Answer

The IC card gas meter is currently the most popular smart gas meter. Many users also have some questions for the use of IC card gas meter.

Here are some kinds of situations that IC card gas meter can not be recharged when the card is inserted it:

1. Card inverted or take the wrong card.

2. Insert and remove the card too fast.

3. The card chip has oil stains.

4. There is moisture or foreign matter in the card holder, etc.

5. The card holder is bad.

6. IC card is damaged.

Answer

First, the smart gas meter with batteries can not continue to use without electricity. You must replace new batteries with generally four 5 dry batteries. It is recommended to use high quality batteries.

Answer

According to the national standard JJG577-2012 "Diaphragm Gas Meter Verification Regulations", the gas meters with a maximum flow rate of not more than 10m³/h are only subject to the first mandatory calibration with a replacement after expiration. The life cycle of gas meters with natural gas as the medium is not more than 10 years, and the service life of gas meters with artificial gas and liquefied petroleum gas as the medium is not more than 6 years.

Answer

(1) The battery is low. Open the valve to change the battery.

If the voltage of the gas meter is too low, the valve will automatically shut off. This is the gas meter under-voltage protection function.

(2) There is no gas volume in the gas meter. The user takes the card to the outlets to recharge and then insert it into the gas meter to open the valve.

Smart gas meters are generally in prepaid mode. When the gas volume is used up, the valve will be automatically closed. When the gas volume is insufficient, the gas meter will have a sound prompt. The LCD will display the gas shortage to remind the user to recharge.

(3) There are strong magnetic objects around.

The smart gas meter will automatically shut off the valve when it is attacked by strong magnetism, indicating the corresponding fault code. First remove the strong magnetic objects around the gas meter such as microwave ovens, induction cookers, rice cookers, etc., and then contact the gas company.

(4) The gas meter has an action with alarm. When the gas alarm found gas leak, it not only can issue an alarm prompt, but also link the gas meter to close the valve. Do not turn on the gas, open the window for ventilation, and go outdoors to contact the gas company.

Answer

1. Interference problems

The IC card gas meter is weak in anti-interference ability, especially in the harsh environment, such as humidity, high temperature, oil smoke, steam and other corrosive places, resulting in IC card read failure when inserted.

2. Battery problems

If the battery power supply is unstable, the battery power is low, or the battery contact is poor. It is easy to cause the valve to shut off for no reason, resulting in the user not being able to use gas normally even after purchasing gas.

3. Valve problems

A valve is a key component that controls the meter, however, the valve's internal leakage, failure, and high power consumption can easily cause the meter  malfunction and make it unable to work properly.

4. Card slot problems

The card slot is the interface part between IC card and gas meter, which is responsible for transferring the information in IC card (user information and gas quantity, etc.) to the gas meter. Some card slots have poor contact with IC card, which leads to failure or error in information transfer and prevents normal gas consumption. On the other hand, the card slot of IC card meter is completely open. If the card slot is damaged by external force, it is very easy to cause the control system to fail and prevent gas consumption.

5. Multi-application card problems

One IC card corresponds to one gas meter and cannot be used interchangeably with other meters and cards. Cards and meters damaged due to man-made reasons cannot be used.

Answer

The diaphragm gas meter is a volumetric meter with optimized flow and low pressure absorption. it is called a diaphragm gas meter because the internal metering chamber adopts a rubber membrane mechanism for gas metering. Due to its features such as accurate measurement and good stability, this type of meter is currently widely used in domestic natural gas metering. At the same time, due to the volumetric metering principle and the structure of the internal membrane module, there are certain requirements for installation and use conditions. The specific requirements are as follows:

Installation Requirements

1) Number of installation

A. Each residents using pipeline gas should set up a separate gas metering device, only one gas meter, and a centralized display metering device should be used for civil buildings;

B. The users living in public housing should install at least one gas meter in each billing unit. If the billing unit is different, a separate meter can be installed separately.

2) Environmental requirements

A. The gas meter should be installed in a dry, well-ventilated place where the air temperature is not less than 0℃, and is easy to check and repair the meter (diaphragm gas meter);

B. It is strictly forbidden to install gas meters in bedrooms, bathrooms, steam boiler rooms, storage places for dangerous and flammable products, and places similar to the above;

C. Gas meters for the users living in public housing and industrial users should be installed in separate rooms;

D. The IC card gas meter is equipped with an electronic control module, so it cannot be installed in damp, rainy and sun-dried places.

3) Gas meter requirements

A. Factory certificate;

B. No obvious damage to the appearance;

C. No more than half a year from the factory calibration date.

Basic requirements for the use of diaphragm gas meters

1. The content of impurities in clean gas and fuel gas should not be too high and should meet the requirements of the "City Gas Design Code". If the content of impurities is too high, it will affect the service life and measurement accuracy of the gas meter;

2. It is suitable for low-pressure gas pipeline network, and the applicable pressure is generally not more than 5kpa;

3. The ambient temperature of the gas meter should be higher than 0°C when artificial gas and natural gas are used; when liquefied petroleum gas is used, it should be higher than its dew point by 5°C.

Answer

The gas meter specifications and models generally refer to the nominal flow rate (m³/h) of the gas meter, such as G1.6, G2.5, G4, etc. When we choose the gas meter with the corresponding flow rate, the maximum flow rate of the gas meter is used as a reference index, and the gas load cannot exceed the maximum flow value (instantaneous flow rate) specified by the meter. Those exceeding G4 are industrial and commercial gas meters (G6-G100).

Introduction to the models and specifications of residential gas meters

Gas meter manufacturers produce gas meters with different capacities and specifications according to various requirements of users. Generally speaking, residential gas meters are divided into three specifications, namely G1.6, G2.5, and G4. The maximum and minimum flow rate (accurately measured) corresponding to the model specifications of meters are as follows:

Model

G1.6

G2.5

G4

Qmax

2.5
