    Remote read meters

    1- Low-power design, built-in 3.6V lithium battery service life ≥6 years

    2- With high and low temperature automatic compensation function; with forward and reverse high-precision measurement capabilities.

    3- Large LCD screen displays: forward and reverse flow, flow direction, flow rate, cumulative flow, instantaneous flow, unit, leak detection, empty pipe detection, low battery alarm, external power supply display, etc.

    4- It adopts Europe's mature NFC near-field communication technology, has an embedded NFC near-field communication circuit board, connects to the remote data monitoring terminal, and realizes NB-loT data communication; it can be equipped with a new NDC electronic module to realize pulse output, M-Bus, and LoRa remote transmission.

    5- Optional remote controlled meters.

    * NB-IOT

    * LORA

    * M- BUS

    - Frequency band: 800MHz～900 MHz.

     

    - Low-power design, built-in 3.6V lithium battery service life ≥6 years

     

    - Meter data be received and sent to the operator's cloud by the wireless transmission module through the NB-IOT channel.  

     

    The management software on server remote monitors the meters and settles the water bill based on the data extracted from the operator's cloud.

    - Frequency band: 470MHz～510 MHz

     

    - Low-power design, built-in 3.6V lithium battery service life ≥6 years

     

    - The concentrator communicates with the meters through Lora to receive data from meter, and sends data back to server by 4G/ Internet.

     

    - Water meter parameters can be set and modified by the hand holder by operator.

    - Communication Rate: 1200bps/2400bps/4800bps

     

    - The concentrator communicates with the meters to receive data from meter, and sends data back to server by 4G/ Internet.

     

    - The working voltage: DC24V powered by the bus; Built-in backup power DC3.6V, static current < 25μA.

    Mechanical characteristics & Parameters

    - The water meter can be easily upgraded to a remote water meter by replacing the cover with remote transmission module.
