一、温压补偿问题利用流量积算仪温压补偿会解决温度压力变化造成的误差问题。但是作者也发现有企业进行了温压补偿仍然存在总表与分表之和较大误差的问题,这是由蒸汽类型选择不当造成的。在流量积算仪设定蒸汽类型时选择了饱和蒸汽,而实际使用的是过热蒸汽,密度误差造成了蒸汽质量计量的误差。因此在选择蒸汽类型时应根据实际用汽类型而定。二、流量计引入的误差企业用户在选择孔板流量计作为总表时由于实
First, the temperature and pressure compensation The use of flow totalizer temperature and pressure compensation will solve the error caused by temperature and pressure changes. However, the authors also found that there is still a large error in the sum of the total and subscales due to the temperature and pressure compensation of the enterprises, which is caused by improper steam type selection. Saturated steam is selected when the flow totalizer is set to steam type, whereas overheated steam is actually used, which results in errors in the measurement of steam mass. Therefore, the type of steam should be selected according to the actual type of steam. Second, the error introduced by the flow meter Business users in the selection of orifice flow meter as a total table due to the fact
