The invention relates to the technical field of liquid state quantity measurement, in particular to a free liquid level fluctuation sensor and a tank truck. The floating plate assembly floats on the measured liquid, and the floating plate assembly is of a multi-section structure, is connected with each other through a floating plate guide rod and can slide along the floating plate guide rod to realize length change; the adjusting assembly is used for adjusting the length of the floating plate assembly according to the height of the liquid level of the measured liquid, so that the floating plate assembly fits the average inclination angle of the liquid level, and when the liquid level of the measured liquid is in a dynamic state, the average inclination angle of the liquid level is measured through the magnetostriction position sensor. Therefore, the problems that in the prior art, an ultrasonic measurement method for the liquid state quantity cannot effectively receive echoes, processing is complex, the data updating efficiency is low, the overall shaking trend of the liquid level cannot be reflected, and multiple sensors interfere with one another are solved.
本申请涉及液体状态量测量技术领域,特别涉及一种自由液面波动传感器及液罐车,其中,包括:磁致伸缩位置传感器;浮板总成,浮板总成浮于被测量液体上,浮板总成为多段式结构,通过浮板导杆相互连接,可沿浮板导杆进行滑动实现长度变化;调节总成,用于根据被测量液体液面高度调节浮板总成的长度,使得浮板总成拟合液面平均倾角,并在被测量液体液面处于动态时,通过磁致伸缩位置传感器测量液面平均倾角。由此,解决了相关技术中液体状态量的超声波测量法,存在无法有效接收回波、处理复杂、数据更新效率低、无法反应液面整体晃动趋势,多传感器相互干扰等问题。
