When a Mississippi chemical distributor needed reliable level measurement of their terminal tanks, they turned to Flowline. Acids are delivered from manufacturers via railcars, and are pumped into storage tanks for customer distribution via tanker trucks. The operators monitor the filling process and level measurement is critical. But they experienced intermittence from ultrasonic sensors in hydrochloric, hydrofluoric and nitric acids due to vapor, and the resulting acoustic signal attenuation. For this reason, Flowline suggested the use of our pulse radar sensors that are unaffected by vapor, and ideal for corrosive media with our PTFE antenna shield. The radar sensor provides continuous level data to the controller, which displays the remaining height available to fill, and shuts down the pump in the event of a high level alarm condition. Flowline is reliable level measurement.
