When the city of Chicago, IL needed reliable level measurement of the Wrigley Field sewer pump lift stations, they turned to Flowline. During a game, hundreds of toilets, sinks and concession drains simultaneously flush into nearby lift stations. The inflow rates are significant, and the pumps work non-stop to transfer the waste forward. During which, the waste is agitated, and depending upon contents, may have significant foaming excrement floating on the surface. When so, the field operator was dissatisfied with past ultrasonic level sensors that became erratic due to the attenuation of their acoustic signals. They also expressed concern over the narrow vault and sensor mount location that affords very little measurement space. For these reasons, Flowline suggested our radar sensors with narrow beam widths that are unaffected by floating waste media. The radar sensors provide reliable level data to the SCADA system, which monitors the vaults and controls the pump transfer process. Flowline is reliable level measurement.
