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.
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.
