Sludge level monitoring

The 700 IQ IFL sensor is the newest addition to the YSI IQ SensorNet Process Monitoring System. The digital sensor uses an ultrasonic transducer to measure sludge level height or sludge level depth in water and wastewater clarifiers and thickeners by measuring travel time of ultrasonic echoes. It features intelligent signal processing, graphical display of the echo profile, and an optional non-contact wiper. The IFL is factory-calibrated and ready for operation with input of immersion depth and tank depth. Advanced features allow selection of threshold intensity for the desired measured value, residence time to filter out sludge scrapers, echo tracking, minimum intensity to ignore echoes with low intensity, and evaluation range to limit the measuring range between desired depths.
