Process Controller

• Gemma and Ian set up the process controller over the weekend but empty state was not working correcting and the value shut off after it opened.
• Monroe helped solve the problem by creating a new empty state
• Problem with previous old state unknown

Running Experiment

• Filled the bucket and set up the automated process controller to collect data
• Pressure data is being collected per second

Next Week

• Analyze collected data
• Make necessary changes to set up (position pressure value so it cannot be moved)
• Run a test with a know initial level of water in clay pot

New Setup

• Attached pressure sensor at the bottom of collection bucket
• Will manually empty bucket when it fills
• Determined that the clay pot will not affect the water level in the collection bucket

Process Controller

-Fixed pressure sensor issue (pressure not being recognized by process controller)
-Deleted "Empty" state
-No longer automated, locked in manual "data collection state"

Next Week

-Have several runs of data
-Analyze data
