Data to prioritize infrastructure improvements 

Historical flow data will help to inform and prioritize investment decisions to  improve the distribution infrastructure, especially when having multiple telemetry points to detect losses in specific sectors.

More efficient use of the Staff

Telemetry allows to prioritize operational staff time towards solving problems, since they will have to spend less time making rounds to check water flows and to communicate with water users

Increase trust between water users and organization

Capta Hydro telemetry provides objective and transparent information, strengthening trust levels between water users and water distribution organizations, laying the foundations for their further investments

Safety and durability

Anti-vandalism test with portable power tools

Why is it important?

  • Equipment is generally installed in isolated rural areas, without the possibility of security personnel

  • Equipment is installed outdoors and must last at least 20 years without replacement

  • Vandalism risk is real, particularly in developing countries like Chile 

  • Padlocks, bars or conventional steel can be easily destroyed with portable power tools

Resistent Anti-Vandalism Design​

  • 3mm thick steel protection shell, with anti-corrosive paint

  • 4mm thick anti-abrasive steel for internal reinforcement, resistant to power tools.

  • Zamak and chrome nickel safe locks.

  • 2mm thick anti-impact polycarbonate cover
    for solar panel protection.

  • Stainless steel anchor bolts for secure installation, secure inside the protection shell

  • Shock detection alarm (in development)

precise and reliable data


Water flow graph in 7 days, shows high variation

Reliable and high accuracy sensors 

  • Last generation, high precision RS485 Ultrasonic Sensor. Approximately +-0.5mm accuracy in 2 meter range and 1mm in 4 meter range

  • Each data point is composed of 4 height measurements in 1 minute, which allows to compensate for natural variations

  • Sensors feature temperature compensation and equipment design allows for their operation at room temperature


Why is it important?

  • Obtaining accurate flow values is essential to obtain full value from a telemetry solution investment and to improve the water management.

  • A high level of accuracy in sensor height measurement is key to obtaining reliable flow measurements.*

  • Particularly important in canals with flows that are highly sensitive to water level changes


*The accuracy of the Capta CFT 5.4 equipment flow measurement will depend mainly on the precision of the gauging section and associated discharge curve*

adaptability to multiple conditions


For electrical power network availability

In certain installation spaces, solar energy may not be an option, which is why we have developed a version that can be connected to the power grid, to a system of solar panels or a set of batteries up  to 50 meters away from the system.

The Capta CFT-Micro version has the same characteristics as the standard Capta CFT equipment.



For pre-existing telemetry stations and still wells.

The Capta e-CFT consists of the electronics, energization and sensor components, and is designed to be installed in existing telemetry stations or in still wells.

It is an ideal alternative for clients who want to renew their telemetry solution but also want to take advantage of past investments. 

Measurement of multiple canals with 1 system

The Multi-Sensor Module allows measuring 2 or more water levels from just one base telemetry unit, thus saving the client the investment in a second unit.

It is an ideal option to install above canal walls separating parallel canals.

Capta CFT Radar (1).jpg


The Radar Module allows to obtain real time water flow measurements without the need of a gauging section or discharge curve, by measuring the speed of surface water.

It is an ideal option to install in wide, high flow and low slope canals, where the construction of a gauging section is not feasible. CONTACT US FOR MORE INFORMATION
