Ok so I have to say that (a) BillA's CPVC flanges with rubber gaskets work well (b) the Yokogawa flowmeter that Brucoman donated seems to produce reasonable results (c) the LCD on this thing is HORRIBLE. It has like a 5 degree range where I can read it and otherwise no joy. I'll get this thing reporting 4-20 mA ASAP. If all goes according to plan I'll have a new test loop set up tomorrow that logs dP and dT (wb) via Labview and I'll just eyeball the flowrate with the LCD readout on the flowmeter. Before I do that though I'm going to do a full range comparison of the readings of the GPI and the Yokogawa.
