Internal CPU provides all functions usually built in electronic flow meters, incl. low flow rate correction, frequency response setting, bandwidth of sensitivity setting at low flow rates, etc.
The traditional neural network correction has a good adaptivity to the noise. But with a stronger lowfrequency space noise, the correction effect is very poor.
传统的神经网络非均匀性校正算法对噪声具有较好的自适应性，但当空间低频噪声较大时，校正效果明显下降。

According to the analysis of the high and lowfrequency parts in the equation of integral specific force, a precise velocity error correction algorithm is presented.
