increase. The visible changes in the curve and the temperature depend on viscosity, steam pressure and
temperature, as well as the software version of the transmitter. If the wash is not reaching the prism, whole
wash system should be examined. There might be blockage in the lines, the wash pressure might be too low
or there might be condensate in the lines because lack of insulation.
Figure 9 Example of successful prism wash
Best way to diagnose and verify successful washing is to log data from the instrument with FC-11. The FC-
11 logs all the diagnostic values, as well as, all the measurement values. As it can be seen from the picture,
the temperature (red) increases and the CALC (blue) decreases with every wash, whereas the CONC
(green) stays stable all the time. This also reveals intermittent problems in the washing systems.
Figure 10 Data shows clearly if the wash is successful or not.
