When a Colorado municipality needed reliable level measurement of their polymer feed tanks, they turned to Flowline. Organic flocculants are widely used in water treatment for clarification. Their polymer chains attract suspended solids to form flocs that precipitate during settling, thus leaving clear water behind. Polymer is very sticky and the operators had problems with previous conductance level sensors that required ongoing maintenance due to coating build-up. For this reason, Flowline suggested the use of our non-contact, ultrasonic liquid level sensors that are unaffected by sticky liquids. The ultrasonic sensor provides reliable level data to the SCADA, which in turn, monitors the polymer feed tanks. Flowline is reliable level measurement.
