Abstract (en)
[origin: WO2016005343A1] The invention relates to a device for determining a speed of sound in a fluid (1) in a fluid container (3), comprising a sound transducer (5), a first reflector element (7), which is arranged in a fluid space (11), at least one additional reflector element (13, 15), which is arranged in the fluid space (11), wherein the first reflector element (7) and the at least one additional reflector element (13, 15) are integrally formed in a reference element (17), and a control unit (19), which is designed to control the sound transducer (5) in such a way that a specified sound signal (S) is produced, to determine a first signal propagation time period between a transmission time and a reception time of a first reflection of the sound signal (S) on the first reflector element (7), to determine a respective additional signal propagation time period between the transmission time and a reception time of a respective additional reflection of the sound signal (S) on the respective additional reflector element (13, 15), and to determine the speed of sound within the fluid (1) on the basis of the first signal propagation time period and the respective additional signal propagation time period of the sound signal (S).
