Fill Level Measurement
Fill levels or level measurement can be done with displacement sensors. For precise level control measurement, confocal sensors or laser triangulation sensors are typically used. For long ranges, such as silo fill level, laser rangefinders are used to measure material levels at a longer distance.
Laser Molten Metal Level Control
One of our customers is using the AR2000 laser rangefinder to measure and control the level of molten metal in a furnace.
Molten Aluminum Level
During the casting process, the AR700 laser is used to measure the surface location of the molten aluminum mold. In order to obtain a homogeneous oxide-free cast, the height of the mold must be precisely monitored.
Silo Fill Level
Laser rangefinders can be mounted at the top of silos and aimed down at the surface to measure the fill level of the material in the silo. Due to the long operating range of the sensors, Acuity’s laser rangefinders are suitable for nearly any silo size.
Stockpile Height Measurement for Inventory Management and Overfill Prevention
Managers of bulk solids carefully monitor their stockpile height measurements for both overfill prevention and inventory management. These directors of heaped goods — such as grain, gravel, ore — are often looking for stockpile measurement with high-accuracy, non-contact methods.
