摘要： Apparatus for providing a measure of the time taken for sound to travel a predetermined distance. The apparatus comprises a transmitter electroacoustic transducer (2,46,108) for transmitting an acoustic signal, and a receiver electroacoustic transducer (3,48,108), spaced apart from the transmitter electroacoustic transducer (2,46,108), for receiving the acoustic signal transmitted by the transmitter electroacoustic transducer (2,46,108), when the apparatus is in use. The apparatus has a sound reflective surface (1,91,108) spaced apart from the receiver electroacoustic transducer (3,48,108) so that the latter also receives a reflection of the acoustic signal, and timing electrical circuitry (54) connected to the receiver electroacoustic transducer (3,48,108) which circuitry (54) serves to provide a measure of the time delay between the respective receptions by the receiver electroacoustic transducer (3,48,108) of the acoustic signal and its reflection.
The invention extends to a flowmeter (10) which incorporates such apparatus and an anemometer which incorporates such apparatus. The apparatus can be adapted to measure the speed of sound.
The invention extends to the corresponding methods which make use of such apparatus.

摘要： An ultrasonic flowmeter (10) comprising an elongate duct (36) through which fluid flows when the flowmeter (10) is in use. Ultrasonic transducers (46, 48) are arranged respectively to transmit and receive ultrasonic pulses propagated through such fluid when the flowmeter (10) is in use. Electronic circuitry (54) is connected to the transducers (46, 48) to provide a measure of the time delay between emission of an electronic pulse from one of the transducers (46, 48) and reception of the pulse by the other of the transducers (48, 46). The circuitry (54) is constructed to enable an output to be provided which is dependent upon that delay and which is indicative of the rate of flow of fluid through the duct (36). The transducers (46, 48) are located respectively at opposite ends (34, 40) of the duct (36) and are arranged to transmit and receive ultrasonic pulses propagated through the fluid substantially parallel to the duct (36) from one end (34, 40) thereof to the other (40, 34). The transducers (46, 48) are provided with respective vibratory surfaces (50, 52) which transmit and/or receive ultrasound, which vibratory surfaces (50,52) have a diameter which exceeds the cross-sectional diameter of the duct (36).
