If your head spins after reading how amazing one level measurement technology is in comparison to another, understanding the key attributes of these technologies and their applicability to specific processes may help to clear the waters.
When it comes to devices that monitor the level of clean or not-so-clean water – be it in filter beds, wet wells, lift stations, water towers, chemical tanks or open channels – ultrasonic technology emerges on top, followed by radar. It’s true that some level application challenges can be solved by more than one level technology. Yet, no single technology can handle every process, regardless of cost, how powerful the instrument is or how new the technology is.
