When a Midwest steel products manufacturer needed reliable level measurement of their corrosive waste water storage tanks, they turned to Flowline. The company manufacturers metallic storage systems, racks and shelving for residential and commercial applications. Prior to metal finishing, the parts are dipped in diluted hydrochloric acid baths to remove particulate, oil or grease. To maintain finish quality, the HCI dip and rinse baths are frequently recycled with the corrosive waste sent to treatment. There the operator complained that previous ultrasonic level sensors became intermittent during the twice daily condensation cycles in the tank. For this reason, Flowline suggested our reflective ultrasonic sensors that are unaffected by condensation. The ultrasonic sensors provide reliable level data to the PLC, which monitors the tanks and controls the treatment process. Flowline is reliable level measurement.
