HOW TO USE
During
the period of gas supply, the microcomputer inside the gas meter will
automatically subtract the gas consumption, 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 and 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. This kind of gas meter can improve the management efficiency, no need of
house call fee-charge and avoid owing.

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 swiping IC card, observe and overhaul.
4.
The gas meter shall be installed vertically, and cannot slant, and the vertical
deviation should be less than 1mm (the maximum flow rate＜25m3/h), or 0.4% of the meter height (the maximum flow
rate≥25m3/h), the horizontal distance between the gas meter and the gas stove
shall not be less than 800mm.
5.
Power socket and wire cannot be installed near the gas line, and the horizontal
distance shall not be less than 300mm. No power wire and electrical equipment
within 500mm around the 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.
Screw thread is forbidden to be filled with any sealing objects.
8. When the
installation is finished, the gas meter shall be test for tightness. And it can
be used only after qualified. Before inflaming, all the air in the gas meter
and pipeline should be discharged.
DIMENSION
MAIN TECHNIQUES
1.
Contactless IC card (RF card) technology, wireless data transmission, waterproof
, moisture-proof and anti-attack.
2.
Micropower consumption technology: adopt timing test technology, the normal power
consumption is less than 25μA, such technique can prolong the battery life.
3.
Electric machine valve: adopt modern electric machine valve, reliable working
and low pressure loss.
4.
Totally sealed design: all the circuits are sealed by high performance casting
glue, so there is no exposed electrode, good leak tightness.
5.
Anti-attack of external electricity and magnetism: If the gas meter is attacked
by external electricity and magnetism, it will automatically close valve and
give indication.
6. Micro-computer and
micro-storage technique: high integrated and high reliability.
