ABSTRACT:
A transit time ultrasound sensor is employed for the measurement of liquid flow in a conduit, the sensor having an acoustic path formed of materials matched in ultrasound properties to the flow under test, and designed to conform to the shape of the conduit. The sensor can be configured as a clamp on device, wherein the conduit walls are constructed from such an ultrasonically-matched material. Alternately, in a perivascular configuration, the ultrasonically-matched material is operably intermediate the blood vessel and the sensor.
