I use a variety of mag flow meters, all of which have a 4-20mA output
using that and LabVIEW I intend to have a semi-automated program that steps through the predetermined flow rates and when equilibrium (as I define it) is reached to step to the next flow rate
- I have a solenoid setup now but would prefer self-adjusting valves
I don't think it is a problem of bit resolution, the limiting factor will be the repeatability of the valve setting
