Refinery Caustic Soda Tank Ultrasonic Level Measurement

When a California refinery needed reliable level measurement of their sodium hydroxide mini-bulk tanks, they turned to Flowline. Caustic is used to remove sulfur impurities from oil and mitigate the corrosive effects of hydrochloric acid, a by-product of the refining process, on plant equipment. To do so, NaOH is injected through metering pumps at eight chemical feed stations. There the operator required reliable non-contact level measurement, NEMA 4X displays and pump control to auto-refill each tank. For these reasons, Flowline suggested our ultrasonic level sensors, coupled with a level controller, mounted in a windowed enclosure. The ultrasonic sensors provide reliable level data to the controllers which display the gallonage and control the transfer pumps. Flowline is reliable level measurement.
