new generation infinity modularized smart gas meter .
the new generation infinity smart gas meters follow smart meter design specifications from mainstream countries including the european union, the russian federation and china etc.. we adopted modularized design having the communication module completely separated from metrology part, realized the product combinations of "1 n", that is, gprs, rf or nb - iot, lorawan, sigfox communication modules can be changed on site. it will perfectly adapt to the rapid development of communication technologies, and largely reduce cost related to meter replacement, therefore further bring long-term, stable and valuable services to gas companies.
chromatographic analyzer
facing the trend of energy measurement, goldcard is cooperating with international well-known institutions to develop online chromatographic analyzer, which is expected to be released in 2020.
chromatographic analyzer is an instrument that carries quantitative sample gas into the chromatographic column by carrier gas (usually helium or argon as carrier gas), the components of sample gas were separated by the different distribution and adsorption coefficients of gas phase and fixed solid phase in the column, and can be detected through the detector. the retention time and response value of each component were analyzed qualitatively and quantitatively.
