Pre Paid Meter On LoRa WAN have the features of compact size, beautiful appearance, high sensitivity, accurate measurement, good stability, strong reliability, high-pressure resistance, corrosion resistance, longer service life and easier maintenance. They are suitable for accurate measuring the flow rate mediums of liquefied petroleum gas,natural gas and town gas, etc. from 0.016m3/h to 6m3/h respectively. Among the above gas meters, the intelligent integrative gas meters have really realized the integration of machinery and electron, besides the basic prepaid function and mechanical counters, they also have LCD to inform the consumers the inner information of the intelligent gas meter. Gas Companies can realize and provide the automatic management for their consumers.
