Cooling Tower Water Sump Reliable Ultrasonic Level Measurement

When a Midwest corrugated paper manufacturer needed reliable level measurement of their cooling tower sumps, they turned to Flowline. The firm produces boxes, inserts and point of sale packaging for beverage companies, and their processes generate substantial heat. Machine temperatures are regulated with cooling water supplied by two towers. There the facility operator experienced float level switch failures due to corrosion, scaling or chatter, and their replacement forced costly downtime. For these reasons, Flowline suggested our non-contact DL14 ultrasonic sensor with four relays installed in a standpipe. The relay set points are easily configured to the previous float switch levels, making integration seamless. The ultrasonic sensors provide reliable level switching to the PLC which controls the cooling tower make up process. Flowline is reliable level measurement.
