Abstract:
An ultrasonic flow sensor probe comprising:a) a probe body;b) at least first and second transducers mounted on said probe body for alternately transmitting and receiving ultrasonic waves passing through a flow volume being measured, wherein said transducers are positioned such that a full cross-sectional area of said flow volume is evenly illuminated; andc) a reflector element on said probe body, such thati) said reflector element includes at least first and second reflector surfaces;ii) said ultrasonic waves transmitted from said first transducer directly illuminate only said first reflector surface and illuminate said second reflector surface only after being reflected from said first reflector surface; andiii) a plurality of wavefronts from said ultrasonic waves transmitted from said first transducer having a planar orientation retain that same planar orientation when reflected from said first reflector surface to said second reflector surface.
