Barrow G1/4" Flow Meter with 3-Pin Output, Black

I bought two of these for a dual loop system build. Neither worked very well and would not register a RPM signal to the MB. These are just the flow indicators with a circuit to make it a flow meter added on. So it could be used as a flow indicator without the meter function attached. However I had a hard time just keeping the paddle spinning inside this as well, even with a D5 vari running full speed and using the medinum flow reducers to speed up flow through the flow meter. These are just crap and you should look elsewhere. I also tested the bitspower version and had the same issues, so this is a true knockoff I guess.
