Thanks for the feedback but these are in a different league than the one I was looking for. Some time ago I ran across a paddle wheel type flowmeter. It was mounted in a square metal block with a window on the paddlewheel. The block had 1" npt pipe connections. Intergrally mounted within the block ther was a pressure and temperature sensor. Electrical connection was with a 6 wire cable which I think contained 3 4-20ma signals, 24vdc and ground.
The 1" device was under $1500.
Ring any bells?
thanks
