I solved the reliability problem by removing the power relay from the board and soldered in a reed relay. Here is a link to the relay I used.
Overall I am satisfied with the hardware setup now. I like that the flow sensor uses a current loop for noise immunity. I also like that this setup isolates the flow sensor from the controller through the reed relay.
