A cardboard box manufacturer based in Wisconsin, USA required a reliable level measurement of their sumps. They opted for a Flowline product using guided wave sensors with a rod antenna.

Back to Case Studies

After the cardboard sheets are formed and cut to size, the residual water and fiber material are pumped from each machine into below grade concrete sumps. The waste sumps are very turbulent and the splashing fibers stick to everything. Plant operators couldn't find a reliable level sensor that didn't require daily maintenance to remove fiber build-up. For this reason, Flowline suggested the use of our guided wave sensors with a rod antenna that are unaffected by coating. As of this writing, the sensors have been installed for one year and required no maintenance.
 

The guided wave sensors provide reliable level data to the PLC, which in turn, monitors the sump levels and actuates the transfer pumps. Flowline is reliable level measurement.
