Flow measurement of highly compressed ethylene is a demanding measuring task. Exact information concerning the flow in each step of the LDPE is paramount for effective process management. Due to the high-pressure levels involved, which can even peak up to 3.000 bar during the process, conventionally used flow meters show a high failure rate and required frequent maintenance. FLEXIM's non-intrusive clamp-on ultrasonic flow measurement technology provides the ideal solution for this measuring challenge. It can help optimise ethylene gas flows at ultra-high pressure and save costs – all whilst outside of the pipe. No pipework, no process interruption, no pressure loss, accurate and repeatable.
