Are you trying to get a more accurate instantaneous flow reading (so you can better see the pulsation?) or totalize how much has been transferred over a period of time?
Just a thought, but since I assume you're using a positive displacement type pump, is there any way for you to use the strokes...
Would anyone have, or know where I might find, some standard railroad drawing templates?
Specifically I'm looking for some Visio shapes to help me with some in-plant rail track layouts I'm doing which will require switches, turn-outs, the typical things you'd see in a plant, nothing fancy...
