Revisiting this question after an absence I tried redefining
various values from the above list within \setupFLOWcharts. None
worked.  No doubt there is a magic combination I missed. But more
than one user has been perplexed by this. 

You know I never did figure out the answer to this one. And
factors such as \tfd were still too small. So I used the 
TeX primitive: 
\font\cx=bchr8r at 10pt
 external to any other macro
and for each text string in the chart definition
I used the \cx prefix. This was simple,
controllable, and did not interact with anything else. And the
font came out at the expected size. 

A better (more Contextish) solution is still requested.
