Parts needed to assemble the chemical doser
In addition to the specific parts needed for the lever arm chemical doser, at least one flow controller (FC) is needed with the exact number of FCs depending on plant flowrate. The FC parts list can be found here.
This page is a work in progress and will not be completed until another meeting with Paul and come lab experimenting on the doser design. It will be done in plenty of time to have an order for parts to go to Honduras in January
