When a San Diego county municipality needed reliable level measurement of their neutralization chemical storage tanks, they turned to Flowline. Hydrochloric acid and sodium hydroxide are metered into wastewater mix tanks where the batches are blended and neutralized. The tank fittings are located next to the side wall, and plant operators had ongoing problems with a different brand of ultrasonic level sensors due to their wide beam angle, and the resulting signal interference. For this reason, Flowline suggested the use of our ultrasonic sensors that have narrow, collimated beams that are ideal for applications with limited measurement space. The ultrasonic sensors provide continuous level data to the SCADA system, which in turn, monitors the tanks, and controls the process. Flowline is reliable level measurement.
