论文摘要
考虑到可以集成到各种测量系统中的IST系列的声流速度和方向计。根据自由流速度进行测量管中流量曲线的模拟。已经开发了一种测量方法,该方法使用了反射从换能器反映的重复声信号的传输时间,这使您有可能考虑时间硬件延迟和测量基础长度的变化,这会影响声音和流动速度的确定,同时且频率较高的频率频率范围的同时测量声音速度的准确性。
Acoustic flow velocity and direction meters from the IST series, which can be integrated into various measuring systems, are considered. The simulation of the flow profile in the measuring tube was carried out depending on the free flow velocity. A measurement method has been developed that uses the transit time of repeated acoustic signals reflected from the transducers, which makes it possible to take into account time hardware delays and a change in the length of the measuring base, which affect the determination of the speed of sound and flow, while increasing the accuracy of measuring the sound speed parameters with simultaneous measuring the flow velocity and temperatures for liquid media of different densities.
