High and dusty
Flour is usually stored in narrow, 30 m (98.4 ft) high concrete silos. For space-saving storage of several types of flour, the individual storage cells are approx. 2 x 2 m (6.5 x 6.5 ft).
For applications in solids, the choice of measuring principle depends not only on the measuring range, the degree of dust generation and dielectric constant of the product. Large extraction forces during the emptying process also play into the equation and may cause mechanical damage to the measuring instruments. In many cases, a weak ceiling construction will not allow measurement with a contacting measuring principle.
Level measurement with VEGAPULS 68
For measurement in the flour silo, radar technology offers the advantages of contactless measurement. Since dust particles have only a minimal damping effect on the microwaves, the VEGAPULS 68 radar sensor works well even with pneumatic filling. The high sensitivity of the sensor also guarantees high performance for varying surface geometry.
The optional swivelling bracket enables optimal alignment to the product surface and reduction of false echoes from
the vessel wall.
