  • Flowmeter
    Patent number: 4335617
    Abstract: A flow transducer assembly (1) comprises a body (2), through which extends a passage (3) for carrying a fluid whose flow-velocity is to be measured. The body defines an inlet mouth (7) for the passage (3) which is so shaped as to provide, in use, a region in the mouth (7) in which the velocity profile across the width of the mouth (7) is substantially uniform. The transducer assembly (1) also includes transducer means (4, 5, 8, 9, 10, 11) for use in performing a direct measurement of the flow-velocity in the said region.
