一、概述对管道蒸汽流量参数的测量是保证企业正常生产、降低能源消耗的必要环节.目前,在工厂企业中广泛采用DDZ型二次仪表检测管道中的蒸汽流量.但由于要考虑到被测点压力、温度对水蒸汽密度的影响,所以一般来说,被指示的流量必需再经被测点的压力、温度参数的补偿校正后才可得到真实的蒸汽流量值,而这种校正过程一般靠人工查表计算完成.如果需进一步得到热量流量值,则还要再查热焓表.这往往给工厂企业的能耗管理带来很大的不便.随着近年来微电脑的广泛应用,对以上各种参数进行及时,方便地测量、运算,同时提供各种准确数据已由可能变为现实.本文所介绍的蒸汽流量仪是继我所去年制
I. Overview The measurement of pipe steam flow parameters is necessary to ensure the normal production and reduce energy consumption of enterprises.Nowadays, DDZ type secondary instrument widely used in factories and enterprises to detect the steam flow in the pipeline.But due to take into account the measured Point pressure, temperature on the impact of water vapor density, so in general, the flow must be measured by the measured point of pressure, temperature compensation compensation can be obtained after the true value of the steam flow, and this correction is generally By manual look-up table is calculated .If you want to get further heat flow value, but also check the enthalpy table.This often brings great inconvenience to the energy consumption management of the factory enterprise.With the widespread use of microcomputer in recent years, The above parameters for timely and easy measurement, calculation, while providing a variety of accurate data has become possible from reality.This article describes the steam flow meter is following my last year
