Features and Benefits
1. Metering function
This ZG-D-W wireless smart gas meter adopts magnetic collector and photoelectricity direct reading technology to measure the gas consumption.
2. Data wireless transmission
Data transmission with collector device via RF channel
3. Data inquiry
Provide real-time consumption data, meter status and historic data
4. Alarm
Raise the alarm automatically when battery is low
5. Anti-magnetic design
Automatically record magnetic disturbance and close valve to cut off gas supply at the same time
6. Valve control
The valve can be opened or closed by system, concentrator or hand hold unit
7. Local prepayment (optional)
Our wireless smart gas meter supports prepayment through wireless network. The accumulated available purchase amount can be limited on system to avoid hoard on purpose
8. Safety
With highly reliable performance to prevent meter from being destroyed, over temperature, gas leaking and non-metering, etc.
