Prop Readout on Piper Meridian

I'm starting to fly Mike Stone's Meridian. In this turbine-prop, where do you read out prop - rpm. Throttle controls Torque OK, but while moving the prop affects flight characteristics, I do not see a way to read out the prop rpm directly as on his twin jet-prop Beech 1900D which does have prop rpm instruments.The included FS2K2 Pro Caravan 208b does not appear to show prop rpm instruments either.I bought a book "The Turbine Pilot's Flight Manual", 2nd ed., that explains theory and practical operations of turboprop and fanjet flying (highly recommended by me!). The turboprop instrumentation flow chart shows both torque and prop-rpm instruments off the gearbox off the prop shaft. Are these instruments redundant (although I would assume that with a prop governor, governor-escape, etc. all shaft elements are not direct at all times) or is the prop-rpm needed for the prop setting via the throttle quadrant.
