LISST-ABS Acoustic Backscatter Sensor

Submersible Acoustic Backscatter Sediment Sensor

This is a low-cost sensor designed specifically for measuring Suspended Sediment Concentration at a point. It represents an advance over turbidity sensors. See Related Articles in right column. It is suitable for use in environmental applications, as well as in industry, such as hydropower.


The 8MHz acoustic sensor ‘sees’ all size grains, and unlike turbidity, it sees coarse grains very well.


The LISST-ABS calibration is far less sensitive to grain size changes than turbidity sensors, changing only ~ ± 30% over 30-400 microns.


Operates over a >4-decade working range in concentration!


Tolerates fouling.


The LISST-ABS is easy to integrate into existing sensor platforms.
