Storage towers and chests
For continuous operation, large quantities of the prepared stock are necessary. The material is held in storage towers with capacities up to 2000 m3 volume and up to 30 m (98 ft) height. Also product from the pulper is stored in similar towers and chests. Large throughput and internal stirrers ensure a homogeneous substance.
Level measurement with VEGAPULS 66
The level measurement must deliver reliable information on the contents of the towers. A VEGAPULS 66 radar sensor with a DN 250 flange and large horn antenna is best suited for the measurement in the upper part of the towers. Unaffected by the difficult measuring conditions in the towers, the sensor delivers absolutely reliable measurement data. Compact bridges inside the tower prevent measurement all the way to the bottom of the vessel. For that reason, a separate sensor is implemented for the required level measurement in the lower area of the tower.
Level measurement with VEGABAR 54
The material is made pumpable by mixing in process water with an agitator. The additional level measurement in the lower range detects the substance suspension and prevents the stirrer from running dry. For this application the pressure transmitter VEGABAR 54 with the ceramic CERTEC- measuring cell in combination with a ball valve fitting is used.
