Question

If a customer complains the impeller in his sight flow indicator is not turning, what is most likely the problem?

Answer

Usually the impeller is fouled or the indicator is doing its job and actually indicating no flow.

Question

If a customer claims the plastic impeller dissolved in plain water, what probably happened?

Answer

The customer exposed the sight flow indicator to fluid temperatures of 400-500 degrees Fahrenheit, considerably in excess of the published temperature specification.

Question

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.

Answer

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.
