6 surrogate gages w/acoustics




ResultsMulti-frequency acoustics, laser diffraction, turbidityTesting since 2007

Acoustics – best surrogate technology

1.5 to 3MHz generally work best


2 ranges 0.87 to 0.93 Total, fine, and coarse fractionsLISST: R2 = 0.62 (when working)

Turbidity: R2 = 0.65 – 0.92Improvement over traditional transport curves


Real-Time Estimates on the Web

Automation is key!

Moving forwardNeed for automated processing softwareAbility to market



Agreeing on methodology:

SNR vs Signal Strength# of cells needed (and SDI-12 limitations)Negative attenuation

Voltage regulation
