Both Guided wave radar (GWR) level measurement and non-contact radar level measurement have their own advantages and disadvantages, and the best method for a particular application will depend on the specific requirements of the situation.
GWR level measurement is considered to be more accurate and reliable than non-contact radar level measurement, as it is less affected by environmental factors such as foam, dust, or steam, and can measure level over long distances. However, GWR level measurement requires a physical probe to be inserted into the container, which can be a limitation in some applications.
Non-contact radar level measurement, on the other hand, does not require a physical probe to be inserted into the container, making it suitable for use in harsh industrial environments. It is also less expensive than GWR level measurement, but it is not as accurate and reliable, especially when measuring level over long distances or in the presence of environmental factors such as foam, dust, or steam.
