1、概述在能源计量中波广泛应用的水蒸汽流量及其热能流量的计量,由于它的密度ρ及热焓i的非线性变化,计量有其特殊的困难。但由于蒸汽的广泛应用及能源紧张的现状,参数波动较大,能源计量的准确性又具有特殊的经济意义,因而研制一种既能准确计量它的质量流量,又能准确计量其热能流量的仪器,就具有很高的实用意义和经济价值。过去,一般单位采用定温、定压设计的仪器计量蒸汽的质量流量,再用查表法换算
1. Overview The measurement of water vapor flux and its thermal energy flux, which is widely used in energy metering wave, has its own special difficulty due to the nonlinear change of its density ρ and enthalpy i. However, due to the wide application of steam and the current situation of energy shortage, the parameters fluctuate greatly, and the accuracy of energy measurement has special economic significance. Therefore, a method is developed to accurately measure both its mass flow rate and its thermal energy flow rate Instrument, it has a high practical significance and economic value. In the past, the average unit uses constant temperature, constant pressure design of the instrument to measure the mass flow of steam, then look-up table conversion
