Looking at it this way, all our instrument catalogs show paddle wheel type flow meter as least restrictive for this type of flow / pressure rates.
We use a paddle wheel type sensor at AVT and it costs thousands of dollars, for reasons I do not understand.
If you use a large wheel, and jeweled bearings with 1/2" passage, the loss of flow will be near zero.
Price should be cheap, I would say 10-15$ less then a MAG pump.
We would not need an AL case, stator assembly, nor volute chamber cut.
Would not even need a circuit board, our hall sensor can handle direct voltage.
If it becomes popular, will just use full injected plastic case, since it will be a simple 2 part mold.
Great you guys like the idea, because I do not want to go back to pump designer and ask him for more noise!
Will work on it this weekend.
But we still need a programmer, anyone know of someone that can help?
