    Abstract: An ultrasonic detector, particularly useful in the level detection of blood within an arterial reservoir, is provided. The detector includes a pair of opposed arms for connection to the arterial reservoir. One of the arms carries a transmitting transducer while the other arm carries a receiving transducer facing the transmitting transducer. A clamping ring is slidable on both arms for forcing the arms toward each other when the ring is moved in one direction and for enabling the arms to move apart from each other when the ring is moved in the opposite direction.
