When a Montana cattle ranch needed reliable level measurement of their livestock water supply tanks, they turned to Flowline. Cattle graze the ranch and drink from eight new watering stations throughout the property. Each station has a pump house that filters, stores and dispenses fresh water to the troughs. Powder based nutritional supplements are periodically added to the water tanks and hand blended with paint mixers. But after three months of operation, the ranchers experienced several tank overflows. Upon inspection, their contractor determined that the float level switches were sticking due to material build-up. For this reason, Flowline suggested the use of our non-contact ultrasonic level sensors that are unaffected by sticky or coating type media. The integral relays were easily configured to mimic the previous float level switch points, and thus required no changes in PLC programming. The ultrasonic sensor provides switch inputs to the PLC, which in turn, controls the water tank fill valve. Flowline is reliable level measurement. |
