When an Arizona copper mine company needed reliable level measurement of their groundwater remediation tanks, they turned to Flowline. The now dormant mine once processed copper oxide ore with sulfuric acid. Today, it’s an environmental clean-up project focused on the past wastewater, leach and evaporation pond sites. Groundwater is pumped into a filter and neutralization system that recirculates between two tanks. The operator said that past pressure level sensors had failed due to corrosion and clogging, and they needed reliable level measurement. For these reasons, Flowline suggested our 316 stainless guided wave sensors that are unaffected by clogging particulates. The guided wave sensors provide reliable level data to the PLC, which monitors the tanks and controls the remediation process. Flowline is reliable level measurement.
