The level measuring system at the Cleansing Service Group (CSG) waste oil facility in Middlesbrough, U.K., is vital to its process. Waste oil is constantly being transferred to and from the tanks, so the system must be accurate and reliable, working with high level alarms to avoid over-filling.
Recently, the facility installed a multipoint level-measurement system for waste oil transfer from Hycontrol after its aging pressure sensors had become unstable, delivering unreliable results. Based on new microwave-based Time Domain Reflectometry (TDR) technology, the system monitors seven tanks ranging from 50,000 to 120,000 liters in capacity. The Reflex VF03 TDR sensors deliver individual tank level readings within an accuracy of ±5 millimeters. In addition, a large custom-built display panel of readings is mounted adjacent to the fill points.
Dual sensors are connected to a designated alarm panel, activating visual and audible alarms for “belt and braces” security if anything affects readings from the level-measurement system.
