Process data
    Measuring task:
    
    Level measurement
        Measuring point:
    
    Tank
        Measuring range up to:
    
    0 … 5 m
        Medium:
    
    Water-sand mixture
        Process temperature:
    
    0 … +35 °C
        Process pressure:

Application
Before the settled out sand can be used as recycled material, it is cleansed of organic matter in the sand washing plant. The washed sand is then dewatered in a screw press and discharged into a storage vessel. The discharge of the washed sand is controlled by a pressure transmitter.
