Stormwater Pump Lift Station Radar Level Measurement

When the California Department of Transportation needed reliable level measurement of the largest stormwater lift station in Los Angeles, they turned to Flowline. Located below the intersection of two freeways, the station is typically dry. But during El Nino rains, it has the capacity to hold and transfer tens of thousands of gallons per hour. The vault is a maze of trash screens and cat walks, and the only level measurement space is a small 2′ x 3′ area in the corner. Operators said that a prior radar level sensor measured intermittently when the level dropped below the catwalk. For this reason, Flowline suggested our LR31 radar sensor with a narrow beam and algorithms to disregard false reflections. The intrinsically safe radar sensor provides reliable level data to the SCADA which monitors the station and controls the pumps. Flowline is reliable level measurement.
