Two-pipe, smart diaphragm gas meter, IG1.6S-W | IG2.5S-W|IG4S-W

The Lora/LoraWAN/NB-LoT smart gas meter from Zenner features remote data transmission. It adopts wide-range gas meter to measure the gas consumption accurately with low loss. Credits can be top up via IC card or remotely through prepaid or postpaid method. Data is transmitted from LoRa wireless network to gateway followed by the public network of mobile service provider. Thus, it features safe and reliable network security. The external case is made of galvanized steel sheet. This gas meter can be used for measuring various gas media like natural gas, town gas, liquid gas, biogas, methane gas, etc.

Features

Automatic meter reading: allow meter reading remotely, where it can be conducted actively or regularly. LoRawan allows customization of the upload period of the data.
Failure report: Errors such as magnetic disruption, valve error, abnormally large flow through amount, meter crash, error report after valve closed automatically will be uploaded to the management system to facilitate management.
Remote top up: In prepaid mode, credit can be top up remotely and thus easy for usage.
Remote valve control: valve can be closed remotely during emergency incident or stop the gas usage of user with overdue bill.
