Neutralization Tank Back-flow Ultrasonic Level Detection

When Massachusetts Institute of Technology needed reliable back-flow detection of their acid wastewater neutralization system, they turned to Flowline. The chemical engineering lab waste drains into small under sink lift stations that sequentially pump the waste to the basement. There the waste enters a limestone chip tank, where it dilutes and neutralizes for two hours, before the next transfer pushes the previously neutralized batch into the sewer. Regulations require a method for detecting back-flow in the P-Trap, and the maintenance team wanted strong corrosion resistance. For these reasons, Flowline suggested our PP ultrasonic level switch inserted to the base of the outlet pipe. That was nine years ago and its still working today. The ultrasonic level switch provides reliable level detection to the DCS, which monitors the switch and alarms during back-flow. Flowline is reliable level switching.
