[Swansea Hackspace] Flow sensor

[Tim Clark]

Excellent, that should be good enough for us to install it. As that is 
the last critical interlock we should be able to run the induction 
workshop and get members using it RealSoonNow™.
The purple-violet issue is most probably a software issue on the chip, 
but none of us who have looked at the code can see what it is.
