When a New Jersey municipality needed reliable flow measurement of their open channels, they turned to Flowline. Sewage enters the water treatment plant through open channel transfer stations, where they measure and regulate the inbound flow rate. The operators had problems with their previous ultrasonic level sensors due to the presence of foam, steam and condensation, that attenuated the acoustic signal and caused the sensors to measure intermittently. For this reason, Flowline suggested the use of our guided wave level sensors that are unaffected by foam, steam, condensation or material buildup. The guided wave sensors provide continuous level data to the SCADA, which in turn, monitors and controls the flow rate. Flowline is reliable level measurement.
