GPRS Remote Meter-Reading Large Caliber Gas Meter


FUNCTIONS

1. Micropower technology: the power consumption is less than 10μA at ordinary times, adopt timing detect technique to improve the battery life.

2. Electrical valve technique: adopt electrical valve technique, work reliably and lower loss of pressure.

3. Totally sealed design: all the circuits are sealed by high performance casting glue, so there is no exposed electrode, good leak tightness.

4. Anti-attack of strong electricity or magnet: gas meter will close valve automatically and give indication when being attacked by strong electricity or magnet.

5. Wireless transmission technique: no need of communication cable layout, greatly reduce the installation cost.

6. Micro-computer and microstorage technique: high integrated and high reliability.


HOW TO USE

1. Remote meter reading

The smart gas meter transmits meter data by wireless meter reading network, the management staff can inquiry gas consumption, valve status, and battery status etc, they can also read meter remotely by wireless meter reading software or hand held unit.

2. Close valve remotely

The gas meter will close valve and stop gas supply after get the command of close valve from the wireless software or hand held unit.

3. Allow to open valve remotely

Transmit command of open valve to the gas meter by wireless software or hand held unit, the gas meter will enter into allow to open valve status after get the command, while not directly open valve.

4. Open valve

When the gas meter in the status of allowing to open valve, press the button on the meter shell, the gas meter will open valve to supply gas (note: press the button cannot open gas meter valve to supply gas if the meter is in the status of forbidden to open valve)

5. Close valve when attacked

When the gas meter is attacked by strong electricity and magnet, the meter will close valve automatically. Please remove the attack source firstly, and then press the button to open valve and recover gas supply.

6. Replace battery

It needs to replace battery if the gas meter stops gas supply automatically, the batteries are 3 pieces of AAA alkaline dry battery. When replace battery, open the battery cover, replace the old battery with new one, and then press the button on the meter shell to recover gas supply.

MAIN TECHNIQUES

1. Micropower technology: the power consumption is less than 10μA at ordinary times, adopt timing detect technique to improve the battery life.

2. Electrical valve technique: adopt electrical valve technique, work reliably and lower loss of pressure.

3. Totally sealed design: all the circuits are sealed by high performance casting glue, so there is no exposed electrode, good leak tightness.

4. Anti-attack of strong electricity or magnet: gas meter will close valve automatically and give indication when being attacked by strong electricity or magnet.

5. Wireless transmission technique: no need of communication cable layout, greatly reduce the installation cost.

6. Micro-computer and microstorage technique: high integrated and high reliability.


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 less than 300mm

5. Do not install power socket and wire near the gas line, and the distance shall not be less than 300mm. No power wire and electrical equipment 500mm around the gas meter.

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 of the air inside the gas meter and pipeline
