G4 Steel Case Diagram Prepaid Gas Meter for the Domestic Usage with
IC Card
The Commercial IC Card Intelligent Diaphragm Gas Meter serial
products are applicable for many different kinds of flow volume
range from G1.6 to G4. They are mainly designed for the business
users and users in the catering industry (food & drink
business).
The serial products adopt advanced technologic solutions such as
the CPU card, the ESAM safety module and matching intelligent
controller to meet the requirement of industrial grade product
design. The installation & usage cost is lower and since they
are the extremely optimized, therefore, the best selection to
substitute other products with the same flow volume range.

Install and Use:
1.Gas meter should install at drafty place, which is at least 1.5m
from the source of ignition.
2.Install in bedroom,bathroom is forbidden.
3.Testing under seal state, the pressure should not max working
pressure of gas meter.
4.Using open fire to leak hunting on pipeline is forbidden.
5.Before ignition, the air in gas meter and pipeline should be
evacuated completely.Avoid from strenuous vibration, collision,
inversion in transportation, no sundries can be in the meter,
install valve first.
Features and Advantages:
1. Compact structure, big capacity of 1.2dm3 cyclic volume and
beautiful appearance.
2. Apply Hot-printed technology of international leading level on
register, which insures legible reading never fading.
3. Inside and outside of meter case is electro dusted, which
insures good appearance, moisture-proof, gas corrosion-resistant
and high Impact-resistant.
4. The measuring unit is made of Japanese Copolymerization of
formaldehyde M90-44 (POM), injected by Mitsubishi machine; The high
physicochemical properties, strong reliability, good
self-lubricating property and compactness surpass other similar
products remarkably.
5. The rubber diaphragm is made of Polyester fabric coated with
nitride synthetic rubber, passed more than 200 Million times of
Bally Test, oil-resistant change of mass is less than 65%, the
flexibility is less than 0.45g/cm, the low temperature type
diaphragm can work under -35C ambient temperature. All
specifications comply with National standard and International
standard of OIML R311995.
6. The valve and vale seat are made of imported materials Z-41
Plastic pressure powder, which has been tested by foreign authority
that the vale never distorts, has perfectly anti-function and high
plainness after grind.
7. The material of register cover is Polycarbonate, which has
strong impact resistance and keep the bolt falls into the track to
withstand disassembly.
8. Special screw head and seal avoid illegal demolition.
9. Anti-reverse device completely prevents tampering.
10. The valve with 360 degree rotation has the ability to resist
impurity conglutinates and freezing, and has strong stability and
agility; And high accuracy of low discharge.
11. The upper case and lower case are pressed by a steel band under
a 40ton atmospheric pressure, which insures stability of sealing.
12. 1: 1 gear on the transmission device insures the stability of
metrology.
Maintain:
1. User cannot destroy the lead seal of gas meter, if any abnormal,
please call gas company for checking.
2. Inspect the gas meter in regular period, the the abnormal
situation can be found and handled on time.
3. When the battery is low, please call gas company for replace.
4. Gas meter belongs to measurement tool, it should follow relative
rules.
5. About the situation for difference between electric part and
machinery part. According to relative rules, for the smart meter
with both electric part and machinery in gas meter, if damages of
electric part which cause difference between electric part and
machinery part, choose the machinery part valve.
6. About negative problem. When the rest amount in gas meter is 0,
and user can still use water because of problems of unclosed valve,
the gas meter will record the consumption, and so “Rest Amount ”
display negative, means for user’s overdraw consumption. When user
purchase at next time, it should be reduced at first, no cost loss
for manage department. If individual user didn’t purchase gas for a
long time or there is abnormal in consumption, the manage
department should go for checking on time. Loss which caused by
neglect of checking and managing, the supplier won’t take
responsibility for that.
