When a California municipality needed reliable level measurement of their sodium permanganate storage tanks, they turned to Flowline. The purple oxidizer is used by their treatment plant to cleanse the taste and odor of the city drinking water. Highly corrosive, vaporous and sticky, plant operators had experienced problems with pressure level sensors due to corrosion, and ultrasonic level sensors due to vapor and the resulting signal attenuation. For this reason, Flowline suggested the use of our non-contact, corrosion resistant, pulse radar sensors that are unaffected by vapor. The pulse radar sensors provide continuous level data to the SCADA system, which in turn, monitors the tanks, and alarms for replenishment. Flowline is reliable level measurement.
