Abstract
A disposable conduitincludes piezo-electric elementsandand a memory chipin which calibration data specific to the relevant conduit is stored. Before measurement, a non-disposable electrical measuring circuit reads the calibration data out of the memory chipto prepare a calibrating equation or a calibration table. A flow speed of a blood passing through the conduit or a flow rate calculated from the flow speed is corrected in accordance with the calibrating equation or calibration table.
