Product catalog summary
Overview: The document provides technical specifications and features of G2 Misuratori's smart meters, specifically models DN 15-25-32-40 and DN 20 and DN 50. These meters are designed for direct reading and data transmission via radio frequency at 868 MHz, supporting various protocols such as LoRaWAN and W-Mbus OMS.
Specifications:
  • Smart meters are equipped with radio modules for data transmission, supporting both fixed network and Walk-by/Drive-by protocols.
  • Models include single jet counters with protected rollers and dry dials, mechanical transmission, and are MID-approved for use with drinking water.
  • Data transmitted includes sensor ID, consumption data, hardware status, alarms, and battery level, with multi-level cryptographic security.
  • Configuration data can be modified remotely or via radio terminal.
  • Modules are resin-coated for outdoor use and CE certified.
Technical Data:
  • Flow rates and dimensions are specified for different DN sizes, with permanent flow rates ranging from 2.5 to 25 m³/h and overload flow rates from 3.125 to 31.25 m³/h.
  • Accuracy class is 2, with environmental class C (-25°C to +55°C) and pressure loss class ΔP at 0.63 bar.
  • Maximum permissible operating pressure is 16 bar, extendable to 25 bar on request.
Radio Module Specifications:
  • Wireless M-Bus and LoRaWAN protocols are detailed, with transmission frequencies at 868 MHz.
  • Data transmission includes sensor ID, consumption data, hardware status, and alarms, with configuration changes possible via remote or radio terminal.
  • Transmission distance for Walk-by/Drive-by is up to 500 meters under optimal conditions.
Additional Information:
  • Battery life is estimated at 10 years, with environmental operating conditions between -10°C and +55°C.
  • Smart meters are IP68 rated for protection and certified under the European Electromagnetic Compatibility Directive.
