Underwater ultrasonic thickness gauges are innovations for underwater and industrial inspection

In today's industrial world, especially in harsh marine and underwater environments, material condition monitoring and corrosion control are critical to safety and efficiency. Whether inspecting ship hulls, ensuring pipeline integrity, or assessing the condition of various metal structures, accurate and reliable measurements are required. However, these measurements are often hampered by protective coatings – paint, epoxy or other materials – that are time-consuming, expensive and sometimes even damaging to the structure itself.

This is where the company comes in. Tritex NDT with its revolutionary Multiple echo (Multiple Echo) ultrasound technology.

DRONELAB SIA (Daivings.lv) is proud to announce that we have become official Tritex NDT representative in the Baltic States (Latvia, Lithuania, Estonia). Our goal is to provide professionals in the region with access to world-class measuring instruments that not only make their work easier, but also increase its quality and safety. In this article, we will take a detailed look at the advantages of the technology offered by Tritex NDT and introduce the most popular models – the Multigauge 3000 for divers and the Multigauge 4100/4400 for ROV operations – which are now available in our warehouse in Riga!

Tritex NDT Multi-Echo Technology – A Revolution in Thickness Measurement

Tritex NDT's specialization is unique – the company focuses exclusively on the production of Multiple Echo ultrasonic thickness gauges. What makes this technology so special? Its main advantage is the ability to accurately measure metal thickness, completely ignoring protective coatings up to 20 mm thick.

How does it work? Standard ultrasonic gauges often measure the total thickness of both the metal and the coating, or require the coating to be removed. Tritex Multi-Echo technology sends an ultrasonic pulse through the coating and the metal. The signal reflects off the back wall of the metal and then echoes back into the metal several times. The gauge analyzes the time between these multiple echoes (not the first return signal) to accurately determine only metal thickness.

This approach offers huge advantages:

Time and cost savings: There is no need to waste time and resources removing and then restoring coatings.
Coating protection: The integrity of the expensive and important protective coating is maintained.
Increased security: The need for working with potentially hazardous coating removal processes is reduced.
Accuracy: Provides reliable results even on uneven or corroded surfaces.

All Tritex measuring instruments are also equipped with Automatic Measurement Verification System (AMVS) which checks at least three echoes to ensure that the displayed measurement is true and stable. Intelligent Probe Recognition (IPR) automatically adapts the device settings to the specific probe, improving performance. Tritex devices are known for their robustness, simplicity and reliability in the most difficult operating conditions.

Multigauge 3000 – A diver's best friend underwater

Professional divers performing underwater inspections, maintenance or repairs need equipment that is not only accurate, but also robust, easy to use and reliable in harsh conditions. These are the requirements that the Tritex Multigauge 3000.

This underwater ultrasonic thickness gauge is designed with the diver in mind:

Robust and Durable: Designed to withstand shock and harsh underwater conditions. Tested to work up to For a depth of 500 meters.
Excellent Visibility: Large (10 mm), bright red LED display provides easy reading even in murky water or poor visibility conditions.
Multi-Echo Technology: Allows measurements to be taken through paint, epoxy or other coatings without removing them.
Long Operating Time: The integrated battery provides impressive 55 hours of operation with one quick (2 hour) charge, eliminating the need for spare batteries in the middle of a shift.
Easy to Use: Intuitive control and calibration.
Expansion Options: Easily converted to a system with a surface repeater by replacing the end cap.

The Multigauge 3000 is supplied fully assembled, ready to use straight out of the box in a durable Peli case. The kit includes the device itself, a standard 2.25 MHz probe, spare membranes, oil, test block, tools, charger, instructions and a calibration certificate. In addition, Tritex offers 3 year warranty and a unique bonus – free annual calibration for the entire lifetime of the device!

Section 3: Multigauge 4100 & 4400 – Accuracy for Remotely Operated Underwater Vehicles (ROVs)

As the complexity and depth of underwater work increases, remotely operated vehicles (ROVs) are playing an increasingly important role. To ensure efficient and accurate inspection with ROVs, Tritex has developed Multigauge 4000 series – models 4100 and 4400.

These measuring instruments are designed for installation on various types of ROVs, providing the ability to perform thickness measurements in deep water:

Multigauge 4100: Designed for deep work up to 1000 meters.
Multigauge 4400: More robust, often in a titanium case, designed for work up to 4000 meters.

Both devices retain all the core Tritex values – Multi-Echo technology for measurements through coatings (up to 6mm in standard mode, up to 20mm with Coating Plus+), AMVS and IPR systems, as well as robustness. However, they are supplemented with features that are especially important for ROV operations:

Simple Integration: Light weight, compact dimensions and easy installation on the ROV manipulator or frame.
Data Transmission: User selected RS232 or RS422 The output provides easy connection to ROV data systems for real-time measurement transmission to the surface.
Tritex Communicator Software: The included software allows you to easily display and record measurements on your computer, adding time, date and identification information.
Special Probe Holder: A well-thought-out design ensures proper probe clamping and positioning against various surfaces (flat, curved), which is essential for accurate measurements using the manipulator.

ROV measuring devices are also provided 3 year warranty and free annual calibration throughout the entire operational life, ensuring long-term reliability and investment value.

Application Opportunities in the Baltic States

The advantages of Tritex NDT measuring instruments are particularly relevant in various industries right here in the Baltic States - Latvia, Lithuania and Estonia:

Shipping and Ship Repair: The Baltic Sea is an area of intensive shipping. Tritex gauges allow for thickness checks of ship hulls (steel and sometimes aluminum) within the framework of classification societies' requirements, without removing antifouling or protective paints, both in ports (Riga, Ventspils, Liepaja, Klaipėda, Tallinn), in repair docks, and even underwater by divers or ROV. This significantly reduces downtime and repair costs.
Port Infrastructure: Assessing the condition of piers, piles, breakwaters and other metal hydraulic structures is essential for the safe operation of ports. Tritex allows you to quickly and efficiently check for material loss caused by corrosion, even underwater or in hard-to-reach places.
Oil and Gas Terminals: Regular thickness monitoring of tanks, pipelines and other equipment at terminals in Būtiņķe, Ventspils, Mažeikiai or elsewhere is a critical safety requirement. Measurements through coatings are particularly valuable here.
Renewable Energy: As offshore wind farm development increases (especially plans in Estonia and Latvia), it will be necessary to regularly inspect the condition of underwater foundations and tower structures. Tritex ROV gauges will be an indispensable tool in such projects.
Bridges and Other Civil Engineering Structures: Assessment of the condition of supports, spans and other elements of steel bridge structures (e.g. over the Daugava, Nemunas) that are also underwater or covered with protective paints.
Industrial Equipment: Thickness control of various reservoirs, pipelines, and pressure vessels at production facilities in all three Baltic countries to prevent accidents and ensure process safety.

Tritex NDT instruments offer an effective solution in all these cases, helping to keep infrastructure safe and operational.
