气体流量标准装置分为原级标准装置和传递标准装置。原级标准装置,是依据流量的基本定义予以实施的装置,即以容积V或质量m作为原始的度量依据,结合时间t的测量,可以得到体积流量或质量流量。传递标准装置一般是通过原级标准装置进行量值传递的、具有良好重复性及稳定性的流量计,
Gas flow standard device is divided into the original standard device and pass the standard device. The original standard device is based on the basic definition of flow to implement the device, that is, the volume V or mass m as the original basis of measurement, combined with the measurement of time t, you can get the volume flow or mass flow. Delivery of standard devices are generally through the original standard device for the value of the transmission, with good repeatability and stability of the flow meter,
