flow transmitter releated question?

Gee, I hate to be obvious but you might help yourself by being a little more specific in your question to us. What kind of flow are you measuring? Here's a list of possible flows measured by mankind:

1. Electron flow in a wire
2. Fluid flow in a pipe
3. Water flow in a river
4. Gas flow in a pipe
5. Air flow over a wing
6. Magnetic field flow in free space
7. Cattle through a corral yard
8. Passenger traffic across Manhattan island
9. Impertinent questioners to this forum
10. Solar wind
11. Heat transfer across a solid media
12. Blood through an artery, vein, heart, lung, or cancerous tumor
13. Concepts spreading across civilization
14. Glacial ice migration
15. Lava flow

Now that I've briefly touched on some of the myriad of measured flows known to mankind, you might also ponder how to measure, record and respond. Please know at least these few things before asking anybody for help. And remember to tell them at least what you do know. For the best way to not seem foolish is to not act like a fool.
