[foxboro] flowrate

We haven't got any flow measurements, but we're using ain and ind blocks
to calculate a flowrate. We take value snapshots every x sec's and
calculate average every 5 min's or so. This is not accurately enough. Is
anyone of you using some accurate calculation to accomplish this? I've
been experimenting with accum blocks, but can't get an acceptabel
accurracy
 
Thanks & Rgds,
