For hydrographic applications

AML-1 with SV sensor

In addition to accurate sound velocity profiles, multibeam echo sounders require sound velocity measurement at the transducer head to correct for ray bending.

Why choose AML for hydrographic applications...

We’re all about getting you the right kit, at the right time, in the right place. We know you’re under a lot of pressure, and we believe actions speak louder than words. AML offers the fastest delivery time in the market for CTD and SVP instruments. 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.

How it took off...

In 1995, AML invented time-of-flight sound velocity (SV) for oceanography, a solution 10x more accurate than CTD derived sound velocity. We have more experience in these sensors than any other company in the world: over 25 years. To date, AML has manufactured tens of thousands of SV sensors for acoustic systems. Our SV sensors are endorsed by all of the large multibeam manufacturers: Kongsberg Discovery, Norbit, R2Sonic, Ping DSP, Teledyne Reson, and Imagenex. Indeed, our time-of-flight sound velocity is now the market standard for multibeam sonar correction.

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 increase instrument flexibility; any sensor head can be installed on any instrument, thus ensuring a 'fit to purpose' instrument is always available.
  • Our field swappable sensor heads create in-field redundancy; sensor-heads can be moved or re-deployed to the most critical asset.
  • Our field swappable sensor heads streamline service, maintenance, and recalibration; only the sensor - not the instrument - needs to travel to a recalibration centre.
