In order to automatically control the concentration of coating line for coating paper, eliminate unevenness and stabilize the operation, it is most important to diagnose the state of process and improve the facilities and operation condition to keep them in the best condition.
APPEARANCE MONITOR (in-situ type concentration monitor) is installed in the process as the tool for the diagnosis of concentration measurement and its automatic control.
However APPEARANCE MONITOR sometimes couldn't be used effectively, because proper diagnoses haven't been done.
Some problems exist :
·where in the line the monitor is to be installed
·where the sample for analysis is to be taken
·who takes the sample and analyzes
·how the sample is to be taken the sample
·speed and pressure of running fluid
·bubbles
·etc
This time we will show you how we have solved such problems and what data we've got after solving these problems.
