气介式超声波水位计测量误差改正方法的讨论

气介式超声波水位计是一种通过声波在空气中传播的特性,实时计算声波至水面的距离而测量水位的仪器,无论是接触式水位计还是气介式水位计,在测量过程中都存在着测量误差,由于产生误差原因的差异,其水位改正的方法也不同,本文通过实例阐述现行气介式水位计改正方法的误区。

Discussion on Gas Medium ultrasonic water level gauge measurement error correction methods

Gas Medium ultrasonic water level gauge is a characteristic of sound waves propagating through the air,real-time calculation of the distance to the surface acoustic wave level measurement instruments ,either contact level gauge or air-water level in the measurement process caused a measurement error ,which due to a difference reasons,the water level correction methods are different,This paper describes the misunderstanding existing air-water level correction methods through examples.
