Stockpile Level Monitoring


Service Conditions: Ore can vary from large lump to fines. High dust levels, high winds, rain, high Doppler affect with moving ore. Repose angle of Stockpile will vary with Ore size and moisture content. Ore level can change very quickly in some cases.

Level Technology Choice:  For this application we must use a non intrusive technology. Both Radar and Acoustic technology will work within reason. For high speed fill rates, the Acoustic transmitter will be the best option, as they can attain speed of response from 1-00m (3ft) to 50-00m (150ft) in less than 2 seconds. For dry environments, both the radar and acoustic transmitters will work fine to 50m, even in high dusty conditions. For wet rainy, high wind, dusty environments the acoustic transmitter is the best choice, because of the self cleaning action of the pressure wave affect.

For stockpiles up to 100m (>300ft) in height, the 4 kHz Acoustic transmitter is the only choice.
