The Clear Line Fluid Detector from AMETEK Drexelbrook is designed for pipe and tank applications to monitor the presence or absence of fluid in a pipe and provide complete assurance that the tank is empty. The detector mounts directly into existing pipelines between two standard 150-pound, flat-faced flanges. Without interfering with product flow, it uses RF admittance technology to detect when material is present or absent from a pipe. This is especially important for users of expensive pumps who want to prevent damage or burnout from a pump running empty. Each detector is factory-calibrated to provide reliable, repeatable performance regardless of changes in process fluids and coatings or variations in temperature, conductivity and density. Cote-Shield circuitry ensures dependable detection regardless of conductive coatings or product buildup on the sensor. It can be used for interface detection to accurately determine when a material changes from one phase to another. This is especially useful in processes involving material separation. 215/674-1234; www.drexelbrook.com.
