When Imperial Valley, CA needed reliable level measurement of their water treatment plant’s sewer pump lift station, they turned to Flowline. Raw sewage enters the plant through a narrow rectangular vault with two submersible pumps. Level measurement is critical, but when the vault empties, the pumps are exposed, leaving only two square feet of free measurement space. During which, the operators experienced intermittence with a different level sensor brand due to false reflections. For this reason, Flowline suggested the use of our pulse radar sensors that automatically map and disregard false signals, enabling their reliable use in limited measurement space. The radar sensor provides continuous level data to the SCADA system, which in turn, monitors the vault, and controls the pumps. Flowline is reliable level measurement.
