PCB Etch Neutralization Tank Ultrasonic Level Measurement

When a Canadian manufacturer of printed circuit boards needed reliable level measurement of their neutralization tanks, they turned to Flowline. The firm uses etchants like copper chloride to dissolve unwanted trace material from PCB’s. Each process line generates a corrosive waste stream that flows into small neutralization tanks. There the operator said that prior pressure level sensors had failed due to corrosion, and competitive ultrasonic sensors were erratic due to the limited measurement space in the tanks with pipes, sensors and inflow streams. For these reasons, Flowline suggested our UG06 ultrasonic sensor installed in a standpipe to separate the measurement from those obstacles. The ultrasonic sensors provide reliable level data to the PLC which controls the process. Flowline is reliable level measurement.
