  • Operates in a climatic environment of 5...55 °C with condensing humidity.
  • Available in different meter sizes with nominal flow rates of 1.6, 2.5, and 4.0 m³/h.
  • Battery-powered with up to 16 years of life, depending on usage conditions.
  • Accuracy class 2 according to OIML R49, with specific error margins for different temperature ranges.
Display and Info Codes:
  • Large, clear display showing cubic meters and decimals.
  • Info codes for leak detection, burst pipes, tampering, dry meter, reverse flow, and radio status.
Temperature Measurement:
  • Continuous monitoring of water and ambient temperatures, with data logged daily, monthly, and yearly.
  • Temperature data can be accessed via optical eye or radio signal.
Installation and Configuration:
  • Suitable for horizontal and vertical installations, with various connection options.
  • Configuration options available for display resolution and encryption levels.
Environmental and Hygiene Considerations:
  • Manufactured with hygienic processes and materials approved for drinking water.
  • Disinfection before dispatch and regular audits ensure consumer safety.
Data Logging: The meters have various data registers including yearly (10 years), monthly (36 months), and daily (460 days) logs. Information codes and meter readings are logged and can be accessed for the latest 50 changes.
Communication Options: The meters support Wireless M-Bus, Sigfox, and Wired M-Bus communication. Wireless M-Bus offers different protocols and reading intervals, while Sigfox allows for sequence data transmission. Wired M-Bus supports communication speeds up to 9600 baud and complies with EN 13757:2013 standards.
Ordering Details: Orders are initiated by selecting the type number, which includes meter type, size, and battery supply. Configuration is completed during programming, and accessories are selected separately.

Display and info codes The water meter can be read from the large, easily readable, specially designed display. The five large figures indicate number of cubic meters. The three small figures are decimals. The sign L (to the right of m³) will always be off when the meter is in operation as it is solely used during factory control and verification of the meter. The flow arrows in the left side of the display indicate water flow through the meter. If there is no flow, all arrows will be off. The info codes in the display have the following meaning and function: Info code flashes in the display...
