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