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
