Support dual sensors for return flow?

Red cube FT-60 draws 14ma at 8-30 volts. Output (white lead) is open collector, suggested pull up is 1mA, but no more than 15mA. Output is already 'clean' due to 'two-stage comparator', so no filtering needed. May want to put a low pass on the board even if the resistor pads have a trace that would have to be cut just in case this is an issue (around 1kHz cutoff).
