- I see that the SFI-300 MIDWEST Sight Flow Indicator has a flow direction shown as an arrow. What will happen if water flows in the opposite direction? Will the rotating impeller rotate in both directions? I want to use the indicator on a wakeboard boat to show water being pumped in both directions on a wake ballast system.
- The inlets and outlets for SFI-300 are designed for flow to only be in one direction. You could physically push flow in the opposite direction, but you would risk damaging the impeller, and you would not get a true indication of flow.
