Introduction to Radar Level Measurement
The efficient operation of process plants relies on accurate and reliable level measurement instruments . These measurements are important for optimizing process control, inventory management, and custody transfer, all of which can affect profitability. Level measurement also plays a critical role in safety applications such as overfill prevention. Radar level meter systems are available in contacting and non-contacting versions. Contacting: Contacting is generally a good fit for small spaces and is an easy replacement of older technology such as displacers and capacitance probes. Contacting devices, called guided-wave radar (GWR), are slightly more prevalent primarily because they are capable of providing interface level instrument (e.g. oil and water), as well as standard direct level measurements. Guided wave radar measurement is based on the time difference between sending and receiving a microwave pulse sent down a probe and reflected back to the media surface. For level and inter...
