When a New York manufacturer of commercial truck, bus, train, aircraft and equipment washing systems needed reliable level measurement of their chemical feed tanks, they turned to Flowline. While these systems vary from automated tunnels to manual spray basins, cleaning chemicals are batched and dispensed from their standard tank. Level measurement is used to make each batch and determine when a new batch is needed. The cleaning agents are coating, and their float level switches would inevitably stick, causing system failures and requiring customer maintenance. For this reason, Flowline suggested the use of our non-contact ultrasonic level sensors that are unaffected by coating or corrosive media. The ultrasonic sensor provides continuous level data to the PLC, which in turn, monitors the feed tank and controls the batch process. Flowline is reliable level measurement.
