摘要
温度漂移是影响超声波流量计测量精度的一个重要因素,本文从算法上提出一种不受其影响的数学模型,以使相应的硬件简单化。该方法已应用在超声波流量计中,收到了很好的效果。
The temperature drift is an important factor to effect the measurement precision of the ultrasonic flowmeter. This paper puts forward a model of maths which has not an effect on the temperature drift, and it makes the relative hardware simple. The method in this paper is used by the ultrasonic flowmeter and a very good effect has been obtained.
