Introduction

Cygnus Ultrasonic Thickness Gauge is a peripheral that can be used with the Blueye X3 to measure the thickness of different constructions and materials underwater.

Thickness measurements are verified with a multiple echo technique, and the integration gives reliable measurements on corroded and coated surfaces.

The measurements are given with an accuracy of 0.1 mm, even through coatings and soft marine growth.

Live readings are displayed in the Blueye app, and measurements can be overlayed in video recordings and still pictures.

How to install

Communication cable

The communication cable from the Cygnus gauge body to the Blueye X3 comes pre-installed on your X3. The following instructions describe the steps to connect the Cygnus gauge body and probe handler to the X3 vehicle.

The Cygnus Ultrasonic Thickness Gauge must be connected to Guest Port 1 (GP1).

Attach the probe to the Blueye X3

Assemble the Cygnus gauge and probe as described in Chapter 3 of the Cygnus operation manual.

The mechanical parts needed for installation onto the X3.

Insert the two long screws into the black u-shaped mount.

Insert the short screws on the sides with the washer inside the mount.

Tighten the two side screws, make sure the washer is in place, and the plastic parts can move freely.

Insert the connector for the communication cable in GP1. Make sure the drone is powered off before unplugging/plugging any connectors!

Guide the black guest port cable as shown in the picture.

Connect the communication cable to the Cygnus unit.

Place the plastic wedge between the battery tube and the Cygnus unit.

Use the rubber strap to tighten down the Cygnus unit. You can tuck any leftover cable under the strap after completing the assembly.

Insert the U-shaped mount in the two mounting holes at the front of the drone.

Tilt the probe at a max angle upward while attaching the cable to the zip-tie mounts to ensure it can move freely. Attach the second zip-tie mount and tuck any loose cable under the rubber strap.

App usage

Before diving with the thickness gauge, the probe membrane should be inspected. If there are air bubbles or damage to the membrane, it must be replaced as described in the operation manual.

Make sure that the material type to be inspected is chosen in the Cygnus settings menu. The selected material can be changed at any time during a dive.

Select material on the Cygnus setting page

To display thickness measurements in the video recording, you have to turn on video overlay in the setting menu, and press the record button or (X) when in-dive.

Turn on video overlay to display measurements in video recording

Align the probe to the surface you want to measure, and live thickness readings are displayed. A value is only displayed when it is verified with Triple Echo Verification. When a value is not verified, but the probe is measuring echoes, it will be displayed as dashes.

Measurement value displayed in Blueye App

To capture a still picture of the measurement, simply hold (LB) or (RB) while pressing (X). The still pictures will be included in the automatically generated report. The report can be shared immediately after the dive, and you have the option to add comments.
