HOW TO USE
During the period of gas
supply, the microcomputer inside the gas meter will automatically subtract the gas
flow, when the purchased amount is used up, the gas meter will automatically
close valve and stop gas supply. At this moment, the customer has to purchase
gas again to open the valve of gas meter.
With support of software and IC card
reader-writer, gas administrative office can manage the remaining gas, total used gas, and total purchased gas
etc. By this kind of meter,
it can improve management efficiency, no need of
house call fee-charge and avoid owing.

INSTALATION
1. The installation
shall be done by the professional person of Gas Power Company, and shall be
installed according to the requirement 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 swiping IC
card, observation and overhaul.
4. The gas meter shall
be installed vertically, cannot slant, and the vertical missing should be less
than 1mm, the distance between gas meter and gas stove should be more than
300mm.
5. Open wire, concealed
wire and power socket is strictly prohibited to install near the gas pipe, and
the distance between them should be more than 300mm. Do not install electric
wire or electrical equipment within 500mm of gas meter.
6. Pay attention to the direction
of gas meter inlet and outlet, and choose the right gas meter, it cannot be
installed reversely.
7. Joint is end face
seal, screw thread is forbidden to be filled with any sealing objects.
8. When the installation is
finished, the gas meter shall be tested for air tightness. And if can be used
only after qualified. Before inflaming, all
the air in the gas meter and pipeline
should be discharged.
DIMENSION
MAIN TECHNIQUES
1. Prepaid RF card
technology: using wireless data transmission, waterproof, moisture-proof and
anti-attack.
2. Micropower
consumption technology: adopt timing test technology, the normal power consumption
is less than 20μA, such technique can prolong battery life.
3. Electrical valve:
adopt modern electrical valve, reliable working and low pressure loss .
4. Totally sealed
design: all the circuits are sealed by high performance casting glue, there is
no exposed electrode, good leak tightness.
5. Anti-attack of
external electricity and magnet: If the gas meter is attacked by external
electricity and magnet, the valve will be closed automatically and give
indication.
6. Micro-computer and micro-storage technique:
high integrated and high reliability.
