通过测量超声波速度可以估算溶液的浓度。在化工生产液中时常会出现大量的气泡,为了避免气泡对测量的影响,借助微机技术同时测量声速及声衰减,以此判断测量是否受到了气泡的影响且只保留正确的数据用于计算溶液浓度。这样,制成的仪器工作性能十分稳定,可以用于在线分析。 The solution concentration can be estimated by measuring the velocity of the ultrasound. In the chemical production fluid often appear a lot of bubbles, in order to avoid the impact of bubbles on the measurement, the simultaneous measurement of sound velocity and sound attenuation by means of computer technology, in order to determine whether the measurement by the bubble and only retain the correct data for the calculation of the solution concentration. In this way, the performance of the resulting instrument is very stable and can be used for online analysis.
