Storage of raw materials and intermediates

From liquid to solid form

In the production of chemicals it is necessary to store widely different products: raw materials must be stocked in order to ensure continuous production; intermediate products have to be temporarily stored before being further processed; and finally, finished products have to wait somewhere until they are shipped. All this makes accurate measurement of vessel contents an absolute necessity.

VEGAFLEX 61 for bulk solids containers

Some basic products for the production of chemicals come in powder or granulate form. The VEGAFLEX 61 sensor, which operates according to the guided microwave principle, is particularly suitable for level measurement of these materials in medium-sized silos. The sensor is completely independent of product characteristics, dust generation and air currents from pneumatic filling. The robust sensor version VEGAFLEX 62 is available for applications in which strong extraction forces arise.

Level detection with VEGAWAVE 62

VEGAWAVE 62 is the ideal solution for reliable level detection of all types of powdery substances. The switching point of the sensor can be precisely adapted to individual requirements by using customised cable lengths.

VEGAFLEX 61 in solvent vessels

Modern production facilities in the chemical industry are often geared for the production of a number of different products. Irrespective of product characteristics, the implemented level sensor must deliver accurate, reliable measurement data. VEGAFLEX 61 fulfils this particular requirement perfectly. The guided microwave measuring principle is not affected by the physical properties of the medium, such as density, temperature, gas stratification, foam generation and dielectric constant. Depending on the application and mounting position, rod or cable versions are available. For products with poor reflective properties or for extremely high accuracy requirements, VEGAFLEX 65 with coaxial rod has proven to be an exceptionally good solution.

Level detection with VEGASWING 63

Beside continuous level measurement, level detection constitutes an important security feature on storage tanks. Many new sensors for continuous level measurement are now certified for overfill protection, but a second physical measuring principle ensures optimal safety as well as redundancy.
Because of the many ways it can be applied, the vibrating level switch VEGASWING 63 is ideal for all measurement tasks connected with the storage of liquids. The recurring test acc. to WHG (Water Resources Act) is performed simply by pressing a key on the signal conditioning instrument – the sensor then corresponds to SIL requirements.
