... were processed by Labview Programming (National Instruments, USA), and ON/OFF of solenoid valve that was used for controlling water supplying to water tank, was controlled by SSR. The operating time of pumps for disinfectant was controlled quantitatively and Figure 10 showed the flow chart of this control. The controlling programs used in the experiment were programmed by Labview Programming using while-loop, case structure function, array function, and DAQ function and shown in Figure 11, 12, and 13. Figure 11 shows programming for controlling amount of disinfection solution, and Figure 12 for solenoid valve control, and Figure 13 for reading water level sensor. ...
