When a US steel company needed reliable level measurement of their wastewater process tanks, they turned to Flowline. Water is used throughout manufacturing and their waste streams are filled with residual particulates, oil, chemicals and dirt. To avoid contacting the media, the operators had previously installed ultrasonic level sensors. They worked well with the exception of foaming waste streams where they had intermittent measurement due to acoustic signal absorption. For this reason, Flowline suggested the use of our pulse radar level sensors that are unaffected by foam. The pulse radar sensors provide continuous level data to the PLC, which in turn, monitors the tanks, and controls the treatment process. Flowline is reliable level measurement.
