我厂83年从西安仪表厂订购了一套Ⅰ系列仪表,用作本厂乙炔气体的具有温度、压力补偿的流量测量系统(见图1)。原设计的数据为: h_(20)=250mmH_2O;t_(max)=50℃; t_(min)=0℃;p_(max)=0.36kgf/cm~2; p_(min)=0kgf/cm~2;p_a=1.033kgf/cm~2; t_d=0℃;p_d=0.238kgf/cm~2。
I plant 83 years from the Xi’an Instrument Factory ordered a set of I-series instruments, acetylene gas used for factory temperature and pressure compensation flow measurement system (see Figure 1). The original design data is: h_ (20) = 250mmH_2O; t_ (max) = 50 ℃; t_ (min) = 0 ℃; p_ (max) = 0.36kgf / cm ~ 2; p_a = 1.033kgf / cm ~ 2; t_d = 0 ℃; p_d = 0.238kgf / cm ~ 2.
