Mounting directly into existing pipelines between 2 standard 150 lb flat-faced flanges, Clear Line™ Fluid Detector uses RF admittance to monitor presence or absence of fluid, providing complete assurance that tank is empty. Proprietary Cote-Shield™ circuitry ensures dependable detection regardless of conductive coatings or product build up on sensor. Featuring sanitary, crevice-free design, Clear Line works without recalibration on processes where fluids can vary from organics to caustics.
