AQUAscat serie

The AQUAscat 1000 represents a 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.

These low maintenance instruments allow for non-intrusive, flexible and unattended operations. Choose between 4 technologies for the most suitable solution for your studies or survey.

AQUAscat 1000R

For the most flexible sediment research, the AQUAscat 1000R has 4 cabled transducers, allowing researchers and scientists to choose between 7 frequencies (300 kHz, 500 kHz, 1 MHz, 2 MHz, 2.5 MHz, 4 MHz and 5 MHz). With cabled transducers, the instrument can transmit and receive sound in any direction. The AQUAscat 1000R has an internal battery, and can be connected to an external battery pack for long-term, unattended research. The instrument has integrated temperature and depth sensors. With an optional turbidity sensor, researchers and scientists can obtain both turbidity and suspended sediment concentration.

AQUAscat 1000S

For simple deployment and operation, the AQUAscat 1000S has 4 integrated transducers (frequencies of 500 kHz, 1 MHz, 2 MHz and 4 MHz). The integrated transducers make deployment simple, and allow operators to save time in the field. The AQUAscat 1000S has an internal battery, and can be connected to an external battery pack for long-term, unattended research. The instrument has integrated temperature and depth sensors. With an optional turbidity sensor, researchers and scientists can obtain both turbidity and suspended sediment concentration.

AQUAscat 1000LT

Measuring suspended sediment concentration has never been easier with the AQUAscat 1000LT acoustic profiler. The latest addition to the well-established AQUAscat range combines cutting edge technology with economic design to give the best value solution for scientists and surveyors. The AQUAscat 1000LT has 2 integrated transducers (frequencies of 1 MHz and 4 MHz), and observe profiles of 2.5m. The self-contained design and rechargeable battery make it easy to deploy and maintain. Suitable for use to 200m, the new AQUAscat can be deployed in rivers, lakes, estuaries and coastal regions.

AQUAscat 1000L

For research in the laboratory, the AQUAscat 1000L is the ideal solution. The instrument is supplied with 3 cabled transducers providing flexibility in operation, as it can transmit and receive sound in any direction. Researchers and scientists can choose between 6 frequencies (500 kHz, 1 MHz, 2 MHz, 2.5 MHz, 4 MHz and 5 MHz). With an optional turbidity sensor, researchers and scientists can obtain both turbidity and suspended sediment concentration.
