利用９０ 年代电子电路高集成化技术，研制了一种有自由电源的超小型流量积算仪。体积仅为国产表的１／７，供电电源为８６～２６４±１０％ Ｖ。可测量各种气体的流量，测量蒸汽可用压力、温度在线补偿。按国际通讯协议编制的通讯程序可在上位机上实现快捷的人机对话。
Using the highly integrated electronic circuit technology in the 90s, a ultra-small flow totalizer with a free power source was developed. Volume is only 1/7 of the domestic table, power supply is 86 ~ 264 ± 10%. Can measure the flow of various gases, measuring steam available pressure, temperature online compensation. According to the international communication protocol prepared by the communication program on the host computer to achieve fast man-machine dialogue.
