ABSTRACT:
An apparatus for measuring an amount of ultrafiltrate produced in a hemodialyzer and a concentration of a receiving solvent employed in the hemodialyzer by means of an ultrasonic wave, comprises: an ultrasonic vibrator; each of an inlet and an outlet flow-rate measuring parts provided with an input flow channel and an output flow channel; and a reflector interposed between the inlet and the outlet flow-rate measuring parts to permit only the ultrasonic wave to pass therethrough, the reflector reflecting the ultrasonic wave so that the ultrasonic wave issued from one of the inlet and the outlet flow-rate measuring parts is directed to the other.
