Sodium Hydroxide Day Tank Ultrasonic Level Sensor

Sodium Hydroxide Day Tank Ultrasonic Level Sensor
Sodium Hydroxide Day Tank Ultrasonic Level Transmitter When a Southeast paper manufacturer needed reliable level measurement of their caustic soda mixing tanks, they turned to Flowline. Sodium hydroxide is widely used to extract lignin, an organic polymer found in plant material, that makes the pulp too rigid for paper applications. NaOH is a highly corrosive and crystallizing media that’s difficult to measure. Numerous day tanks receive, periodically mix to maintain consistency, and dispense the chemical throughout the plant. Here the operators had ongoing level problems with float switches that would stick due to coating and chatter due to agitation. For this reason, Flowline suggested the use of our non-contact ultrasonic sensors installed in a stand-pipe. The ultrasonic sensors provide continuous level data to the PLC, which monitors the day tanks and controls the filling and mixing process. Flowline is reliable level measurement.
