Apparatus for supporting a fluid flow cassette having an opening for receiving a sensor, the apparatus including a sensor mounted on a support, means to lock the cassette into an insertion position with its opening aligned with but spaced from the sensor along an insertion axis, means to move the sensor relative to the opening to cause the sensor and opening to be brought together, and means to prevent the sensor and opening from coming close enough for the sensor to sealably engage the opening until after the cassette has been locked into the insertion position.
