M-Bus Remote Meter-Reading Gas Meter
This series smart gas meter needs to work together with concentrator (collector) and management software to realize remote meter-reading function.
After build up the meter-reading system with smart gas meter, concentrator (collector) and upper computer, the management department can read the gas power consumption at any time.
And before reading the meter, please download meter Add into the collector.
FUNCTIONS
1. Remote meter reading
The management staff can inquiry gas consumption via sending command in the software.
2. Close valve remotely
The gas meter will close valve and stop gas supply after get the command of close valve from the software.
3. Open valve remotely
The gas meter will open valve to supply gas again after it receives the command of open valve from the software.

MAIN TECHNIQUES
1. Automatically memory the wheel code position and no need of initiation, accurate meter reading.
2. Avoid external strong magnetic attack, high performance of anti-interference.
3. Adopt M-BUS, RS-485 communication port, long distance communication.
4. No need of power supply, user can get the used gas volume from the mechanical wheel directly, long service life and low maintenance cost.
INSTALLATION
1. The installation shall be done by the professional person of Gas Power Company, and shall be installed according to the requirement of code for management of city gas engineering
2. The gas meters are forbidden to be installed in the bedroom, bathroom and the place where there are flammable, explosive and dangerous goods.
3. The gas meter shall be installed in the good aeration place, and shall be convenient for reading, observe and overhaul.
4. The gas meter shall be installed vertically, and cannot slant, and the vertical missing should be less than 1mm, the horizontal distance between the gas meter and the gas stove shall not be less than 300mm.
5. Do not install power socket and wire near the gas line, and the horizontal distance shall not be less than 300mm. No power wire and electrical equipment around the gas meter within 500mm.
6. Please pay attention to the direction of inlet and outlet, and choose the right gas meter, because it cannot be installed reversely.
7. Screw thread is forbidden to be filled with any sealing objects.
8. After finish the installation, should test the leak tightness. And if it is qualified, then it can be used. Before inflaming, should discharge all the air in the gas meter and pipeline
