Aquatec Group Ltd

- Acoustic suspended sediment profiler

The AQUAscat 1000S represents a new generation of high frequency acoustic instrumentation. It has applications in sediment transport studies, including measurement of suspended sediment profiles, precision altimetry, dredge plumes and turbulence.

The AQUAscat transmits pulses of high frequency sound on up to four transducers, each of which may operate at a different frequency. It measures the sound scattered by sediment or other suspended materials at discrete spatial intervals programmable from 2½ millimetres to 4 centimetres. For altimetry, this may span a few tens of centimetres; for monitoring sediment suspension profiles, a total range of around 1- 2 metres is typical; while dredge plume estimation may extend to 10 metres. The instrument is supplied in a subsea housing suitable for long-term unattended deployments. Batteries for various deployment schedules are available to order.

Key features

  • The AQUAscat 1000S can observe profiles of up to 10 m.
  • Using set frequencies of 500 kHz, 1 MHz, 2 MHz and 4 MHz, the AQUAscat 1000S allows you to determine the mean grain size and concentration of suspended materials.
  • The AQUAscat 1000S is a self-contained instrument with 4 integrated transducers, allowing simple deployment and operation.
  • Once you have setup the burst sampling in AQUAtalk, you can be confident that the AQUAscat 1000S is operating at set intervals chosen by you.
  • For long-term deployments, the AQUAscat 1000S can be connected to an external battery pack.
  • The instrument has integrated temperature and depth sensors to give you a better understanding of the water environment.
  • Aquatec offer an optional turbidity sensor that can be integrated with the AQUAscat 1000S. This provides a separate single point measurement of turbidity, giving optical measurements as well as acoustic. This feature is ideal for water quality monitoring, dredge monitoring and aquaculture projects.
  • The AQUAscat 1000S can be used in water depths of up to 1000 m.
