Batching tank for coatings
Level measurement in the coating batching tank
Process data
    Measuring task:
    
    Level measurement
        Measuring point:
    
    Batching tank
        Measuring range up to:
    
    0.5 m
        Medium:
    
    Hot water with coating agent
        Process temperature:
    
    +20 … +50 °C
        Process pressure:
    
    0 … 0 bar
        Special challenges:
    
    Temperature change from cold to hot, low liquid levels, rapid filling
Application
The press rolls are cleaned during product changes or shutdowns of the paper machine and then treated with a special coating agent. This protects them from adhesions and deposits that could cause the paper web to tear or split in the machine. The coating agent is mixed with hot water in a batching tank at a temperature of 50 °C, and pumped to various points in the machine. To maintain automatic operation, the level in the batching tank must be measured and the filter status monitored continuously.
