A wide choice of technologies is available for performing level measurement in industrial processes, but there are certain challenging applications for which non-contacting radar transmitters are the most suitable option. Non-contacting radar technology provides a top-down, direct measurement of the distance to the surface of liquids, sludges, slurries and some solids, which is very accurate and reliable.

A key advantage of this technology is that it is unaffected by process conditions such as density, viscosity, conductivity, coating and vapours. It is also an ideal choice for tanks with moving objects, corrosive products and wide temperature and pressure requirements, which have no impact on measurement accuracy.
