XiLogFlow – Flow Data Logger for Water Utilities XiLogFlow is a compact, industrial-grade data logger designed for long-term flow monitoring in central water distribution networks. It delivers high data accuracy, reliable communication and up to 10 years of battery life, making it an ideal solution for District Metered Areas (DMA), consumption monitoring and early leak detection.
Description

Data Transmission

XiLogFlow uses modern cellular communication to ensure stable performance even in challenging underground environments.

  • Communication technology: LTE CAT-M1 with 2G fallback

  • Antenna: internal antenna optimized for chambers, pits and low-signal areas

  • Transmission frequency: once per day (fully configurable)

  • SIM type: embedded roaming SIM with automatic network selection to the strongest operator

 

Data Logging

Built for reliable and continuous flow measurement across utility networks.

  • Data types: 15-minute flow rate intervals

  • Logging mode: average values

  • Minimum pulse width: 10 ms — ideal for accurate pulse counting

  • Integration: compatible with Ovarro Atrium, LoggerVision and other Ovarro monitoring platforms

 

Battery & Operational Life

XiLogFlow provides one of the longest autonomous operating periods available in the market.

  • Battery: 19 Ah Li-SOCl₂ internal battery

  • Battery life: up to 10 years (based on daily data transmission with adequate signal strength)

  • Maintenance: no routine maintenance required — ideal for remote or difficult-to-access locations

 

Environmental Durability

Designed for harsh field conditions typical in water network infrastructure.

  • Operating temperature: –30°C to +60°C

  • Max relative humidity: 90%

  • Ingress protection: IP68 (tested to 4 m depth for 4 weeks)

  • Construction: fully potted, moisture-sealed electronics for maximum durability

 

Physical Characteristics

  • Dimensions: 120 × 80 × 50 mm

  • Weight: approx. 301 g

  • Housing material: UV-resistant and impact-resistant industrial plastic

  • Mounting options: suitable for underground chambers, surface cabinets, valve boxes and above-ground installations

 

Application Areas

XiLogFlow is designed specifically for water utilities and network operators:

  • Flow monitoring in DMA (District Metered Areas)

  • Consumption monitoring in rural or low-density areas

  • Early leak indication via flow anomalies

  • Network balancing and NRW (Non-Revenue Water) analytics

  • Reservoir and borehole flow monitoring

 

Key Benefits

  • Fast installation – true plug-and-play

  • Ultra-low maintenance costs – up to a decade of autonomous operation

  • Reliable communication even in poor signal environments

  • High-quality flow data for long-term analytics and asset planning

  • Seamless integration with professional water utility software platforms
