Until they’re delivered, wood pellets are stored in silos of corrugated sheet metal up to 30 m high. The large storage capacity allows the supplier to respond to the increased demand during the heating season and utilize their production equipment continuously throughout the year. Reliable measurement of silo contents is necessary for optimal planning of material logistics. VEGAPULS 69 is perfect for measuring the level in the pellet silo. Unaffected by dust, temperature fluctuations and the corrugated vessel walls, it detects the filling height of the pellets in the storage silos with great reliability.
