Remotely capture A-scans at height and in hard-to-reach spaces


Developed in partnership with Cygnus Instruments, the UT Payload turns the Elios 3 into a flying UTM gauge that can take accurate thickness measurements backed up with high-resolution A-scans in the most challenging areas. Equipped with the Elios 3 UT, industry professionals can perform regular integrity inspections in minutes - reducing the probability of unplanned downtimes.

Location-Tagged UT Measurements

Live 3D data localization

The Elios 3 can accommodate the UT Payload in parallel with the LiDAR payload enabling precise localization of the measurements on a digital twin of your asset during data capture.

Combined with the Asset Management software extension and Cockpit’s Live Map widget, the location-tagged UT measurements provide exceptional situational awareness, allowing you to easily track the completeness of your inspection.



Smart Couplant Dispenser

Optimal ultrasound coupling

The Elios 3 UT Payload features a remotely operated couplant dispenser with the probe to ensure just the right amount of couplant is dispensed for perfect ultrasound transmission into the material under test. The operator can monitor the couplant level through Cockpit and return home for a quick refill or rapid swap of the dispenser’s syringe when running out of gel.


Smart Probe Arm

The smartest probe arm ever built on a drone.




Modular Probe Head

A comprehensive selection of probes & hoods

The Elios 3 UT Payload features a set of probe hoods to match the shape of various surfaces as well as interchangeable twin crystal piezo-composite probes with the choice of 2MHz, 5MHz, or 7.5 MHz. The probes are particularly suited to measuring heavily corroded metals and feature an Echo-Echo mode to measure through up to 1 mm (0.040 inch) of surface coating.

Cleaning Module

Never miss a measurement

The probe head can be replaced with a cleaning module to remove deposits and prepare surfaces for measurement. Thanks to location-tagging, the user can easily return to the cleaned location to perform the measurement with the probe head attached.

Live A-Scan

Refine measurements in real-time

Cockpit’s Live A-Scan widget provides operators with advanced measurement controls, enabling either fully automated or manually obtained measurements using adjustable gain and gates. This flexibility allows users to refine measurements on the spot even in less-than-ideal conditions.



Advanced Data Post-Processing

Convert UT data into actionable insights

Review your data points in post-processing using the Elios 3’s companion software, Inspector 5.

Navigate through POIs


Navigate through POIs

All data points from your flights are displayed and located in a digital twin of your asset, easing navigation between points of interest.

Review and refine measurements


Review and refine measurements

During the analysis, the A-Scan is retraced in the software, allowing you to verify the measurement or refine it by re-selecting the most appropriate echo signals.
