Mobile CRNS: Dynamic soil moisture mapping technology

Finapp also measures soil moisture in motion supplying maps for agriculture and water leaks pre-location.

The Finapp Rover takes our patented technology out of the stationary box and puts it in motion. As a cutting-edge mobile CRNS (Cosmic Ray Neutron Sensing) solution, it creates dynamic maps for agriculture and urban utilities. By measuring neutrons while moving, we supply precise spatial variability maps for precision farming and water leaks pre-location, fully integrated into our Products & Services ecosystem.

Mobile CRNS Technology: High-Resolution Mapping in Motion

Why choose mobile CRNS for mapping & detection?

Our mobile solution adapts to the vehicle and the goal, offering a versatility that point sensors cannot match.

  • Patented Technology: mobile CRNS ensures precise, large-scale, and non-invasive detection of water content, whether in open fields or under city asphalt.
  • Comprehensive Insights: generates high-resolution maps with a footprint radius of up to 10 meters (urban) or larger (rural), measuring water content up to 50 cm deep.
  • Real-Time Monitoring: delivers continuous updates during the survey for proactive management and immediate decision-making.
  • Adaptable to Speed: the system scales with your needs. It can be mounted on slow-moving agricultural tractors for detailed soil moisture mapping or on fast-moving urban vans (requiring multiple probes) to scan city districts quickly.
  • Cost-Effective & Sustainable: reduces water waste, optimizes irrigation, and supports sustainable practices by identifying hidden inefficiencies.

The value of dynamic mapping: efficiency & sustainability

Soil moisture mapping and leak pre-location are critical for modern resource management.

  • Efficient Water Management: ensures optimal irrigation in agriculture, reducing water waste and improving crop yields through data-driven maps.
  • Cost Savings: detects hidden leaks early to prevent water loss (Non-Revenue Water) and avoid costly infrastructure damage.
  • Infrastructure Longevity:  prevents long-term damage to roads and pipes by addressing soil saturation issues proactively.
  • Improved Decision-Making: provides accurate, geolocated data for better planning in both precision agriculture and water network maintenance.

Finapp in Action: 25,000 km of network monitored

Trusted in over 20 countries, Finapp’s mobile CRNS systems have been successfully deployed to monitor over 25,000 km of water networks. This extensive experience guarantees dependable solutions tailored to diverse environments, from rural farmlands to complex urban grids.

While the Rover excels at dynamic mapping, Finapp also offers stationary solutions for continuous monitoring. The same CRNS precision is available for year-round Soil Moisture analysis in fixed locations or for measuring Snow Water Equivalent (SWE) in high-altitude environments.

Soil water content (VWC) is fundamental for assessing environmental risks (landslides, wildfires, floods), but its spatial variability makes estimation difficult. Point sensors are local and difficult to install, satellites have limited resolution, and hydrological models require continuous validation. The CRNS…
