|When Indiana American Water needed reliable level measurement of their chemical tanks, they turned to Flowline. The municipality provides water and wastewater treatment service to 1.3 million Americans, and reliable chemical automation is core to their mission. Aluminum chlorohydrate is an excellent coagulant that they broadly use in wastewater clarification and sludge dewatering applications. The aluminum salt based chemical is sticky, and it coats equipment and instrumentation with reckless abandon. Plant operators grew tired of repeatedly cleaning contact level sensors, and wanted a maintenance free level solution. For this reason, Flowline suggested the use of our non-contact ultrasonic level sensors. The ultrasonic sensors provide continuous level data to the SCADA, which monitors the tanks and alarms for replenishment. Flowline is reliable level measurement.
