When the Birdsboro, PA water treatment plant needed reliable level measurement of their effluent discharge basin, they turned to Flowline. Effluent flows continuously from the plant to the basin, where a modulating gate valve controls its further release to the Schuylkill River. In addition, two submersible pumps provide backup during peak flows or gate valve failure, and the entire process is level controlled. Hence the sensor, suspended above the basin, must perform reliably across all environmental conditions including rain, wind, snow and temperature extremes. For this reason, Flowline suggested the use of our pulse radar level sensors that are unaffected by the environment, and packaged robustly. The pulse radar sensor provides continuous level data to the local display and PLC, which in turn, monitors the basin and controls the discharge. Flowline is reliable level measurement.
