Have been working on building a quick pump check piece,partial flow bench if you will.
Looking at cpl different flow meters. Low end pieces that say + or - 1%, 31.-- to 30 gpm. even lowend pieces run $200 , at 60 to check a pump it would pay for itself in cpl uses.

Wondering is any here have any experience with any digital flow meters.

I have drive piece about done, just needs cpl small pieces to have it ready to run. Just need fairly accurate way to check pump flow rate.
