When a Southern California municipality needed reliable level measurement in their sewer pump lift stations, they turned to Flowline. Over the years, the operators had used float level switches and ultrasonic level sensors in their lift stations with limited success. The float switches required ongoing maintenance due to grease build-up, and the ultrasonic sensors would go lost every time foam entered the sump due to signal absorption. For this reason, Flowline suggested the use of our pulse radar liquid level sensors that are unaffected by wastewater variables such as grease or foam. The pulse radar sensor provides continuous level data to the SCADA, which in turn, monitors the sump level and controls the two submersible pumps. Flowline is reliable level measurement.
