When a Texas chemical distributor needed reliable level measurement of their hydrofluoric acid bulk storage tanks, they turned to Flowline. Extremely corrosive and vaporous, hydrofluoric acid is widely recognized as one of the most challenging liquids to measure reliably over time. Having experienced ongoing level sensor failures, plant operators asked Flowline to recommend a robust level measurement solution for their extended field evaluation. Three non-contact, stainless steel pulse radar level sensors with PTFE antenna shields were installed. After performing flawlessly for a year, the entire plant was retrofitted with reliable Flowline level sensors. The pulse radar sensors provide continuous level data to the wireless telemetry units, which in turn, remotely monitor the tank levels for replenishment. Flowline is reliable level measurement.
