When Suez North America needed reliable level measurement of their brine wastewater storage tanks, they turned to Flowline. The environmental company provides industrial and municipal water recycling services to 16k sites, and reliable level measurement is core to their business. At this Northeast location, the operators experienced intermittent performance from ultrasonic level sensors when the temperature dipped below freezing. The tanks are heated, and in extreme cold, the resulting steam, vapor and condensate attenuated their acoustic signal. For this reason, Flowline suggested the use of our pulse radar sensors, that are unaffected by such variables. The pulse radar sensor provides continuous level data to the PLC, which in turn, monitors the tank, and controls the treatment process. Flowline is reliable level measurement.
