When a West Coast water treatment plant needed reliable level measurement of their stormwater intake vault, they turned to Flowline. Stormwater first enters the plant in a deep rectangular vault with three pumps that transfer the water into the treatment process. During peak inflow, the vault is agitated and often has surface foam. The plant operator said that the previous ultrasonic level sensor became unstable whenever foam migrated under the sensor, and a stand-pipe installation was not desirable due to turbulence. For this reason, Flowline suggested our radar sensors that are unaffected by media characteristics such as agitation, foam and mist. The radar sensor provides reliable level data to the SCADA which monitors the vault and triplex controls the pumps. Flowline is reliable level measurement.
