When a Midwest chemical distributor needed reliable level measurement of their sulfuric acid storage tanks, they turned to Flowline. In higher concentrations, sulfuric is exceptionally corrosive and vaporous. Plant operators were dissatisfied with previous ultrasonic level sensors, because vapor attenuated their acoustic signals, causing the sensors to function intermittently, especially during the agitated tank filling process. For this reason, Flowline suggested the use of our radar sensors with PTFE antennas that are unaffected by vapor. The radar sensors provide continuous level data to the PLC, which monitors inventories and alarms for replenishment and safety. Flowline is reliable level measurement. |
