To detect the difference between water and coal (solids), we used a very low frequency 10kHz acoustic transducer, mounted on a 60 degree angle aimed at the trough (bottom) of the conveyor belt. The 10kHz transducer is so powerful that the signal bounces and reflects off the top of the water showing a “longer distance”, but will detect coal, iron ore, even fines, or other solids,that can be transported by conveyor
