Solids Level Measurement in Wet Sand Bunker
Prevent overfills with accurate level measurement solutions designed for low dielectric media and extreme conditions.
Reliable Level Measurement with Active Shield Technology
Wet sand can be a challenging material to handle. Its hydrophilic nature encourages caking and clumping, making level management in wet sand bunkers difficult. Wet sand is also abrasive, which can cause wear and tear on measuring devices. Manufacturers using wet sand bunkers need a level management solution that can withstand heavy loads and caking, and is resistant to abrasion.
