Apparatus is disclosed for the measurement and replacement of physiological fluids including a meter for measuring the amount of a physiological fluid flowing through the meter, a first conduit for continuously delivering the physiological fluid to the meter, a second conduit for replacing the measured amount of physiological fluid with a corresponding amount of a replacement fluid, and a pressure equalizer associated with the first conduit for equalizing the pressure in the physiological fluid flowing through the first conduit whereby the flow of the physiological fluid through the meter is substantially unaffected by pressure variations in the physiological fluid itself.
