When a California wastewater treatment plant needed reliable level measurement of their wash down sumps, they turned to Flowline. The facility and equipment are pressure washed on a regular basis to remove waste, dirt and chemical residue. These waste streams flow into one of two sumps, that collect and transfer the media into treatment. There the operators had problems with ultrasonic level sensors that performed intermittently when the media foamed, and thus absorbed the acoustic signal. For this reason, Flowline suggested the use of our pulse radar sensors that are unaffected by surface foam, and ideal for waste sumps. The pulse radar sensors provide continuous level data to the SCADA system, which in turn, monitors the sumps, and controls the pumps. Flowline is reliable level measurement.
