When a Midwest foundry needed reliable level measurement of their scrubber reservoirs, they turned to Flowline. The firm manufactures metal castings and scrubbers are required to separate hazardous pollutants from their exhaust streams. The resulting highly acidic wastewater collects in sumps, where its measured, and periodically transferred for neutralization. Plant operators had problems with a different brand of ultrasonic level sensors, due to condensation build-up on the transducer, and its attenuating effects on acoustic signal transmission and receipt. For this reason, Flowline suggested the use of our reflective ultrasonic sensors that are unaffected by condensation. See why. The ultrasonic sensors provide continuous level data to the PLC, which in turn, monitors the sumps and controls the wastewater transfer. Flowline is reliable level measurement.
