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. They had used a different brand of ultrasonic sensors with poor performance because the thick vapor was absorbing the acoustic signal, and causing the sensors to periodically loose track of the level. For this reason, Flowline suggested the use of our pulse radar sensors that are unaffected by vapor or corrosion. The pulse radar sensorprovides continuous level data to the PLC, which in turn, provides inventory and safety alarms to the operators. The rugged sensor has a PTFE probe and coated aluminum enclosure for corrosive media. Flowline is reliable level measurement.
