The neutron sensor for field water measurement<\/h1>\n\n\n\n

Thanks to Cosmic Ray Neutron Sensing (CRNS) technology, our patented probe translates neutron interactions into reliable environmental data.<\/p>\n\n\n\n

\n <\/div>\n \n \n The Physical Principle\n <\/span>\n<\/div>\n
\n \n

From cosmic rays to water measurement<\/h2>\n\n <\/div>\n \n Cosmic Ray Neutron Sensing is based on a well-established physical interaction between neutrons and hydrogen atoms in water.\n <\/div>\n <\/div>\n <\/div>\n

Cosmic rays<\/h2>\n <\/div>\n

Cosmic rays interact with the atmosphere, generating fast neutrons that reach the Earth’s surface continuously.<\/p>\n <\/div>\n\n <\/div>\n <\/div>\n

\n
\n\n
\n <\/div>\n <\/div>\n \n\n
\n\n
\n

Hydrogen Interaction<\/h2>\n <\/div>\n

As fast neutrons interact with hydrogen atoms in water, they lose energy and become slow neutrons. The greater the moderation, the higher the water content in the surrounding soil or snow.<\/p>\n <\/div>\n\n <\/div>\n <\/div>\n

\n
\n\n
\n <\/div>\n <\/div>\n \n\n
\n\n
\n

Neutron Detection<\/h2>\n <\/div>\n

The probe measures neutron count variation and translates them into calibrated water content values in real time.<\/p>\n <\/div>\n\n <\/div>\n <\/div>\n \n <\/div>\n <\/div>\n\n \n \n\n<\/svg>\n\n<\/button>\n\n \n\n<\/svg>\n\n<\/button>\n <\/div>\n\n<\/div>\n <\/div>\n<\/div>\n\n\n

\n <\/div>\n \n \n What Finapp did?\n <\/span>\n<\/div>\n
\n \n

From research lab to the field: CRNS made operational<\/b><\/h2>\n\n <\/div>\n \n Cosmic Ray Neutron Sensing has measured water in soil and snow for years, locked inside research projects, custom builds and specialist know-how. Finapp patented a new generation of cosmic ray neutron sensors (CRNS) taking the technology out of the lab and into the field, where water decisions are actually made.\n <\/div>\n <\/div>\n <\/div>\n
\n\n \n
\n\n
\n
\n\n
\n <\/i>\n \n \n <\/div>\n \n\n
\n\n
\n

Built light. Built simple.<\/h2>\n <\/div>\n

Compact, lightweight, datalogger on board. No trenching, no calibration rigs, no dedicated technician: install it on a pole and it starts measuring.<\/p>\n <\/div>\n\n <\/div>\n <\/div>\n

\n\n
\n

Muons: the built-in fact-checker.<\/h2>\n <\/div>\n

Our probes count muons alongside neutrons, validating every reading in real time. Data you can act on the moment it arrives, not after days.<\/p>\n <\/div>\n\n <\/div>\n <\/div>\n

\n
\n\n
\n <\/i>\n \n \n <\/div>\n \n\n
\n\n
\n

From particle counts to decisions.<\/h2>\n <\/div>\n

Raw neutron counts help no one. Our interfaces turn them into answers: when and how much to irrigate, when a basin is approaching a risk threshold, how much water is stored in the snowpack.<\/p>\n <\/div>\n\n <\/div>\n <\/div>\n

\n
\n\n
\n <\/i>\n \n \n <\/div>\n \n\n
\n\n
\n

The result: water intelligence, for everyone.<\/h2>\n <\/div>\n

Growers, utilities and water authorities, not just physicists.<\/p>\n <\/div>\n\n <\/div>\n <\/div>\n \n <\/div>\n <\/div>\n\n \n \n\n<\/svg>\n\n<\/button>\n\n \n\n<\/svg>\n\n<\/button>\n <\/div>\n\n<\/div>\n <\/div>\n<\/div>\n\n\n

\n Insight below the surface\n <\/h2>\n

\n Since fast neutrons naturally penetrate approximately 30–50 cm into the soil, cosmic ray neutron sensor (CRNS) captures hydrogen-driven neutron moderation, revealing root-zone dynamics without inserting instruments into the soil.\n <\/p>\n <\/div>\n
