WEF-HV Smart Meter

Product catalog summary
Overview: The document provides technical specifications and operational details for direct reading smart meters with data transmission capabilities via radio frequency at 868 MHz. It outlines various models and protocols used for data transmission, including LoRaWAN and W-Mbus OMS.
Specifications:
  • Smart meters are equipped with radio modules supporting LoRaWAN for fixed networks and LoRa for Walk-by/Drive-by operations.
  • Models include WEF-R-CLW, WEF-R-WMB, and WEF-R-W+L, each supporting different protocol combinations.
  • Whirlpool meters are available in sizes DN 50 to DN 200, with a temperature class of T50 and a measuring range of R80H.
  • Inductive transmission is used between mechanical and electronic parts, and the radio module is replaceable.
  • All models are MID-approved and comply with EN 14154, OIML R49, and ISO 4064 standards.
  • Installation is flexible, allowing for any position, with specific requirements for non-horizontal installations.
  • Data security is ensured through multi-level encryption, and configuration data can be modified remotely.
  • The module is resin-coated for outdoor use and is IP68 rated.
Technical Data:
  • Permanent flow rates range from 40 m³/h to 400 m³/h depending on the meter size.
  • Overload flow rates range from 50 m³/h to 500 m³/h.
  • Minimum flow rates and sensitivity vary by size, with detailed specifications provided for each DN size.
  • Maximum permissible operating pressure is 16 bar across all sizes.
  • Dimensions and weights are specified for each meter size.
Radio Module Specifications:
  • Inductive sensor for counter detection with a battery life of 10 years.
  • Operational temperature range is -10 °C to +55 °C, with storage temperatures from -20 °C to +60 °C.
  • Radio transmission is activated via an actuator on the instrument body.
  • CE certified with European Electromagnetic Compatibility Directive compliance.
Data Transmission:
  • Data transmitted includes sensor ID, consumption data, hardware status, battery level, and alarms for mechanical fraud, reverse flow, low battery, and leaks.
  • Configuration changes can be made remotely or via radio terminal.
  • Transmission intervals and distances are configurable, with options for daily readings and history transmissions.
Wireless M-Bus Protocol:
  • Operates at 868 MHz and is OMS compliant.
  • Supports Walk-by/Drive-by operations with a transmission distance of up to 500 meters under optimal conditions.
