— Solid applications A typical LLT100 application is to measure the level of solids in silos and tanks. These vessels can be found in various industries such as mining, aggregates, chemicals, food and beverages, power, pulp and paper, pharmaceuticals, etc. The high sensitivity of the LLT100 allows level measurements in tall vessels. The transmitter's narrow laser beam can be precisely aimed to circumvent obstacles. Its installation is very flexible, as the transmitter can be placed close to the wall or angled inside the vessel. Finally, material build-up on vessel walls has no effect on the...

— Mixer/obstruction Another challenge in the field of level measurement is obtaining reliable measurements in the presence of obstructions or mixing blades. The very narrow beam (<0.3 degrees) of the LLT100 allows installation of the instrument at almost any place on top of the vessel and its positioning between the vessel wall and the edge of the mixer, thus providing reliable measurements. When it is not possible to avoid the mixer blades, the LLT100 has advanced processing functions that can still perform the measurement reliably by efficiently tracking the real level when the mixer...
