When a Virginia water treatment plant needed reliable level measurement of their chemical feed tanks, they turned to Flowline. The plant injects sodium permanganate and manganese sulfate in their drinking water filtration process for taste and odor control. These purple and red-brown oxidizers have the viscosity of ink and are notoriously harsh on fluid handling equipment and sensors. The operators complained that previous float level switches were unreliable, as they would stick due to coating and eventually fail due to corrosion. For this reason, Flowline suggested our non-contact ultrasonic sensors that are ideal for coating and corrosive chemicals. The ultrasonic sensors provide reliable level data to the SCADA, which monitors the inventories and alarms for replenishment. Flowline is reliable level measurement.
