmission type, M-BUS/RS485 bus communication method, low power consumption design, the normal working state is powered by the communication line, the built-in lithium battery can ensure normal measurement of the water meter for more than six years when the communication line is broken;
High precision, wide range, high-definition LCD display of usage data, dual electromechanical display
The installation methods are diverse, with horizontal or vertical installation options available, and the measurement accuracy is level 2.
Low cost, DN32\40\50, water meter size is the same, as long as different specifications of pipe joints and connecting threads are configured, different pipe diameters can be connected
Superior moisture-proof performance, passed the IP68 waterproof level test, you can use it with confidence
