摘要： A flow measurement apparatus is disclosed, and method of measuring flow. The apparatus comprises a flow measurement apparatus comprising: a channel (1) along which the overall rate of flow of fluid is to be measured, a bluff element (7) positioned in the channel (1) which presents an obstruction to the flow of fluid in the channel (1), the bluff element (7) generating vortices in the fluid downstream of the bluff element (7), a transmitter (9) which transmits radiation onto a portion of the surface (8) of the fluid downstream of the bluff element (7), a receiver (9) which is adapted to produce an output signal dependent upon a portion of the transmitted radiation which is reflected from the surface (8) of the fluid downstream of the bluff element (7) onto the receiver (9), and processing means (23) adapted to process the output signal to produce a flow rate signal indicative of the overall rate of flow of fluid along the channel (1).
