I have seen many different ways of doing temperature compensation for an air flow signal when a pitot tube (annubar ) is used. Would there be any good documentation on how to do temperature compensation? There are two techniques that I have seen:
temperature compensation using pv = nrt
COMPENSATION = ((( TEMP_REF + TEMP_ABS_CONV ) / ( TEMP_MEAS + TEMP_ABS_CONV))* (( PRESS_MEAS + PRESS_ABS_CONV ) / ( PRESS_REF + PRESS_ABS_CONV )))
temperature compensation using a square root:
root(COMPENSATION)
temperature compensation using pv = nrt
COMPENSATION = ((( TEMP_REF + TEMP_ABS_CONV ) / ( TEMP_MEAS + TEMP_ABS_CONV))* (( PRESS_MEAS + PRESS_ABS_CONV ) / ( PRESS_REF + PRESS_ABS_CONV )))
temperature compensation using a square root:
root(COMPENSATION)
