IOT Module Smart Gas Meter

In accordance to the market needs, Zenner developed the IoT module smart gas meter integrated with the Internet of Things technology. It has modular structural design with independent plug in option and IC card gas meter as base (or not IC card). Communication module such as GPRS, NB-IoT is equipped based on your needs and the network coverage at our customers region. Besides, the communication module can be shifted freely and thus features strong adaptability to the network.

Features
  • Allow credit metering and gas metering, can be switched among each other.
  • Allow 24 hours usage sampling for big data analysis.
  • Automatic clock synchronization when connected to the network to ensure clock accuracy.
  • Confirmation on opening the valve upon connected to electricity to ensure safe gas usage. Confirmation is required to open the valve after exception handling completed to ensure normal gas meter operation.
  • Allow tiered pricing in accordance to warm or non-warm season, confirmed according to the gas meter function
  • Self-controlled automatic data upload to the network to identify the usage data of the user.
  • Automatic uploading error report to notify the gas company when exception occurred.
  • Valve can be closed remotely in accordance to emergency incident or payment overdue usage.
  • Allow checking on the user’s history usage remotely
