Neutralization Tank Back-flow Ultrasonic Level Detection

When MIT needed reliable back-flow detection of their acid wastewater neutralization tank, they turned to Flowline. The chemical engineering lab waste drains into under sink lift stations that sequentially pump 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 neutralized batch to the sewer. Regulations require a method for detecting back-flow in the P-Trap, and I&C lead required strong corrosion resistance. For these reasons, Flowline suggested our PP AU18 ultrasonic switch inserted to the base of the outlet pipe. That was nine years ago and its still working today. The level switch provides reliable level detection to the DCS, which monitors the P-Trap and alarms during back-flow. Flowline is reliable level switching.
