Typical water injection systems use a 1/1 mix of water and ethanol. The ethanol provides freeze protection, and also serves as a fuel source. It's the fuel source part that I was concerned with, as it would obviously skew injector pulse width measurements.

Excellent. You have provided a way to accurately measure the amount of water being sprayed into the intake manifold.
