Large Diameter Pulse Remote water meter

Large Diameter Pulse Remote water meter 
Overview
  Pulse water meter combines the advantages of passive direct reading and active pulse, and has greatly improved in terms of micro power, accuracy, waterproofness, and low cost. Only power on at the moment of counting, and all electronic parts are outside the water meter, which facilitates the replacement of sensors and base meters.

characteristic
 
1. The signal transmission part adopts self-holding switch technology to ensure the accuracy of signal transmission.
2. The base meter and sensor part adopt a split and detachable structure, which is convenient for maintenance.
3. The smart chip has a data storage function, which will not affect the normal recording of data when the data line or bus is disconnected and the system is powered off.
4. According to the needs of users, the design reading is accurate to 0.001m³, 0.01m³, 0.1m³, 1m³, 10m³ water.
5. The whole remote water meter is sealed and waterproof and can be used in humid environments.
     6. With anti-magnetic and magnetic interference self-decomposing functions.

Photoelectric direct reading water meter

    Photoelectric direct reading water meter has specifications of rotor-type measurement structure, high precision measurement,  small initial flow, easy meter reading, good looks, safety and health, long life and other characteristics.

    Photoelectric direct reading water meter uses a photoelectric direct reading technology to read the word wheel data, compared with the traditional pulse table, it can read the error reduced to zero, it is zero error electronic remote meter of automatic meter reading system in the electromechanical conversion, and use of low-power design, usually no power supply, only when it needs to power in the meter reading or valve it.

    Direct reading water meter with intelligent meter reading system equipment to complete the intelligent copy of the district of water, electricity, gas meter data, and to achieve with the settlement center network data sharing.
Features:
1. Meet the "electronic remote meter" (CJ / T224-2012) standards;
2. Usually no power, powers by the bus power supply only when meter reading / switching valve, data acquisition, data transmission or valve control according to the requirements of the command;
3. The meter has a unique address identifier, according to the address can read the corresponding data to ensure data uniqueness, correctness;
4. Control function, comes with the valve, according to the need to switch to prevent malicious arrears of water charge;
5. Combine with the host computer system, established remote automatic meter reading management system, really realized meter reading, monitoring automation.
