BURKERT8700型气体流量计在大致可分传播速度差法(包括：直接时差法、时差法、相位差法、频差法)波束偏移法、多普勒法、空间滤波法及噪声法等类型，如图所示。其中以噪声法原理及结构*简单，便于测量和携带，价格便宜但准确度较低，适于在流量测量准确度要求不高的场合使用。由于直接时差法、时差法、频差法和相位差法的基本原理都是通过测量*声波脉冲顺流和逆流传报时速度之差来反映流体的流速的，故又统称为传播速度差法。其中频差法和时差*服了声速随流体温度变化带来的误差，准确度较高，所以被广泛采用。按照换能器的配置方法不同，传播速度差拨又分为：Z法(透过法)、V法(反射法)、X法(交叉法)等。波束偏移法是利用*声波束在流体中的传播方向随流体流速变化而产生偏移来反映流体流速的，低流速时，灵敏度很低适用性不大．
