水蒸气是工业生产过程的主要能源之一,是企业成本核算的重要指标。为了节约能源和降低成本,必须提高目前对水蒸气流量测量的精度。 当前,测量过热水蒸气流量(简称汽流量)大多采用标准节流装置和与它配套
Water vapor is one of the main energy sources in the industrial process and an important indicator of cost accounting. In order to save energy and reduce costs, the current accuracy of water vapor flow measurement must be increased. At present, the measurement of superheated steam flow (referred to as the steam flow) are mostly used standard throttling device and supporting it
