Subsea ROV work requires high accuracy, high resolution pressure measurement and time-of-flight sound velocity is normally complemented with conductivity for density measurements. The AML-3 RTS is a compact package that is ideal for this task. Alternatively, users can upgrade the AML-3 XC for both logged data and real-time streaming of data.
Why choose AML for offshore construction applications...
You need your kit to work, and you need it to work well! We understand that the most critical part of your mission is high-accuracy depth measurements. Our laboratory tested high accuracy pressure sensor has an accuracy of 0.01% FS, and is suitable for diverse depth ranges (100m to 6000m). Our reliable, swappable sensors measure CTD and sound speed directly, enabling the retrieval of density profiles in the water column.
Given the remote locations of offshore projects, instrument availability is just as important as output data. Post-purchase, we have a global recalibration network, with calibration labs located in Canada, the United Kingdom, the European Union, the United States, Singapore, and Australia. Reliability of access never needs to be an issue again with our unmatched speed of delivery, service and repair.
Unique features of the AML solution:
- Our modular approach to sensor-heads allows us to deliver what you need, fast!
- Our field swappable sensor heads streamline service, maintenance, and recalibration; only the sensor - not the instrument - needs to travel to a recalibration centre.
- Service and calibration is easier than ever due to instrument modularity and our global service and recalibration network.
- Our field-swappable sensor heads increase instrument flexibility; any sensor head can be installed on any instrument, thus ensuring a ‘fit to purpose’ instrument is always available.
