Record Pressure using voltage as Reference

Hello All, 

 

I am working on a transducer and I am new to labview. I have struggled a lot with figuring out how to properly use labviews tools to create this program but this is what I have so far. The concept of this program is to use voltage a reference and when voltage changes from above 5V, it record one finite number and vice versa when voltage is less than 5V. I am using an optoisolator, so at pressure high, voltage should be 8V and at pressure low, voltage should be at 0V. I need to record 5 separate pressures for 5 different channels. I have created a truth case for each channel and used flags to create a chain of command. I am having issues actually recording the pressure correctly and maybe an issue with my flag set up and shift registers. Please let me know what I can do to correctly record the finite pressure. 

 

Thank you
