When an Oklahoma chemical distributor needed reliable level measurement of their hydrochloric acid storage tanks, they turned to Flowline. The company blends and supplies frac chemicals to drilling companies in the region. HCI is highly corrosive, vaporous and notoriously harsh on sensors and fluid handling equipment. Non-contact ultrasonic level sensors were unreliable due to vapor and Teflon coated guided wave sensors failed over months due to corrosion. The facility operator needed reliability and longevity. For these reasons, Flowline suggested our non-contact radar sensors with rugged FEP antenna shields. The radar sensors provide reliable level data to the PLC, which monitors the tanks and controls the process. Flowline is reliable level measurement.
