A measuring apparatus for the determination of parameters of medical fluids with a measured region which including a measuring chamber device for receiving a disposable cassette with at least one measuring chamber through which the fluid to be measured is guided, and at least one measuring element for measuring a measured value whose value depends on the extent of the measuring chamber in a measuring direction and allows the determination of the parameter, or of a value being in a fixed relationship thereto, with a known extent of the measuring chamber. A distance sensor unit is provided which is arranged relative to the measuring chamber such that the measured distance changes relative to the extent of the measuring chamber. A method is also provided for the determination of parameters of medical fluids which can be carried out with the measuring apparatus, and for the calibration of the measuring apparatus.
