ccurate and reliable level measurement is fundamental to the safe and efficient operation of process plants. Level data underpins effective process control, optimised inventory management and precise custody transfer — all of
which directly influence productivity and profitability. In addition, level measurement is central to critical safety applications such as overfill prevention. A broad range of level measurement technologies is available to end users, including differential pressure, capacitance and guided wave radar. Each
technology has proven effective in specific conditions, but non-contacting radar transmitters based on frequency modulated continuous wave (FMCW) technology have emerged as a preferred choice for numerous applications. Non-contacting radar level transmitters provide a direct, top-down measurement that is extremely accurate and reliable, and with no moving parts these devices have minimal maintenance requirements. Because the antenna does not come into contact with the process medium, issues such as coating, corrosion and mechanical wear are eliminated or greatly reduced. This makes the technology particularly well-suited to aggressive chemicals, sticky or viscous products, as well as hygienic PROCESSONLINE.COM.AU
