Bill I have a question about dP measurement. It seems to me that the easiest way to deal with all the different possibilities of tubing and fittings and such is to:
1) zero the xmitter
2) Run a length of the tubing to be used over the flow range of interest (blank)
3) Cut the tubing in half, mount block/rad, and repeat (sample)
4) sample - blank = dP of only block/rad (this takes care of the dP of crosses and fittings and tubing and all leaving only wb).
Is that unnecessarily complicated? I was concerned that the friction factor of clearflex or silicone would be difft enough from copper pipe to make doing a calibration with just copper pipes of difft ID to be a mistake.
