When a San Diego municipality needed reliable level measurement of their chemical storage tanks, they turned to Flowline. Hydrochloric acid and sodium hydroxide are metered into aerated vessels where sewage batches are blended and neutralized. The tank fittings were located next to the side wall, and the operators had problems with a different brand of ultrasonic level sensors due to their wide beam and resulting signal interference. For this reason, Flowline suggested our LU83 ultrasonic sensor which has a narrow collimated beam for limited measurement space. The ultrasonic sensors provide reliable level data to the SCADA, which monitors the tanks and alarms for replenishment. Flowline is reliable level measurement. |
